Setting Aside Half the Earth for Nature

This article appeared in the July 2018 issue of Planning magazine. Author Timothy Beatley is the a professor of sustainable communities at the University of Virginia, and director of Biophilic Cities.

It is a bold goal: That we might dedicate half of Earth’s surface to nature. Biologist and conservationist E.O. Wilson calls it a conservation “moonshot.” He believes it is the only hope we have to forestall the immense loss of global biodiversity we are facing and protect 85 percent (or more) of the world’s species.

The places we have the opportunity to manage for conservation to protect the most species will likely be scattered, though hopefully interconnected, and woven into and placed near cities.

Urban areas can and must be part of the Half-Earth vision and strategy for it to succeed. What would it mean to be a “Half-Earth City”? No cities have yet used this language or explicitly established half earth as goal (Australian architect Paul Downton was the first to suggest this terminology in a review of Wilson’s book). But cities can and must play a major role: They have the resources and the opportunities to make a difference in biodiversity conservation.

The Significance of Biodiversity

Biodiversity is the variety of life on Earth, the building blocks of functioning ecosystems that provide the natural services on which all life depends, including people. Species, the fundamental units of biodiversity, are in the midst of an extinction crisis, losing ground globally at a rate 1,000 times greater than at any time in human history due to factors like habitat loss and climate change.

How do we stop this? Knowing where species live and the pressures threatening them is paramount in reversing the extinction crisis and maintaining the health of our planet, for ourselves and for future generations. As the impact of humans increasingly encroaches on critical habitats everywhere, determining ‘where’ to protect is just as critical as ‘how much’ to protect.

The Half-Earth Project


In his book, Half-Earth, acclaimed biologist Edward O. Wilson proposed a solution commensurate with the problem: conserve half the Earth’s land and sea to protect the bulk of biodiversity from extinction. Scientists agreed that this proposal was both necessary and possible.

In order to stave off the mass extinction of species, including our own, we must move swiftly to preserve the biodiversity of our planet.
—  E.O. Wilson

Born from his book and built on a solid scientific foundation, the Half-Earth Project is working to conserve half the Earth by protecting sufficient habitat to reverse the species extinction crisis and ensure the long-term health of our planet.

The next question the Half-Earth Project needed to answer was, which Half?

Mapping Half-Earth


Enter Map of Life. Map of Life is a core tool of the Half-Earth Project, which is working to identify and prioritize areas of greatest biodiversity value, and communicate this information in new, dynamic, and engaging ways.

Based out of Yale University and the University of Florida, Map of Life assembles, integrates, and analyzes data on global species distributions. It brings together a wealth of information, assessing information on nearly 100,000 species from hundreds of data sources with multiple data types.

Building on several years of close collaboration with Google, Map of Life leverages Google Cloud Platform services to support biodiversity research, monitoring, education, and decision-making. By leveraging an enormous biodiversity database and a suite of spatial modeling tools, Map of Life is able to capture detailed patterns of species distributions at planetary scale.


Today, the Half-Earth Project Map is using new and existing data and applying cutting-edge capabilities of Google Cloud Platform with the goal of mapping terrestrial, marine, and freshwater species at up to 1 kilometer resolution.

Data Warehousing

For an initial set of analyses we leveraged the PostGIS suite of spatial functions to measure expected species presence by overlaying species range map polygons with a global grid composed of approximately 110 km x 110 km cells.

Outputs from these intersections are stored on Google Cloud Storage and imported to the BigQuery data warehousing service. The speed at which BigQuery can aggregate across large tables and compute metrics has been vital for analyzing large volumes of biodiversity data. This is increasingly important as the Half-Earth Project continues to add new species groups and generates higher resolution predictions of where species occur. Tables currently in the hundreds of millions of rows may scale to billions or trillions of rows as our taxonomic and spatial resolution increases. The low storage cost and transaction-based pricing BigQuery offers allows us to query and aggregate tables of such size without the maintenance and overhead required by a traditional data warehouse solution.


Measuring Biodiversity

One aspect of our work measured biodiversity data in two ways: richness and range rarity.
Richness is the number of species occurring, or expected to occur, within a given area. Richness is the simplest way to measure biodiversity.

Range rarity is a continuous metric of range-restrictedness and crucial for considering species with very small ranges that are often of greatest conservation concern. Range rarity is a close proxy for the irreplaceability of a location when the goal is to conserve as many species as possible.

Determining Goals for Species Protection

Another aspect of our analysis included estimating the amount of land already protected within any given ca. 100km cells grid cell (mentioned above). To map the protected area network, we filtered the World Database of Protected Areas, which became available as an Earth Engine public table asset in 2017, to remove redundant reserves and so called “paper-parks” that lack on-the-ground biodiversity protection. For areas that lack a geometry and only include a point location and reserve area, we generated a polygon by buffering the point provided to the size of the park. We then computed the area protected within each grid cell, and exported the results to Cloud Storage.


While no habitat loss is ideal, species with larger range sizes can generally afford to lose more habitat than those with smaller ranges. Accordingly, we determined individual species “protected” status based on range size and the proportion of their range that is protected. As the amount of protected area increases, the number of species protected also increases.

But what is good for one species group is not necessarily ideal for another, and what is good for the whole of biodiversity may leave small groups vulnerable.

To address this, we leveraged BigQuery’s support for user defined functions (UDF) and computed adequate protection levels with a simple javascript function. Given the ability to apply this test to each species, we ranked grid cells for each species group and tested to see how many species’ global protections met the criteria via a BigQuery window function run across the ranked grid.


Progress toward Half-Earth will be measured as a running total of conservation protections, with the ultimate goal being half the Earth’s land and sea. BigQuery window functions allow this to be computed quickly for each cell in the grid. As we selected breakpoints up to 50% of the Earth’s area, we tested each species with our function to see whether it met its minimum protected area, then counted the number of species that met the criteria for each step in the scenario.

Putting It Together

To ensure rapid map tile delivery to the globe, we generated and exported static tilesets to Cloud Storage using Earth Engine’s feature. This meant exporting compiled data as CSV from BigQuery, which can be re-joined to the grid Shapefile using OGR command line tools and ingested to Earth Engine as a table asset. From there we were able to visualize and explore the data in the Earth Engine code editor and export tiles once we were satisfied with the appearance.


Finally, with our Cloud Storage bucket populated with map tiles and data to drive charts and infographics, the front-end wizards at Vizzuality plugged in to our API to bring it all to life on the Half-Earth Map.

The Half-Earth Map pieces together species distribution data, the protected areas map, and a mask of human activities into a single map useful to scientists, conservationists, communities, decision-makers and anyone interested in biodiversity and the health of our planet.

Nature Divided, Scientists United

Human pressures on the natural world come in many forms. Top among these pressures are large-scale human development projects that impose barriers on species movement.

For example, physical barriers can dissuade animals from accessing food, water, mates, and other critical resources. These barriers can block annual or seasonal migration and dispersal routes. Fragmented populations may suffer from reduced genetic diversity and face greater extinction risks.

In a recent communication to government officials due to be published in the next issue of BioScience, a multitude of scientists and conservationists including E.O. Wilson highlighted these dangers with a specific focus on the wildlife barrier created by the wall being constructed on the border between Mexico and the United States.

“Like any large-scale development,” the authors write in the article spearheaded by Defenders of Wildlife, “construction of the wall and associated infrastructure, such as roads, lights, and operating bases, eliminates or degrades natural vegetation, kills animals directly or through habitat loss, fragments habitats (thereby subdividing populations into smaller, more vulnerable units), reduces habitat connectivity, erodes soils, changes fire regimes, and alters hydrological processes (for example by causing floods).”

The article, “Nature Divided: Scientists United,” highlights the dual concerns that the wall will harm wildlife populations by eliminating, degrading and fragmenting habitats and damage positive binational scientific collaborations. The new barrier threatens many contiguous habitat corridors, including the Sonora Desert, Sky Islands, Big Bend and Lower Rio Grande, and threatens ongoing scientific studies, including a binational aerial census of the endangered Sonoran pronghorn.

The article asks government officials to “mitigate as completely as possible any environmental harm resulting from projects,” including “foregoing physical barriers in places with high ecological sensitivity, such as cross-border corridors or critical habitats for endangered species.” To learn more visit

Protected Areas Under Threat

Human activities are placing growing pressure on the biodiversity of Earth’s lands and seas. According to a study published recently in Science, protected areas – such as national parks, wilderness areas, community conserved areas, and nature reserves – are experiencing declines in their ability to protect nature because of the growth of human activities within them.

Since the 1992 Earth Summit, protected land has roughly doubled in size, with more than 202,000 protected areas now covering almost 15% of terrestrial areas. “The increasing growth and overall extent of protected areas is deservedly celebrated as a conservation success story,” the authors said in the study, “and there is no doubt that well-managed protected areas can preserve biodiversity.”

