Plant leaf image collection through the iNaturalist app.

Biotracker NSF Project

We are collecting images of individual plant leaves that will be used to help create the world's most comprehensives electronic field guide for plants. Our existing iPhone app, Leafsnap, uses visual recognition to help identify tree species from photographs of their leaves. However, our current database only includes trees in the Northeast U.S. Help us expand that coverage by uploading images of tree leaves using the iNaturalist app (available for both iOS and Android devices). Detailed instructions for participating in this exciting mobile crowdsourcing project are available here:
