Leafsnap


Help scientists study tree species distribution.
Identify and locate tree species using an iPhone or iPad.

Leafsnap is an exciting new mobile app that is designed to help citizen scientists identify and locate tree species from photographs and ultimately help the scientific world develop a better understanding of biodiversity. Developed by Columbia University, the University of Maryland, and the Smithsonian Institution, Leafsnap contains a unique visual recognition software that helps users identify species from the photographs taken straight from your iphone or ipad.

The app is completely free and will be the first in a series of apps that takes advantage of the newly developed recognition software. The app also contains high-resolution photos of the leaves, flowers, fruit, seeds, and bark of all sorts of species, and is a wonderful visual field guide. Currently, the species of New York City and Washington D.C. are supported, but this list will be expanded in the future.

The app is very user friendly and easy to use. With each photo of a leaf you take, the photo, species information, and geo-location is all automatically sent to the Leafsnap database for scientists to study species distribution.

This Leafsnap website shows the tree species included so far, a visual map of the collectors that have recently contributed, and more information on the project. Contributing to citizen science couldn’t be easier than with this visually engaging app! Get snapping and identify a tree near you!