That’s the good news. The bad news is that “human activities are prevalent across many protected areas, with only 42% of protected land free of any measurable human pressure.” Further, almost 33% of protected lands are under “intense human pressure.”

The primary goal of the various types of protections is to conserve nature: maintain ecological integrity and natural conditions to ensure the protection of species, habitats and the ecological evolutionary process that sustains them. According to the authors, “the presence of these pressures is directly linked to constraints on and declines in biodiversity.”

A new map published with the article highlights the human footprint—combining data on built environments, intensive agriculture, pasture lands, human population density, nighttime lights, roads, railways, and navigable waterways.

As E.O. Wilson said in a recent NY Times editorial, “To effectively manage protected habitats, we must also learn more about all the species of our planet and their interactions within ecosystems.” The Half-Earth Project is mapping the fine distribution of species across the globe to provide scientific leadership regarding the places we can manage for conservation in order to protect the greatest number of species. With this fundamental knowledge, Wilson says, “we have the opportunity to support the most biodiverse places in the world as well as the people who call these paradises home.”

Meet the top 10 news species of 2018, selected by our Global Biodiversity Census partners at SUNY College of Environmental Science and Forestry.

“So many of these species — if we don’t find them, name them and describe them now — will be lost forever. And yet they can teach us so much about the intricacies of ecosystems and the details of evolutionary history. Each of them has found a way to survive against the odds of changing competition, climate and environmental conditions. So each can teach us something really worth knowing as we face an uncertain environmental future ourselves.” – SUNY ESF President Quentin Wheeler.

Renowned Entomologist Edward O. Wilson Receives World Ecology Award

  Two-time Pulitzer Prize-winning entomologist Edward O. Wilson answers questions from the audience after receiving the World Ecology Award from the Whitney R. Harris World Ecology Center at the University of Missouri–St. Louis Friday night in the Anheuser-Busch Theatre at the Saint Louis Zoo. Original story posted in the  USML Daily.  

Two-time Pulitzer Prize-winning entomologist Edward O. Wilson answers questions from the audience after receiving the World Ecology Award from the Whitney R. Harris World Ecology Center at the University of Missouri–St. Louis Friday night in the Anheuser-Busch Theatre at the Saint Louis Zoo. Original story posted in the USML Daily. 

Edward O. Wilson’s work has been lauded the world over with a list of awards – including two Pulitzer Prizes, a National Medal of Science and an International Prize for Biology – too numerous to mention in full.

But the noted biologist, researcher, theorist, naturalist and author seemed humbled as ever to add one more honor Friday night.

On what Mayor Lyda Krewson by proclamation declared Edward O. Wilson Day in the City of St. Louis, Wilson became the 22nd recipient of the World Ecology Award from the Whitney R. Harris World Ecology Center at the University of Missouri–St. Louis.

Interim Director Patricia Parker, the E. Desmond Lee Endowed Professor of Zoological Studies, helped introduce Wilson at the award presentation along with Peter Raven, the president emeritus of the Missouri Botanical Garden.

“I absolutely believe I don’t deserve it, but I guess they have to pass it on to somebody,” Wilson told a packed Anheuser-Busch Theatre inside The Living World at the Saint Louis Zoo. “As far as my career-time friend Peter Raven is concerned – one of the great biologists of our country during his lifetime – and those generous statements he made, I can only characterize them as praise from Caesar.”

Raven, a driving force behind the creation of the Harris Center along with his many other career achievements, is one of the 21 other recipients of the World Ecology Award, first bestowed on John Denver in 1990.

Others include Jacques Cousteau, Jane Goodall, Harrison Ford and Sylvia Earle.

What ties them together is they are all individuals who have raised public awareness of global ecological issues and made significant contributions to environmental protection and biodiversity conservation.

Wilson, the Pellegrino University Research Professor, Emeritus in Entomology for the Department of Organismic and Evolutionary Biology at Harvard University, falls right in line with his predecessors.

The 88-year-old has been called the “father of biodiversity” and has earned acclaim for his work researching the behavior of ants. He is a two-time winner of the Pulitzer Prize for General Nonfiction for “On Human Nature” in 1979 and “The Ants” in 1991, and has been a pioneer at preserving and protecting the biodiversity of the planet.

He made it the central theme of his acceptance speech.

The proclamation from Mayor Lyda Krewson declared April 20, 2018, “Edward O. Wilson Day in the City of St. Louis”.

“I think that we should recognize that there are two, not just one, environmental crises as commonly perceived,” Wilson said. “The first, of course, is climate change. … But the second crisis, and the one the subject of this talk and this meeting here tonight and substantially the focus of the Harris Center program – a big part of it – is the accelerating reduction of natural biodiversity worldwide, which is beginning to destroy natural support systems. If we don’t halt that, and even if the climate is stabilized, the mass extinction of species on Earth will turn Earth into a literal and not just a metaphorical spaceship with the vital environment that we inherited on it controlled no longer by nature but by people.”

He made a case for the Half Earth Project he first championed in his 2016 book “Half-Earth: Our Planet’s Fight for Life.”

The awards presentation – and dinner gala that preceded it – came at the end of a packed day in St. Louis for Wilson. He toured UMSL’s Harris Center partners – the Missouri Botanical Garden and Saint Louis Zoo – and had lunch with UMSL graduate students in biology whose training and research in ecology and conservation are supported by the center.

Proceeds from the gala dinner go to aid those efforts. The Harris Center has helped support more than 275 master’s and Ph.D. graduates since it began as the International Center for Tropical Ecology in 1990. They’ve come from 38 countries and returned to work in more than 30 countries in academic, governmental and nongovernmental positions connected to ecology and biodiversity conservation.

“I think it’s an honor to our town,” community volunteer and Harris Center Leadership Council chair Liz de Laperouse said at the end of the evening. “It’s an honor to UMSL and an honor to the program, the Harris Center, that he would come. He doesn’t like to travel anymore. He came here for these students, so it’s a great tribute to all of us.”

Wild Dogs Return to Gorongosa National Park

Mozambique, Africa – With only around 6,600 Wild Dogs left in Africa, this iconic species is one of the Continent’s most at-risk carnivores, and is listed by the IUCN as ‘Endangered’. Urgent action is needed to save them. A key conservation strategy is to reintroduce Wild Dogs to viable ecosystems where they once ranged. The Endangered Wildlife Trust (EWT), a champion of wildlife conservation in Africa, and Gorongosa National Park are excited to announce the completion of a historic translocation of Wild Dogs from South Africa to Mozambique.

On April 16, 2018, in a bold and innovative move to reverse the fate of Wild Dogs in southern Africa, this new and exciting partnership between the EWT and Gorongosa National Park ensured the reintroduction of the Park’s first pack of Wild Dogs in decades. This is a landmark occasion, as Wild Dogs have not been reintroduced to any park, protected area, game reserve or other space in the history of Mozambique. This truly represents conservation in action – an ambitious venture to restore Wild Dogs to an incredible ecosystem.

Wild Dogs have disappeared from much of their former range in Mozambique, and Gorongosa lost their population during the 1977-1992 Civil War. Today, Gorongosa is Mozambique's flagship natural area - the heart of a region where the Government of Mozambique has teamed with the Carr Foundation on a long-term, 25-year restoration project to rehabilitate a vast and diverse natural ecosystem. In just over a decade, many species in the park have made a strong comeback, including tens of thousands of herbivores. The natural next step is the return of large carnivores.

Wild Dogs from South Africa’s EWT-managed metapopulation were used as founder individuals in this reintroduction. The metapopulation, a group of managed national parks and reserves, is the largest population of Wild Dogs in South Africa, numbering 250 individuals in 28 packs (more than that of the Kruger National Park). This population has increased dramatically over the last 20 years and has ensured the increase in Wild Dog range in South Africa by 25% and numbers by 100%.

Males from uMkhuze Game Reserve in KwaZulu-Natal (KZN) that dispersed from their pack in late 2016 and free-roaming KZN females were earmarked for reintroduction. The EWT, along with local partners Ezemvelo KZN Wildlife (EKZNW), the KZN state veterinary department, WildlifeACT, Maremani Game Reserve, LEDET, and the Bateleurs, caught the two unrelated groups of Wild Dogs and brought them together to bond in a boma at Phongola Nature Reserve in KZN in South Africa. The pack was fitted with GPS collars and VHF collars to allow for close monitoring once released. All individuals were vaccinated against canine distemper and rabies, as infectious diseases are a big threat to Wild Dogs.

