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, fruit, petiole, seeds, and bark. Leafsnap currently includes the trees of the Northeast and will soon grow to include the trees of the entire continental United States.

What's New in Version 1.05

- Fixed a major bug that crashes the app when using the Snap It! feature

Leafsnap deserves all our appreciation. What a joyful "delivery system." If you care at all about learning and our miraculous, verdant planet, you will revel in this software. Thank you so much.
