Leafsnap is the first in a series of electronic field guides being developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution. This free mobile app uses visual recognition software to help identify tree species from photographs of their leaves.

Leafsnap contains beautiful high-resolution images of leaves, flowers, fruits, petioles, seeds, and bark to aid identification. These high-resolution images were created by the conservation organization Finding Species.

Leafsnap currently includes trees found in the Northeastern United States and Canada. The inclusion of Canadian trees is through collaboration with the Canadian Wildlife Federation, with support from TD Friends of the Environment Foundation.

What's New in Version 1.07

- Expanded species coverage to Eastern Canada, with 36 new species
- Fixed minor bugs

Upload error in latest version

After updating the app I get upload errors after I take a picture.

Help me please 😔

The snap it part is taking a really long time, I waited 20 mins for one leaf and it still continued to load either than that it's a good app

Doesn't work

A clever idea, but I tried it on several common leaves and it couldn't figure them out. Couldn't get it to successfully identify on all my attempts. Even with a white sheet of paper behind the leaf, it says it needs white paper sometimes. Has potential, but is just in experimental phase for now.
