San Francisco’s city government, along with California Department of Forestry and Fire Protection (Cal Fire) and Friends of the Urban Forest, recently launched the Urban Forest Map, an open-source web-based tool that not only catalogues the city’s trees, but puts an economic value on the range of ecosystem services they provide the city.

Amber Bieg, manager of the project, said Urban Forest Map is like ”a census for trees.” Just like human populations are estimated through personal data submitted by residents, this tool will also rely on data and images uploaded from around the city. Fast Company explains: “The reasoning behind the ambitious project is simple: San Francisco has only 90,000 trees in its database, but there are hundred of thousands in the city. It costs city governments $3 to catalog a single tree. So instead of wasting city cash on the issue, the UFM intends to harness the power of community for a comprehensive database.”
