Urban Forest Map

Main Project Information
Where California United States

The Urban Forest Map is a collaborative effort to map every tree in the city of San Francisco. As a citizen forester, you can get involved by searching for trees, verifying records, and by adding the trees in your neighborhood!

Along the way, researchers will use this data to calculate the environmental benefits that the trees are providing -- how many gallons of storm water they are helping to filter, how many pounds of air pollutants they are capturing, how many kilowatt-hours of energy they are conserving, and how many tons of carbon dioxide they are removing from the atmosphere. The information we gather 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.

The goal of Urban Forest Map is to provide a one-stop repository for tree data, welcoming information from any agency or group and enabling and celebrating citizen participation. Together, we'll work toward building a complete, dynamic picture of the urban forest.

How to Join

To contribute, sign up for an account ( and then follow these simple steps:

1. Find a tree: Search for the trees near you. Find trees that bear edible fruits and nuts or those with beautiful flowers. Search for the biggest trees in your neighborhood -- then go visit them.

2. Add a tree: The Urban Forest Map grows as citizen foresters like you add trees. Show a tree's location by putting a dot on the map, then provide as much information as you can.

3. Edit a tree: Check out the facts about the trees around you and update when you can. Don't forget to add alerts! With your help, we'll track changes in the urban forest and watch it grow