The new pack was moved from the Phongola boma to Gorongosa by air transfer. The trip from Phongola to Gorongosa is a two-day drive through long, hot and difficult roads, making air transport with the Bateleurs the safer option, thanks to a combination of safe drugs administered by a qualified veterinarian from EKZNW. The sedated pack was under the experienced guard of both the vet and the EWT’s Wild Dog Metapopulation Coordinator. Upon arrival, the sleeping males and females were bonded together in a novel way, called the olfactory acclimatisation technique. The bonded pack is being held in the newly constructed boma in Gorongosa for six to eight weeks before being released. This is to allow the males and females to become accustomed to one another and get habituated to the local area. During this time, Gorongosa’s Carnivore Conservation Team will monitor the health and status of the pack in the boma before release. The EWT will work closely with the Gorongosa team to train a new generation of Mozambican vets and ecologists in Wild Dog recovery and management.

Gorongosa National Park has been described as one of the most diverse parks on Earth, covering a vast expanse of 400,000 hectares. In recent years, the Gorongosa Project, with the support of Mozambique’s National Administration of Conservation Areas (ANAC), has ensured the protection of a recovering population of Lions in this system, successfully reduced key threats, and seen the Park recognised as one of National Geographic's ‘Last Wild Places.’ It is therefore truly thrilling to take this first, big step on a momentous journey to restore Wild Dogs to this part of their native range.

This work is made possible by EWT funders, Richard Bosman and Land Rover Centurion, Gorongosa Project funders, Gorongosa National Park, Oak Foundation, and ZooBoise.

Gorongosa National Park is home to the E.O. Wilson Biodiversity Laboratory. The center’s main goals are to document Gorongosa’s vast biological richness, manage its restoration, and train a new cadre of local conservationists, educators, and scientists. 

From Backyard Ant-Watching to World Ecology Award: A Conversation with E.O. Wilson

“From Backyard Ant-Watching to World Ecology Award: A Conversation with E.O. Wilson”
By Evie Hemphill
This article originally appeared on the website for St. Louis Public Radio, April 17, 2018

Edward O. Wilson’s long career has been marked by enormous contributions to the field of biology, with an impact on global conservation efforts that is difficult to overstate. All of it grew out of his close attention years ago to something relatively small: the behavior of ants.

Wilson recalled one of his earliest interactions with the insects, a memory from his boyhood in northern Alabama, on Tuesday’s St. Louis on the Air in conversation with host Don Marsh.

“In our backyard I saw this stream of ants,” said the now 88-year-old Harvard scholar, who is headed to the St. Louis Zoo this week to receive an award from the Whitney R. Harris World Ecology Center at the University of Missouri-St. Louis. “It turns out that there were tens of thousands of them in a single colony, marching five to ten across in perfect formation – or near perfect formation for an insect – across the yard, all in one direction.

“I followed them over a back fence into the next yard … the column continued on across that yard and out into a street, across the street,” Wilson went on, “and then into a patch of woodland where they disappeared and I couldn’t follow them. And I soon learned that what I was seeing was the march of the army ants. Army ants just get that far north. You can find big army ants – with millions of workers – in the tropics, and I was later to see those many times.”

With about 15,000 species of ants in existence on the planet, the creatures would soon capture Wilson’s interest for a lifetime. And they make up just a fraction of the roughly 10 million species, as Wilson estimated during the show, that currently call Earth home.

“We’ve just begun to explore life on this planet,” Wilson said, adding that such biodiversity is at great risk now with species going extinct “somewhere between 100 and 1,000 times faster than before the coming and the spread of humanity.”

“Probably closer to 100 times,” he noted, “but at the same time accelerating higher and higher. By the end of the century, it’s easy to predict that unless something is done, half of earth’s living diversity will be gone.”

Wilson, a two-time Pulitzer Prize winner, offers ideas for addressing that looming reality in his book “Half-Earth: Our Planet’s Fight for Life.” He is also beginning work on another volume to be titled “Tales from the Ant World.”

An only child who grew up in “the wilds of Alabama,” Wilson said, he developed an affection for nature at an early age, collecting butterflies and reading “every issue of National Geographic” that he could get his hands on.

He dreamt of “someday going on great trips into the jungles” and discovering new kinds of animals.

“A boyhood dream, except that I was able to live that dream,” Wilson said. “[By high school] I thought that maybe I could become a ranger in a park, maybe I could become an entomologist studying insects, the kind who advises farmers on how to control pests and so on. And somehow I thought I could make a living, when I grew up, in the outdoors. The big thing was to never, ever have to come in from the outdoors.”

By the time he headed to college at the University of Alabama, he had decided on ants as his research focus.

Wilson first joined Harvard’s faculty in 1956 and introduced the concept of sociobiology, the systematic study of the biological basis of social behavior in all kinds of organisms, nearly five decades ago. In 1995 he was named among the 25 most influential Americans by TIME.

The World Ecology Award that the Harris Center will bestow on Wilson this Friday, April 20, recognizes individuals who have raised public awareness of global ecological issues and made significant contributions to environmental protection and biodiversity conservation.

Previous recipients of the award include marine biologist Sylvia Earle (2016), Albert II, Prince of Monaco (2013), Harrison Ford (2002), Jane Goodall (1999) and John Denver (1990), among others.

For Endangered Florida Tree, How Far to Go to Save a Species?

The Florida torreya is North America’s most endangered conifer, with less than one percent of its population remaining. Now, scientists are mounting a last-ditch effort to save the torreya and are considering using new gene-editing technologies to protect it. 

By Janet Marinelli, March 27, 2018

Edward O. Wilson clambered partway down a slope in the Florida Panhandle, aided by a park ranger and trailed by a few dozen scientists, conservationists, and local landowners. The group had gathered in Torreya State Park, a landscape of dazzling botanical diversity along the upper Apalachicola River, as part of a whirlwind two-day meeting early this month to ponder the fate of its most storied tree. As the wind gusted through leafless branches, the lanky, white-haired Wilson, at 88 years of age still one of the most brilliant biologists of his generation, planted a seedling of the Florida torreya, North America’s most endangered conifer.

Wilson first visited the Apalachicola bluffs in 1957, as a self-described “young guy” with a new position at Harvard University, on an ant-collecting trip in Florida. “I came here,” he recounted, “the way you would go to Paris to visit a cathedral. I just had to see the torreya.” The trees had already begun their steep decline.

More than 60 years later Wilson was back. This time he declared the site “is not only a cathedral, but also a battleground at which one of the greatest events in American history will take place” — a turning point, as he sees it, in the planetary struggle to slow biodiversity loss.

Last spring, another “young guy” was at Torreya State Park on a camping trip with his lab. University of Florida forest pathologist Jason Smith “couldn’t believe how much worse the torreyas were” than when he had seen them the year before. “The population was crashing.” Smith, who has reddish brown hair and a bundle of energy, decided to assemble a team to reflect on the meaning of the species’ imminent demise, to catalog the “torreya tree of life” — all living things with which it associates in the wild — and to plan a last-ditch effort to save it.

“This is a now or never moment for the species,” he says.

While the massive wildfires and tree die-offs out West have gotten most of the press in recent years, the Eastern forests are also in crisis. An increasing number of the region’s iconic native trees are plagued by pests and pathogens introduced from abroad. This has researchers scrambling to find genes that can help impart resistance, and to breed them into the ailing trees. Because classical crossbreeding takes decades — perhaps too long for a critically endangered species like the torreya — options once unimaginable as conservation measures are now being considered, including the new group of gene-editing technologies called CRISPR that has taken the biotech world by storm.

The growing forest health crisis is forcing scientists, conservationists, and the public to answer some of conservation biology’s thorniest questions. Will we be able to use biotechnologies on the frontier of plant science to rescue imperiled species? Should we? And when so many species are at risk, does it make sense to go to extraordinary lengths to save a tree like the Florida torreya that has a tiny historical range and no commercial value?

Not long ago, Torreya taxifolia, as the tree is technically known, cast an evergreen veil over its historical habitat, a short stretch of sharp-sloped ravines called steepheads, some of which plunge at inclines close to 45 degrees — enough to induce wooziness in Floridians accustomed to pancake-flat terrain. In a vast biotic convergence, the tree mingled with massive southern magnolias, fan-leafed palmettos and other subtropical plants as well as northern denizens such as beech, hickory, and maple driven to the Panhandle over the eons by glaciers. As many as 650,000 torreyas once lived here.

In the 1800s, local inhabitants used the conifer to make fence posts and shingles and to fuel the steamboats that plied the Apalachicola. Sometime around World War II, the remaining trees were attacked by a fungal blight and began their catastrophic dieback. The Florida torreya has been trapped in a purgatory-like adolescence ever since. Saplings sprout from old roots, only to succumb to the disease before they are mature enough to reproduce.

