Explore Biodiversity with the
Half-Earth Project

Science is the core of the Half-Earth Project. Using the best available species data, our team is mapping species globally to an unprecedented 1km resolution, and using this information to identify conservation priorities where we have the best opportunity to protect the most species.

There are many ways species information is gathered, and citizen science efforts are playing a growing role. Working together with scientists, planners, communities, decision-makers at all levels, we can all help document the natural world, and share and use that information for positive change.

To participate in this effort to gather species information, we invite you to submit your data observations to the Half-Earth Project through the iNaturalist app, the Map of Life app, or the eBird app, as listed below.

Share your species observations with the Half-Earth Project.

iNaturalist: Using the app, join the 91st Birthday Half-Earth Project on iNaturalist, start exploring, and share your observations with the Half-Earth Project under the “Projects” tab.

Map of Life: This app developed by our Half-Earth Project partner allows you to collect and identify species observations around the world. Download the app mol.org/mobile#/ to use for your next exploration.

eBird: This app is designed especially for birders. Use this app to explore birds and hotspots near you and wherever you go. Use #EO91 in your checklist comments to share your observations with the Half-Earth Project. ebird.org/home

However you choose to participate, your data can help us better understand the natural world around us. So the next time you’re out in nature and see an animal or plant or insect or other living species, make an observation, share it, and participate in saving our shared planet.

We also invite you to sign the Half-Earth Pledge.
