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.

2012-05-05First app that has compelled me to write a review. Simply elegant. Sure it needs to grow and the description states that. The interface and aesthetics are beautiful. Wow, and free? I would buy this app any time. PLEASE continue to expand and grow this app (more geographic regions
2012-04-24Excellent app--wish I had this when I took field botany/taxonomy. The database is chock full of high quality images that offers images of bark, twigs , flowers, and fruit along with leaves. It appears that expansion of this app is still occurring. It could use some range maps
2012-04-17I have tried this app with much success. I think you need to keep in mind how amazing it is that the program is identifying a plant by shape. If you know you will be using the app bring a white piece of paper or large index card. Definitely beats paging through a limited book or
2012-04-15The games are brilliant. What potential for growth. You should seek more funding for this. A larger database and the ability to allow database loading from smartphone is what you would need greatly expand it. I would offer a short class to columbia and cornell plant phys students
2012-04-14More updates will help a lot. Little tricky in the field, if prepared it is a wonderfully tool.
2012-04-02Love the app however would be better if you add pix of the entire tree. Good work.
2012-03-09Looks great. Many of the trees from this region extend into Minnesota.However, the description says "updates coming shortly". It has been almost a year without an update.
