Just heard about this project---sounds like an excellent idea. http://www.kickstarter.com/projects/winterroot/wildflowers-of-detroit There will be a BIG need for expert ID and editing of submissions...and I'm thinking about invasive/noxious plants that will be inevitably be photographed, such as Amur honeysuckle and poison ivy. This app could be used as a way to pinpont areas of infestation. BUT I believe that this effort uses technology in a laudable way. Anything that gets folks paying attention to the wild plants all around them, raises awareness of the natural world, is GOOD! Ironic that the ubiquitous phone, which serves to distract so many folks, may be used to direct attention to nature!
