The Urban Forest Map is an online database and map of San Francisco’s trees. Anyone can look up — or add — information about trees, such as their location, health, species and more. The Urban Forest Map automatically calculates the environmental benefits provided by the trees, by a specific species or even by an individual tree.
This growing database will help urban foresters and city planners to better manage trees in specific areas, track and combat tree pests and diseases, and plan future tree plantings. Climatologists can use it to better understand the effects of urban forests on climates, and students and citizen scientists can use it to learn about the role trees play in the urban ecosystem.
If you have a lemon tree, be sure to add it to the Urban Forest Map so it can be counted in the Just One Tree campaign, which aims to make San Francisco self-sufficient in its lemon needs and serve as a model for how a city can grow more food locally.
