Columbia University, the University of Maryland, and the Smithsonian Institution are working on visual recognition software to help identify species from photographs. Leafsnap is the first in a series of electronic field guides being developed to demonstrate this new technology.

This free mobile app helps identify tree species from photographs of their leaves. Leafsnap currently includes the trees of the Northeast and will soon grow to cover the trees of the entire continental United States.

The realization of Leafsnap was possible thanks to the collaboration between Peter Belhumeur (Columbia University), David Jacobs (University of Maryland), and John Kress (Smithsonian Institution).

The high quality photographs on the website leafsnap.com and in the app were made by the the not-for-profit nature photography group Finding Species.

On November 9, the European Council approved the Nature Restoration Law, a regulation for the restoration of ecosystems.

The risk is that the objectives lose their concreteness in implementation.

On November 9, the European Council, the body defining the EU's policy directions, approved the Nature Restoration Law, one of the four main pillars of the European biodiversity strategy for 2030. A great achievement, yet leaving a bit of bitterness, considering the approved regulation was significantly weakened compared to the original.
