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

Customer Reviews

Great app, couple suggestions!

I love this app. Works fairly well, great information and fun memories games to really lock in the plants. 2 suggestions: if a plant isn't available, it should default to a web browser to look it up or you should be able to name it temporarily yourself. I don't like "untitled" plants sitting in my collection. Second, in the information part of the plant, there should be a section on whether it's edible. I think that would be extremely beneficial in emergency situations. Perhaps you have the app or you remember playing one of the games and that information could be a life saver! Thanks and keep up the great work :)

I love this app!

I've used this app's image recognition feature successfully on a number of leaves. The correct tree is generally in the top three or so choices offered up by the app. The images in the provided catalog are clear and easy to use for manual identification and to narrow down the choices offered by the auto recognition feature. There are a number of other great features as well! Great job folks!

Really Good

I don't know what everyone else is saying, this app works pretty while with only a few issues. First thank you to the company that made this!!! Help me out a lot with a tree ID project for my ag. Science class. The only crappy 2 things about this app is you have to have the leaf on a white peace of paper. Second it gives about 15 unrelated leafs how ever, every time I've used it my leaf was in the list, you just have to look for it.
