iPhone Screenshots


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

Version 1.08

Leafsnap now works for iPhone 7. You can also now browse species without being connected to a Wi-fi network.

Not practical

Everything has to be 100% perfect for this app to work. Not good for field reference. No one has a blank piece of white paper with them at all times in the field.

I’m not sure how much more clear I can get with a leaf on a white background and it still says to retake the pic.


Does not work

My Two year old can identify leaves better than this app. I had a perfect red maple leaf on a white background and it could not even upload and identify it. Never worked on any leaves