At the meeting earlier this month, Rob Nicholson, collections manager at Wellesley College Botanic Garden, told the assembled group about the torreya’s tangled history with humans. In the words of Nicholson, who journeyed to the Apalachicola bluffs from Harvard’s Arnold Arboretum in 1989 to help survey the trees and collect cuttings, the torreya was once “a beautiful, shaggy pyramid, some fifty feet high and cloaked with glossy evergreen needles.” The species, he wrote at the time in Natural Historymagazine, “was going extinct before our eyes.”

Today, said Emily Coffey, vice president of conservation and research at the Atlanta Botanical Garden, “only 0.22 percent of the population is left.” Since 1990, her organization has led the effort to create a life support system for the species by safeguarding it in cultivation. They have been so successful that the largest population of Florida torreyas, more than 800 specimens, now resides not in the steepheads, but rather a modern-day ark of pots, propagation beds, and experimental plantings at a handful of sites in northern Georgia. The Atlanta Botanical Garden and partner organizations have managed to preserve much of the species’ genetic diversity, protecting some 441 genetically distinct individuals in cultivation. The idea is to use the plants to restore the species in the wild.

Safeguarding the torreya has been staggeringly complex. Unlike most plants, the tree has so-called recalcitrant seeds, which cannot be preserved in conventional seed banks because they can’t survive drying. This necessitated the development of a tissue-culture system for the species called somatic embryogenesis. Embryos are surgically removed from fully developed seeds, then cultured in vitro to encourage the formation of multiple embryos. These can be safely preserved in a new cryogenic storage unit obtained by Atlanta Botanical Garden, in which the resulting plantlets are coaxed into a state of suspended animation at -321° Fahrenheit in liquid nitrogen.

Ultimately, however, saving the torreya in its steephead home will require outsmarting the pathogen that is killing it. Although a number of fungal diseases were found to be afflicting the trees to some extent, the lethal pathogen remained elusive. But in 2010, Jason Smith discovered the culprit, Fusarium torreyae, a fungal pathogen new to science. Evidence suggests that it was introduced from China. If no action is taken, the tree will go extinct along the Apalachicola, “probably in 50 years,” Smith says.

For the past two decades, the Florida torreya has been not only a symbol of fungal pathogens run amok, but also a poster child for assisted migration, the deliberate movement of a species suffering from climate change to more favorable habitat outside its historical range. The tree is widely believed to be an Ice Age relict that once grew farther north but became trapped in the steepheads when the last glacier retreated. In fact, torreyas planted as far north as Ohio are producing seed. However, a study by one of Smith’s graduate students suggests that Fusarium torreyae may also be deadly to a number of trees that are native to the southern Appalachians. “It could be that climate change is stressing the torreyas,” says Smith, “making them even more susceptible to the disease.” But in order to prevent the spread of the pathogen, he says, “we have to deal with the disease first.” 

At the meeting early this month, Dana Nelson, a forest geneticist at the U.S. Forest Service Southern Research Station in Kentucky, reeled off a long list of Eastern trees suffering from exotic bugs and blights. One of them, the emerald ash borer, an iridescent green beetle from northeastern Asia, has killed hundreds of millions of ash trees, including virtually all the ashes in Michigan, where it was discovered in 2002. In the Appalachians, vast tracts of Eastern and Carolina hemlock have been decimated by the hemlock woolly adelgid, a tiny, fuzzy white insect native to East Asia.

One of the first trees to succumb to an introduced blight was the American chestnut, which once painted forests from Maine to Mississippi snowy white when it bloomed in spring. Around the turn of the 20th century, the species was struck by a fungal pathogen imported from Asia. Within 50 years, billions of trees were killed. A forest dominant that once grew up to ten feet wide and soared 100 feet to the top of the forest canopy, American chestnut now clings to life, like the Florida torreya, by sending up spindly stump sprouts.

Smith hopes to use the quest to save the American chestnut as a model for the imperiled torreya. When it was his turn to address the meeting, Jared Westbrook, a forest geneticist who became director of science at the American Chestnut Foundation in 2015, chronicled the group’s 90-year struggle to breed resistance into the species.

Efforts began with traditional crossbreeding of American chestnut with its close relative, the Chinese chestnut, which evolved with the pathogen and finds it a minor nuisance. The painfully slow process of back-crossing the resulting hybrids with pure American chestnut over six generations to remove as many foreign genes as possible has yielded trees that are 94 percent American chestnut. “Right now,” said Westbrook, “the trees have intermediate levels of resistance.”

To ramp up the resistance, the foundation hopes to breed these trees with a transgenic chestnut developed at the State University of New York’s College of Environmental Science and Forestry. To create the transgenic variety, one wheat gene was inserted into the species’ gene pool to disarm the fungus. In the words of lead researcher William Powell, the result is “a plant that is 99.9997 percent American chestnut.” Breeding must wait until the transgenic chestnut completes its lengthy federal regulatory review.

Although few scientists fear that the transgenic chestnut would result in a “super tree” capable of overrunning Eastern forests, the public is still jittery about genetic engineering. An impartial committee has been convened by the National Academy of Sciences to study “the potential of biotechnology to address forest health.” Its report is expected at the end of this year.

In part to sidestep the controversy, Smith is hoping to use CRISPR to, in his words, “toggle up” disease resistance in the Florida torreya’s own genes. Given the tree’s imminent extinction along the Apalachicola, he says, “regular breeding is too slow.” CRISPR exploits a natural ability of bacterial immune systems to identify and disable invading viruses. Scientists create short RNA sequences that attach to corresponding sequences in the receiving species’ DNA. This molecular guidance system is paired with an enzyme that originally was designed to snip the DNA, “knocking out” a targeted gene. Using modified versions of the enzyme, it is now possible to activate or increase gene expression.

Just a few years ago, when CRISPR appeared on the biotech scene, it was a messy business. Scientists whacked DNA with all the finesse of a molecular machete, often triggering not just the desired snips, but a hodgepodge of unintended genetic changes, dubbed “off-target effects.” Yet as researchers around the world have continued to fine-tune the technology, fears of CRISPR gone out of control have begun to fade. The technology is already being used to confer crops with everything from drought resistance to longer shelf life.

Still, an easy techno-fix for Florida torreya is unlikely anytime soon. John Davis, associate dean for research at the University of Florida and a member of the steering committee of the Forest Health Initiative, points out that if by chance there is natural resistance in the Florida torreya, plant production for breeding via seed, cuttings, or tissue culture would need to vastly increase. What’s more, CRISPR has never before been used to restore a tree species’ fitness for life in the forest. “This would require more research,” he says.

As the meeting disbanded, Smith and other researchers resolved to begin the hunt for resistance genes. The horticulturists and scientists responsible for safeguarding the species in cultivation said their highest priority is continuing the search for additional genetic diversity in as-yet-unidentified torreyas on private property. Local community members declared they would work with their neighbors to facilitate the search for these remaining trees. Because unique species of fungi, which, in Smith’s words, “rule forest trees, both in life and in death,” are often associated with a particular tree, University of Minnesota forest pathologists left with vials of soil and dead and living wood. They will analyze the contents to determine whether “an extinction vortex” is underway within the torreya’s ecological community.

As Nicholson pointed out, the genus Torreya is one of the most ancient groups of plants still in existence, dating back 175 million years to the mid-Jurassic period. But four of the six remaining Torreya species, including the Florida native’s closest relative, California nutmeg, are on the IUCN’s Red List of threatened species and may not survive modernity.   

“Every scrap of biological diversity is priceless, to be learned and cherished, and never to be surrendered without a struggle,” Wilson wrote in his 1992 book The Diversity of Life. At the meeting, he pledged to dedicate his remaining years to raising the global extinction crisis “to the same level of urgency as slowing climate change.”

“As biodiversity continues to hemorrhage all around us,” Wilson said, “we face a momentous moral decision that can be put in the form of a question: What kind of a species are we to treat the rest of life so cheaply?” This, he added, “is not only a moral issue but an issue of survival.” He then posed another question: “What will future generations think about how we have acted so carelessly?”

A “Moon Shot” to Protect Earth’s Species

This article originally was published in The Harvard Gazette, March 29, 2018.
By Alvin Powell.

Biologist E.O. Wilson and former National Park Service director envision massive conservation effort to stem extinction

The extinction of our swimming, trotting, slithering, and flying companions on Earth is a building global disaster on a par with climate change, but one that has a solution, according to noted biologist Edward O. Wilson.

Wilson, Harvard’s Pellegrino University Professor emeritus, says that setting aside half of the Earth’s land and half of its oceans would be enough to save 85 percent of species, which are becoming extinct at a rate between 100 and 1,000 times the rate before humans.

Wilson, who spoke at the Harvard Kennedy School’s (HKS) John F. Kennedy Jr. Forum on Wednesday, acknowledged that setting aside that much land would be no easy feat. He also said it couldn’t just be any land, but would need to have key features, such as high biodiversity, and land corridors to protect ages-old migration routes and connect preserves, parks, and other places set aside for wildlife.

