Description

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.

Disappointing at Best

Even knowing the vagaries of WiFi connectivity in the field and the proliferation of invasive & non-native species in suburbia, this app has repeatedly failed to be of any real use.
My “collection” of two unidentifiable leaves remains a total mystery to the app, which keeps making suggestions of VERY different-looking leaves. (It once told me a pin oak was a maple, so I’m not too surprised.) The constant inability to access the servers when outdoors led to my photographing some very wilted leaves in an attempt to get them back indoors with a reliable WiFi connection — but lately even that has been failing with repeated, “RECOGNITION ERROR - Failed to poll server” errors even with a good WiFi connection that other apps are having no problems using.
The only reason this app is still on my iPhone is that I can (sometimes) scroll through pictures in an attempt to manually ID a tree... which often leads to better results than the “Snap It!” function. Definitely needs a LOT of work, or at least a change in advertising & name so people know they cannot depend on what is supposed to be the app’s primary feature and function.
Would give it 1 star if the pictures in the database (assuming I can access them) weren’t clear... but in reality I give it 1½ stars at best in its current form.

Crashes a lot

Crashes a lot. Then when you reopen the app pictures are missing from your collection. When trying to identify a tree, it will give you several options. If the options are similar (5 different kinds of maple) then at least you can say well, it’s some kind of maple. But sometimes the 4-5 trees are wildly different trees, they just happen to have the same leaf shape. Then you have to use your own knowledge to figure it out. (A magnolia tree is very distinct, but apparently its leaves look like a lot of other trees).

So this app has some usefulness, but it isn’t going to magically identify a plant for you. It just helps narrow it down so you can do the rest of your research. More convenient than having a book that you have to flip through, so there is that.
