The Huffington Post reports on a new iphone app: "Compiled from the city tree census, this free app identifies your iPhone's location and displays all the surrounding trees on a map. Opening the app here at HuffPost reveals that within a five block radius of the SoHo office, there are 407 trees, creating approximately $83,000 in benefits to the city each year. The 36 species of trees reduce CO2 emissions by 120,380 lbs and prevent 446,256 gallons of storm water run off every year"
Sounds like a great tool for an urban biodiversity campaign...