“People want a ‘moon shot,’ and this is a moon shot of conservation that we can achieve,” Wilson said. “We can do it, and we can begin doing it now.”

Wilson made his comments during a panel discussion, “Climate Change, Biodiversity, and the Future of Conservation in America,” that also included Jonathan Jarvis, director of the National Park Service during the Obama administration. The event was moderated by HKS’s Linda Bilmes, the Daniel Patrick Moynihan Senior Lecturer in Public Policy and a member of the National Park Service Advisory Board.

Though Jarvis agreed such a massive task would be difficult, he also said that the current U.S. administration’s negative stance on the environment has created an opportunity to mobilize public support and make common cause among groups concerned about other policy areas, such as women’s rights, support for science, gun control, and immigration issues.

“There’s nothing like a crisis to galvanize public support,” Jarvis said. “We’re in this perfect moment in time, where there is clearly an assault on the environment … and the opportunity is to bridge what had been separation amongst the environmental justice, social justice, classic environmental, public health, municipalities, and the hunting and fishing crowds.”

Jarvis said that just 12 percent of U.S. land currently has some sort of conservation status, but he highlighted efforts underway to collaboratively manage lands, as in the Northern Rocky Mountains, to keep it and the creatures there healthy. Another example is the work to conserve a Wyoming wildlife corridor called the Path of the Pronghorn, a 200-mile migration route, parts of which are threatened by development, used by pronghorn antelope during their annual migrations.

Further, Jarvis said, conservation land doesn’t necessarily mean land entirely free of human impact. While he and Wilson agreed that some wildlands and ocean preserves should be maintained without human intrusion, many places can support some level of human activity. When considering the conservation status of an area, Jarvis said an effective initial step is to talk with the people using that land, particularly if they depend on it for their livelihoods. An eventual conservation plan should take their concerns into account, he said, and, though a vocal, anti-conservation core may remain opposed, most objections fade over time.

Both Jarvis and Wilson traced the fondness for wild places back to humanity’s deep roots and millennia spent living outdoors. That life instilled in people a deep appreciation for nature, which Wilson called “the love of the home that one forms in the natural world.” It has only been in recent generations that people have “come inside,” Jarvis said, and a core part of many people retains that appreciation for nature.

“I can take any individual … to the rim of the Grand Canyon or to the High Sierras to see the Milky Way or to stand beneath the giant sequoias and they are moved,” Jarvis said.

Aiding efforts, Jarvis said, is that the health benefits of nature are becoming recognized to the extent that doctors are prescribing that people walk outside. In response to a question from the audience about how to boost the acreage of wild places, Wilson said people can help even when selecting plants for landscaping by choosing native species instead of exotic ornamentals, which not only can be harmful when their seeds spread into the environment, but also sometimes offer no sustenance for native insects, on which birds and other animals depend.

And, though preservation of large, wild places is important in any conservation scheme, the increasingly urban population’s love of the outdoors can be fed by ensuring neighborhoods have parks and other green spaces. National parks, Jarvis said, should be managed for the whole population, not just for the middle and wealthy classes. That’s why, he said, a proposed hike in park entry fees is a bad idea.

When asked how the next generation can help, Jarvis suggested that young people vote for conservation-minded leaders and run for office themselves.

Wilson said an enormous amount of work remains to categorize and understand life on Earth, work that will inform which lands and ocean areas are most critical to preserve. Though 2 million species have been identified so far, scientists estimate another 8 million remain to be described, Wilson said, so there is plenty of work for the next generation of biologists.

Return of Leopard to Gorongosa National Park in Mozambique

Mozambique, Africa – Gorongosa National Park is Mozambique’s flagship natural area. The Park is the heart of a region where the Government of Mozambique teamed with the Carr Foundation on a long-term plan to bring back-to-life a vast and diverse natural ecosystem. Park programs also benefit the surrounding human communities – a vision for a landscape where both wilderness and
people thrive.

Today, many species in the Park have made a strong comeback. Only a short drive from the main lodge in Chitengo Camp one becomes immersed in herds of impala, nyala, kudu, waterbuck, and elephant. These herbivores are the foundational species upon which a recovering ecosystem is built, and quick to follow-suit in such a finely-tuned ecosystem would be their natural predators. Return of large carnivores here – the lions and leopards, hyaena and painted dogs – would be a strong indicator of ecological balance and a healthy ecosystem.

Mysteriously, however, despite a recovering lion population, abundant prey and suitable habitat, for more than a decade, Africa’s most elusive cat – the leopard – has shown little sign of existing in the Park. Not a single leopard had been sighted by any ranger, safari guide, remote cameratrap, or scientific expedition since 2008.

But then the unexpected happened.

  Image captured by Zander Beetge to whom we are very grateful

Image captured by Zander Beetge to whom we are very grateful

On March 29th 2018, only 20 minutes from the Park’s main lodge, nature guide Leonardo Felix Mandevo of Gorongosa National Park was heading back to camp for the night when he flashed his spotlight through a break in palm thickets and the beam landed squarely on a male leopard. The leopard casually crossed the main road in front of a disbelieving group of tourists (Zander Beetge, Marlina Moreno and Tero Makinen) and guides (Leonardo Mandevo and Richard Lusinga). In that single flash of a light, history was made and a species not seen by anyone in the Park for over a decade was officially back on the map.

“Seeing is believing. Gorongosa is healthy. My joy doubled when I saw the happiness of our Mozambican guides who spotted the leopard. This ecosystem is their cultural and biological heritage.” said Greg Carr, who has co-managed the Gorongosa Project since 2008. Mandevo was the first to spot the leopard. He was born in Vila Gorongosa, a local community, and he co-leads safaris in to the Park daily for a growing market of adventure tourists who visit Gorongosa. “It’s an honor to have seen the leopard. I’ve been here for three years and we are always trying to spot one. When I finally did I almost didn’t believe my eyes. I’ve very happy!” said Mandevo.

Big cats survive today in Africa’s protected areas because of boots-on-the-ground work by local rangers to secure their habitats. Focused missions by the Park’s trained team of 230 rangers – all Mozambican – has, in no uncertain terms, yielded tangible results. Ranger teams patrol the Park diligently, 365 days per year, covering thousands of kilometers as they sweep over a rugged wilderness landscape that few people get to experience in its entirety. Their work has led to a 94% decline in snaring of the Park’s lions and 60% decline in poaching pressure, in just two years.

Dr. Rui Branco, the Park’s Mozambican Head of Law-Enforcement, who oversees the rangers said: “Knowing the high stakes for leopard recovery, we focused intensively on securing a key corridor along the eastern boundary of the Park that adjoins vast forestry concessions and the Marromeu Reserve. We know remnant populations still exist there. This corridor is critical for the leopard’s survival in this region. Today we have living proof of why this work is important.”

Over the coming weeks, rangers and the big cat monitoring team will continue tracking the leopard to try to understand more about where he is heading and if he is with leopard friends in the area. “When one arrives, more are likely to follow.” said Paola Bouley, Associate Director of a carnivore recovery unit supported by National Geographic’s Big Cat Initiative. “This is a male in great condition. Young males like this are the explorers who range further afield as they seek out new territories and mates, pushing the boundaries. People always ask us if we have leopards in the Park, well finally we can say ‘yes we do’.

More background: Ecosystems across the planet have evolved to accommodate both robust prey populations as well as the top carnivore species that depend on them for survival. Unfortunately, many populations of large carnivores have suffered large-scale declines: habitat loss and loss of prey; a growing illegal trade in their body parts fueled by traditional use and Eastern markets; and, conflict with humans and their livestock are all contributors. In recognition of their fragile futures, in 2016 the US listed the African lion on the Endangered Species Act. Shortly thereafter scientists demonstrated that leopards may soon follow suit if protections aren’t strengthened. Even a species as tenacious, secretive and adaptable to human-dominated environments as the leopard is simply no longer secure.

In remote corners of wild Africa—such as Central Mozambique–some of these species persist. They have a strong chance of survival if they are the focus of intensive recovery efforts such as the program in Gorongosa. The Gorongosa Project has recently signed strategic partnerships with landowners adjacent to the Park to secure and protect key wildlife corridors and to ensure that large, connected landscapes are part of this region’s future.

The Gorongosa Project integrates conservation and human development with the understanding that a healthy ecosystem will benefit human beings, who in turn will be motivated to support Gorongosa Park objectives. For more general information, visit Gorongosa National Park – Overview

Re: Ghana’s responsibility to protect the globally important Atewa Forest

Your Excellency,

I am writing to draw your attention to global concerns for the future of the Atewa Forest in Ghana, prompted by news that the hills on which the forest is located are to be mined for bauxite.

