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 :)

Nice learning app

Once I got over the fact that this app wasn't perfect and that the photo tool never really worked, I realized the utility of it. Taking walks around the neighborhood and parks, Leafsnap helped to familiarize me with my local trees. It would be nice to be able to "collect" the data for tees you've identified in a list, or otherwise flag then somehow. And if the image match for the photos got better, that would be wonderful. But for now, I'm perfectly happy that I'm much more knowledgeable about trees than I was just 6 months ago.

Love the concept; wish it worked

First of all, thank you for this app. I LOVE this concept, but the app has just never worked for me. Starting with just trying to take the photo, it almost always has a problem with my background not being white enough. If I can get past that, it usually doesn't upload and I get an error message. If I can get past that, it usually doesn't see the leaf shape properly and provides me with matches that are nothing like the leaf I submitted. I imagine part of my problem is that I'm in San Diego and probably our native species aren't in the database yet. I'm going to wait for the developers to make their way out to the west coast, but I'll keep checking in.
