Students in the horticultural program have been using the digital field guide Leafsnap, complete with visual recognition software, to help identify leaves, flowers, and trees on school grounds and the nature reserve that surrounds the school campus. Students become producers of digital content by adding to the biodiversity database that is part of this free mobile app developed by researchers at Columbia University, University of Maryland, and the Smithsonian. Students will demonstrate how to use Leafsnap and share pictures from their walks.