As I am sure you are well aware, the Atewa Forest is of exceptional biological importance being the finest example of Upland Evergreen Forest in the Upper Guinean Forest region (from Ghana west to Sierra Leone). Only about 5% of the Upper Guinean forest now remains, so sites like Atewa Forest are of global importance. Atewa Forest is so exceptional that it is listed amongst 38 places around the world that I highlight in my book Half Earth: Our Planet's Fight for Life as the most important places on earth that humanity should set aside for nature. It therefore worries me greatly that such a special site should be considered for mineral exploitation.

The reason for Atewa’s great biological importance lies in the high diversity of species and the high level of rarity of many species that are found in the forest. Atewa is home to many thousands of species of which over 100 are at either threatened or near-threatened with extinction according to the International Union for Conservation of Nature (IUCN). These include 11 mammal species, 13 birds, 12 amphibians, 1 reptile, 4 fish, 3 butterflies and no less than 59 species of plant. Three of these species are Critically Endangered with extinction, the highest level of threat that can be assigned by IUCN. The White-naped Mangabey Cercocebus lunulatus is a Critically Endangered primate whose global range is almost entirely within Ghana and which is already the subject of intensive conservation breeding programs at zoos in Ghana and around the world. It would be a great setback to global efforts to save this species from extinction if a site that currently protects this species is lost. The Togo Slippery Frog Conraua derooi which is also Critically Endangered is found only in Atewa Forest and in the Togo-Volta hills. The population in Atewa is about to be described by scientists as a new species distinct from the population in Togo-Volta hills. Two species of butterfly—Mylothis atewa and Anthene helpsi—are found in Atewa Forest and nowhere else in the world.

The relatively high altitude of Atewa Forest causes a distinctive type of vegetation to grow that is extremely rare in Ghana but very rich in species. Over 1,000 species of plants, 230 species of birds and at least 50 species of mammals have been recorded in Atewa Forest. The forest has over 570 species of butterflies recorded and another 138 are expected to occur which would make it the richest forest for butterflies in West Africa.

In recent months, careful work led by A Rocha with support from IUCN Netherlands, has demonstrated the forest’s enormous importance to the water supply of five million people in Accra. In their report to the government of Ghana The Economics of the Atewa Forest Range, Ghana (, they provide a compelling economic case for protecting the forest which when combined with its biological importance makes a strong argument to designate Atewa Forest as a National Park.

The extraction of bauxite will undoubtedly require the forest to be removed since the deposits are only within the top few meters of the horizon and spread over a wide area. There is no low impact technology that can access these sorts of deposits without stripping away the surface. The resulting landscape will be impossible to restore to its former condition because the organic layer will be removed during the mining and it would probably take centuries for the lost flora and fauna to be re-established if they are not entirely extinct. I am also very concerned about the presence of an alumina processing plant in such a sensitive landscape. The highly caustic “red mud” that is a by-product of the Bayer refinement process is notoriously hard to store and lethal if it escapes. This poses a dreadful risk to the Atewa landscape and its critical water supplies.

The alternative vision for Atewa Forest to declare it a National Park would be a progressive, commendable and enduringly positive legacy for your Government in stark contrast to the loss that would be experienced should the hills be mined. Protecting Atewa Forest in this way would deliver on Ghana’s commitments to the Convention on Biological Diversity (CBD) and to the Sustainable Development Goals. In particular, I would like to remind you of CBD Aichi Biodiversity Target 12 to which Ghana, along with all other Parties to the CBD, is formally committed: By 2020 the extinction of known threatened species has been prevented and their conservation status, particularly of those most in decline, has been improved and sustained. Ghana, along will all member states of the United Nations, is also committed to Sustainable Development Goal 15, target 5, which states: Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species. I believe that mining of bauxite in Atewa Forest is inconsistent with Ghana’s existing international commitments.

On the other hand, establishing a new National Park is an option with great public support amongst the forest-edge communities who are so dependent on the forest. A new National Park at Atewa Forest can deliver sustainable jobs and livelihoods for many people and as part of a living landscape can provide new economic opportunities. Your Government’s decisive action to bring an end to the menace of galamsey has already demonstrated your commitment to the environment and has had a direct benefit for Atewa Forest. I urge you then to choose a sustainable and positive future for Atewa Forest and set it aside from mining plans. I believe that this is not only the right thing to do, but would also be a tremendous example to other countries that might be tempted to compromise on long-term biodiversity commitments to obtain short term economic benefits.

Sincerely yours,

Edward O. Wilson

A Silent Reminder: the Interwoven Effects of Climate Change


From the windswept bow of the R/V Laurence M. Gould, I watch as a dozen chinstrap penguins porpoise across the surface of the icy sea. The small black-and-white penguins torpedo along, moving rhythmically back and forth between air and water. Travel made easier. What a remarkable twist of evolution to take advantage of air’s lesser density.

As I watch, I’m reminded I’ll soon see the Adélie penguin colonies near Palmer Station, the tiny research station that is home away from home for me along the western Antarctic Peninsula. Adélie colonies on the islands near Palmer Station have become iconic symbols of how human-induced climate change is now threatening the biodiversity of Antarctic seas. Once numbering 15,000 mating pairs, over the past 45 years the populations on these islands have plummeted ninety percent, now a paltry 1,500 pairs.

In my book Lost Antarctica, I titled my chapter on these Adélies “Ghost Rookeries,” a heart-wrenching reminder of their ongoing fate. Without addressing global climate change, Adélies will continue to suffer the unseasonable snow storms that bury their eggs, and the loss of krill that provide a key source of their nourishment. (Actor Harrison Ford, with help from the E.O. Wilson Biodiversity Foundation, helped bring wider attention to this chapter’s prose by narrating a short video outlining the Adélie’s plight.)

And so it is that even in this remote area of the globe, in seemingly pristine areas so far from human populations, there are clear signs of our impact on the natural world.


Though seemingly isolated, Antarctica and the surrounding seas that are home to the Adélie and the krill that feed them are intricately connected to other ecosystems around the world. The salty, cold waters that flow clockwise around Antarctica sink deep in to the ocean, creating a conveyor belt of currents that carry oceanic heat to the ocean basins of the Atlantic, Indian, and Pacific, and collectively influencing the global climate system. As Antarctica is increasingly influenced by climate change so, in turn, are climates elsewhere. Changing ecosystems follow suit, disrupting linkages between predator and prey: Adélies and krill, caribou and grasses; sea lions and anchovies, the list is extensive.

We are now in the midst of an extinction crisis, where species are going extinct at rates 1,000 times higher than any time in human history. So what can we do?

When it comes to championing global biodiversity, nobody has a deeper commitment to the cause than my friend and colleague, E.O. Wilson.

In his recent book Half-Earth, Wilson says that we must understand species populations to understand where we need to protect and manage land and sea for conservation. Every species has a role in the broader ecosystem. Every ecosystem has a place in the natural world.

As species increasingly go extinct, ecosystems falter, and the health of our natural world is threatened. Therefore, species are the fundamental level of study that must drive conservation priorities.

The Half-Earth Project, led by his Foundation, is doing this work, mapping global biodiversity, helping identify conservation priorities and leading efforts to fill in gaps in information.

Last year, my field studies to build our understanding of the Adélie and the Antarctic ecosystem didn’t permit me to attend Half Earth Day held at National the Geographic headquarters in Washington, DC. From all reports, the conference was a stunning success. Scientists and conservationists from around the globe agreed that Ed’s vision for the preservation of half the Earth to ensure sufficient habitat to sustain biodiversity and a heathy planet was both necessary and achievable. Half-Earth has now become a unifying call to action.

Lifting my gaze from the departing chinstrap penguins, I make a pact with myself that this year nothing is going to keep me from participating in the upcoming Half-Earth Day in October 2018, where innovative and forward-thinking people will share a common path to a sustainable future.

Mapping Earth’s Species to Identify Conservation Priorities

The Half-Earth Project is ‘unlocking a new era in data-driven conservation.’

The Half-Earth Project has launched online the first phase of their cutting-edge global biodiversity map. This unique, interactive asset uses the latest science and technology to map thousands of species around the world and illuminate where future conservation efforts should be located to best care for our planet and ourselves. 

“The extinction of species by human activity continues to accelerate, fast enough to eliminate more than half of all species by the end of this century,” said E.O. Wilson in the New York Times Sunday Review on March 3. “We have to enlarge the area of Earth devoted to the natural world enough to save the variety of life within it. The formula widely agreed upon by conservation scientists is to keep half the land and half the sea of the planet as wild and protected from human intervention or activity as possible.”

Born from Wilson’s book Half-Earth: Our Planet’s Fight for Life, the Half-Earth Project is providing the urgently needed research, leadership and knowledge necessary to conserve half the planet’s surface. The new map sits at the center of this effort.

 By  mapping  the biodiversity of our planet, we can identify the best places to conserve to safeguard the maximum number of species.

By mapping the biodiversity of our planet, we can identify the best places to conserve to safeguard the maximum number of species.

“The Half-Earth Project is mapping the fine distribution of species across the globe to identify the places where we can protect the highest number of species,” Wilson said. “By determining which blocks of land and sea we can string together for maximum effect, we have the opportunity to support the most biodiverse places in the world as well as the people who call these paradises home.”

The Half-Earth Project is targeting completion of the fine-scale species distribution map for most known terrestrial, marine, and freshwater plant and animal species within 5 years.

“This mapping tool is unlocking a new era in data-driven conservation,” said Paula Ehrlich, President and CEO of the E.O. Wilson Biodiversity Foundation and head of the Half-Earth Project. “It will provide the scientific foundation upon which communities, scientists, conservationists and decision-makers can achieve the goal of Half-Earth.”

A $5 million leadership gift from E.O. Wilson Biodiversity Foundation board member Jeff Ubben and his wife Laurie will seed the second phase of the Half-Earth Project’s mapping effort. 

“Half-Earth can’t wait. We have to work quickly and we need to be smart about how we do the work,” said Jeff Ubben. “This map will give us the information we need to make strong conservation investments.” 

“Ed Wilson framed Half-Earth as a moonshot necessary to preserve the future health of our planet,” Ehrlich said. “The investment in our work from Jeff and Laurie Ubben attaches rocket boosters to this moonshot.” 

Join the effort to protect half the Earth for all of life. 

The 8 Million Species We Don’t Know

 Jillian Tamaki

Jillian Tamaki

In this March 4, 2018 New York Times Sunday Review opinion piece, E.O. Wilson explains why species are the fundamental level of study that must be used to identify conservation priorities, and how the Half-Earth Project map is leading the way.

“The 8 Million Species We Don’t Know”
Edward O. Wilson, New York Times Sunday Review, March 4, 2018

The history of conservation is a story of many victories in a losing war. Having served on the boards of global conservation organizations for more than 30 years, I know very well the sweat, tears and even blood shed by those who dedicate their lives to saving species. Their efforts have led to major achievements, but they have been only partly successful.

The extinction of species by human activity continues to accelerate, fast enough to eliminate more than half of all species by the end of this century. Unless humanity is suicidal (which, granted, is a possibility), we will solve the problem of climate change. Yes, the problem is enormous, but we have both the knowledge and the resources to do this and require only the will.

The worldwide extinction of species and natural ecosystems, however, is not reversible. Once species are gone, they’re gone forever. Even if the climate is stabilized, the extinction of species will remove Earth’s foundational, billion-year-old environmental support system. A growing number of researchers, myself included, believe that the only way to reverse the extinction crisis is through a conservation moonshot: We have to enlarge the area of Earth devoted to the natural world enough to save the variety of life within it.

The formula widely agreed upon by conservation scientists is to keep half the land and half the sea of the planet as wild and protected from human intervention or activity as possible. This conservation goal did not come out of the blue. Its conception, called the Half-Earth Project, is an initiative led by a group of biodiversity and conservation experts (I serve as one of the project’s lead scientists). It builds on the theory of island biogeography, which I developed with the mathematician Robert MacArthur in the 1960s.

Island biogeography takes into account the size of an island and its distance from the nearest island or mainland ecosystem to predict the number of species living there; the more isolated an ecosystem, the fewer species it supports. After much experimentation and a growing understanding of how this theory works, it is being applied to the planning of conservation areas.

So how do we know which places require protection under the definition of Half-Earth? In general, three overlapping criteria have been suggested by scientists. They are, first, areas judged best in number and rareness of species by experienced field biologists; second, “hot spots,” localities known to support a large number of species of a specific favored group such as birds and trees; and third, broad-brush areas delineated by geography and vegetation, called ecoregions.

A Long Way to Go to ‘Half-Earth’

All three approaches are valuable, but applying them in too much haste can lead to fatal error. They need an important underlying component to work — a more thorough record of all of Earth’s existing species. Making decisions about land protection without this fundamental knowledge would lead to irreversible mistakes.

The most striking fact about the living environment may be how little we know about it. Even the number of living species can be only roughly calculated. A widely accepted estimate by scientists puts the number at about 10 million. In contrast, those formally described, classified and given two-part Latinized names (Homo sapiens for humans, for example) number slightly more than two million. With only about 20 percent of its species known and 80 percent undiscovered, it is fair to call Earth a little-known planet.

Paleontologists estimate that before the global spread of humankind the average rate of species extinction was one species per million in each one- to 10-million-year interval. Human activity has driven up the average global rate of extinction to 100 to 1,000 times that baseline rate. What ensues is a tragedy upon a tragedy: Most species still alive will disappear without ever having been recorded. To minimize this catastrophe, we must focus on which areas on land and in the sea collectively harbor the most species.

Building on new technologies, and on the insight and expertise of organizations and individuals who have dedicated their lives the environment, the Half-Earth Project is mapping the fine distribution of species across the globe to identify the places where we can protect the highest number of species. By determining which blocks of land and sea we can string together for maximum effect, we have the opportunity to support the most biodiverse places in the world as well as the people who call these paradises home. With the biodiversity of our planet mapped carefully and soon, the bulk of Earth’s species, including humans, can be saved.

By necessity, global conservation areas will be chosen for what species they contain, but in a way that will be supported, and not just tolerated, by the people living within and around them. Property rights should not be abrogated. The cultures and economies of indigenous peoples, who are de facto the original conservationists, should be protected and supported. Community-based conservation areas and management systems such as the National Natural Landmarks Program, administered by the National Park Service, could serve as a model.

To effectively manage protected habitats, we must also learn more about all the species of our planet and their interactions within ecosystems. By accelerating the effort to discover, describe and conduct natural history studies for every one of the eight million species estimated to exist but still unknown to science, we can continue to add to and refine the Half-Earth Project map, providing effective guidance for conservation to achieve our goal.

Much Left to Protect

The best-explored groups of organisms are the vertebrates (mammals, birds, reptiles, amphibians, fishes), along with plants, especially trees and shrubs. Being conspicuous, they are what we familiarly call “wildlife.” A great majority of other species, however, are by far also the most abundant. I like to call them “the little things that run the world.” They teem everywhere, in great number and variety in and on all plants, throughout the soil at our feet and in the air around us. They are the protists, fungi, insects, crustaceans, spiders, pauropods, centipedes, mites, nematodes and legions of others whose scientific names are seldom heard by the bulk of humanity. In the sea and along its shores swarm organisms of the other living world — marine diatoms, crustaceans, ascidians, sea hares, priapulids, coral, loriciferans and on through the still mostly unfilled encyclopedia of life.

Do not call these organisms “bugs” or “critters.” They too are wildlife. Let us learn their correct names and care about their safety. Their existence makes possible our own. We are wholly dependent on them.

With new information technology and rapid genome mapping now available to us, the discovery of Earth’s species can now be sped up exponentially. We can use satellite imagery, species distribution analysis and other novel tools to create a new understanding of what we must do to care for our planet. But there is another crucial aspect to this effort: It must be supported by more “boots on the ground,” a renaissance of species discovery and taxonomy led by field biologists.

Within one to three decades, candidate conservation areas can be selected with confidence by construction of biodiversity inventories that list all of the species within a given area. The expansion of this scientific activity will enable global conservation while adding immense amounts of knowledge in biology not achievable by any other means. By understanding our planet, we have the opportunity to save it.

As we focus on climate change, we must also act decisively to protect the living world while we still have time. It would be humanity’s ultimate achievement.

Solving Wicked Problems

We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone.
— John F. Kennedy

We have a new moonshot today: to manage half of the surface of the Earth to safeguard the bulk of biodiversity. Just as President Kennedy laid the first moonshot at the feet of the graduating students of Rice University, E.O. Wilson has called on our young generation of scientists from around the world to achieve the grand goal of Half-Earth.

The Half-Earth Project is bringing momentum to E.O. Wilson’s vision of Half-Earth, but we will face challenges ahead. One of the most significant challenges will be how to balance the growing human demand for resources with requirements to maintain a healthy ecosystem. The issues are big: establishing sustainable development practices in emerging economies; mitigating human-wildlife conflict; building public support for environmental protection; and many others. Each challenge will require unique and innovative solutions, and that is what the Duke University BluePrint Conference asked students to create.

Earlier this month, I participated as a mentor in the BluePrint “hack-a-thon.” For 24-hours, students and mentors from a variety of backgrounds competed in teams to develop solutions to environmental problems. The goal was for each team to create new approaches to old problems, turning the issue over and over through the lenses of engineering, business, computer science, and other disciplines.

“The ideation competition included 97 students from 11 schools creating and presenting 15 blueprints for the sustainable future of our planet!” said Joshua Furth, BluePrint’s organizer. “These students were mentored throughout the weekend by 36 experts from 15 organizations, while the support of our 21 institutional sponsors underscores belief in Blueprint’s mission and ensured the success of the event.”

At the start of the conference, the organizer, Duke Conservation Tech, introduced the theme “Nature + Progress: focusing on reconciling the natural world with the inevitability of human progress.” After inspirational keynotes from organizations like Conservation X Labs, National Geographic and the World Resources Institute, the teams were off to brainstorm and problem-solve.

Through mentoring 5 teams, I learned as much from the students as they learned from me. Tag-teaming with other mentors, we shared our experiences and insights with the students as they honed their designs. The enthusiasm was catching, and I found myself longing to stay with each team a few minutes more to flush out ideas.

After just 24 hours, their innovations were astounding: new wildlife monitoring systems to reduce animal-transportation collisions; apps to involve the public in scientific data collection; new architecture plans for building complexes that create electrical energy from compost; and business models that reduced space needed for agriculture in addition to reducing methane output of livestock. The list goes on. Each innovation tackled an essential dilemma and spoke to the challenges we’ll need to address to reach Half-Earth.

“Blueprint is about solving wicked problems,” Joshua said. “We are excited to see many of the blueprints from this year’s event continue to prototyping. While the top teams received grants to continue working on their projects, we were surprised and thrilled to see that many more of the teams are eager to work on making their projects a reality.”

The Half-Earth Project is eager to see these ideas come to life. We’re inspired by the ingenuity we saw this weekend and the potential that collaboration across sectors brought to solving environmental challenges. With just 150 students, 30 mentors, and 24 hours, new doors were opened for the future of our planet.

Kellie Laity, E.O. Wilson Biodiversity Foundation’s Communications and Development Coordinator, has worked on a variety of wildlife management projects, ranging from human-wildlife conflict to behavioral research. She endeavors to inspire conservation action through education, storytelling, and hands-on involvement.

The Half-Earth Project has science at its core and our transcendent moral obligation to the rest of life at its heart. In collaboration with our partners, we are working to power one of the grandest conservation efforts of our time, and provide the urgently needed research, leadership and knowledge necessary to conserve half the planet for all of life.

Human Benefits of Protected Areas

“Research from around the globe suggests that parks can successfully balance conservation and development and are one of the most important mechanisms for permanent protection of natural resources,” said Katharine Sims, an economics and environmental professor at Amherst College. Her comments appeared in a recent article titled “Chile Establishes 10 Million Acres of National Parks in ‘Gigantic’ Move for Conservation,” which appeared in the Huffington Post.

The article goes on to say that not only can protected areas be good for national economies, they can also boost local economies and mitigate poverty – if managed well.

Each acre conserved provides valuable natural resources and community development opportunities, the article states. Communities surrounding national parks typically benefit from economic perks of tourism, increased infrastructure, and ecosystem services when compared to similar communities further away.


The benefits of protected areas planned and developed in this way can be seen around the globe. From Thailand to Costa Rica, and from the Czech Republic to Chile where Half-Earth Project partner Tompkins Conservation is doing incredible work, nations that have invested in their natural biological heritage have been rewarded with many tangible economic gains.

Half-Earth Project partner Gorongosa Restoration Project in Mozambique is a living example of the multitude of benefits provided by well planned and managed protected areas. Sustainable development—the principle of meeting human needs while also ensuring the sustainability of the environment for future generations—sits at the heart of Gorongosa National Park’s mission. The park is a 21st century model for protected areas, showing how protecting biodiversity inside the park can economically benefit the surrounding communities with increased employment, education, and healthcare.

The Half-Earth Project has science at its core and our transcendent moral obligation to the rest of life at its heart. In collaboration with our partners like the Gorongosa Restoration Project and Tompkins Conservation, we are working to power one of the grandest conservation efforts of our time, and provide the urgently needed research, leadership and knowledge necessary to conserve half the planet for all of life.

Species at the Core

I will argue that every scrap of biological diversity is priceless, to be learned and cherished, and never to be surrendered without a struggle.
— E.O. Wilson

This week, our Half-Earth Project partner Tompkins Conservation completed the last of their historic 10 million acre national park expansion in Chile, creating Pumalín National Park and Patagonia National Park Chile. These parks will protect countless huemuls, guanacos, condors and other species, establishing a major contribution to the goal of Half-Earth.

Tompkins Conservation’s phenomenal achievement joins other conservation successes over the past year, including the protection of 2 million acres of rainforest in Yagua National Park in Peru, the creation of the largest marine protected area in North America at Revillagigedo Islands Marine Protected Area in Mexico, and the establishment of wetland Lufira Basin Protected Area in the Democratic Republic of the Congo, an area that is roughly the size of Switzerland.


The expansiveness of these areas gets headlines, but conservation areas derive their true greatness from the biodiversity they contain and the species that call these places home. By conserving habitat we protect the delicate interaction of species that are fundamental to ecosystem stability and strengthen the resilience of our planet.

“Each species is a wonder to behold, a long, brilliant history in itself to read, a champion emerged in our time after a long struggle of thousands or millions of years, best of the best, an expert specialist in the niche of the natural environment in which it lives,” says E.O. Wilson.

Yagua is the size of Yellowstone, yet contains 10 times the biodiversity, including birds, monkeys, and fish. Revillegigedo is a “super highway” for rays, sharks, whale sharks, and humpback whales, and supports a coral reef ecosystem with 36 species of endemic fish. Lufira supports numerous endemic species of fish, amphibians and reptiles, and is important to much of Africa’s water supply.

“Species aren’t just names, or points on an evolutionary tree, or abstract sequences of DNA,” Wilson says. “They encode countless millennia of complex interactions between plant and animal, soil and air.” 

Around the world, the places that have magnificent species diversity are threatened by human pressures. These places are losing their sharks and rays, their endemic fish, their amphibians and reptiles, and more. As those species disappear, ecosystems decline, and the health of our planet as a whole is impacted. Each species lost threatens the collapse of the whole.

That’s why getting to Half-Earth starts with protecting the lands and seas that contain the most biodiversity. The Half-Earth Project is mapping the fine distribution of species around the world to identify the places where we have the opportunity to protect the highest number of species. Protecting identified species-rich areas will safeguard the bulk of biodiversity, and ensure the long-term health of our planet.

A Change of Perspective

The impact of climate change — the scars that it’s leaving on our planet — is visible from above, too.
— Captain Mark Kelly

We can learn a lot about Earth from an astronaut’s perspective. Captain Mark Kelly has gone to space many times, and he’s looked at Earth first-hand in a way few of us have. What does he see? The rapid changes humans are imposing on the planet in just the short timespan of his career, leaving huge marks all over the world that are visible from space.

“When I first looked down upon the Amazon rainforest in 2001, I saw vast areas of jungle and a wide and winding copper colored river that went on and on and on. A river that was impossible to miss and like no other on the planet,” Kelly wrote in an article for CNN on January 10, 2018. “By 2011, however, the part that was most noticeable wasn’t the river or the jungle but the large swaths of empty land.”

Kelly notes that the destruction he sees from space indicates a parallel story of devastation on the ground to the species and ecosystems in those areas.

“We see the loss of an incredibly diverse ecosystem that once held endless possibilities for new medicines and other discoveries,” Kelly writes. “We see the loss of a home for so many species that will now have to learn to adapt and survive somewhere else — or not.”

Whether viewed from outer space or through a microscope, the loss of great swaths of forests and individual species are significant to the entire planet. Even if a landscape or seascape can be restored, some species will be gone forever. “Look closely at nature,” E.O. Wilson says in his book Half-Earth: Our Planet’s Fight for Life. “Every species is a masterpiece, exquisitely adapted to the particular environment in which it has survived. Who are we to destroy or even diminish biodiversity?”

The Half-Earth Project, in collaboration with our partners, is working to save half the Earth for all of life, including ourselves.

“As an astronaut,” Kelly writes, “I’m often asked about the climate, our environment, and how we are destroying the Earth. My response often surprises people. ‘Don’t worry about the planet, the Earth will be just fine,’ I tell them. ‘What you need to worry about is us — all of us.’ ”

Wilson says it this way: “It is reckless to suppose that biodiversity can be diminished indefinitely without threatening humanity itself.”

As we expand deeply our scientific understanding and respond to our moral obligation to all living things, the work to protect global biodiversity and secure a healthy planet for future generations continues to gain momentum. From astronauts to field scientists to people everywhere, we all have a role in reaching Half-Earth.
