    Particulate Matter Concentration

    This map displays the location of particulate matter pollution within San Francisco such as areas with a high intensity of vehicle traffic. Trees in these areas can help improve air qual- ity by intercepting airborne particles.

    Air Pollution

    Air pollution sources in San Francisco are largely tied to the vehicle network. Trees can help improve air quality in affected areas by absorbing gaseous pollutants (car- bon dioxide, sulphur dioxide, and nitrous oxide) and by capturing airborne particulate matter on leaf surfaces.

    Open Spaces & Natural Areas

    Public open space refers to lands that are publicly owned, publicly used, and publicly accessible. The Recreation & Parks Department has identified 32 “Natural Areas” that contain remnants of San Francisco’s historic landscape and natural heritage and support an array of native habitats and species.

    Urban Bird Refuge

    The Planning Department’s Standards for Bird-Safe Buildings identify areas of the city where the presence of birds may require certain building treatments to ensure bird safety. These refuge areas also point to areas where trees can sup- port wildlife such as birds.

    Locations of Severe and Fatal Traffic Injuries: Pedestrians, Cyclists, & Drivers

    Street trees can act as buffers between vehicle traffic and pedestrians and bicyclists. Street trees can also be employed as a traffic calming strategy to improve safety and slow vehicles.

    The Pedestrian Framework of San Francisco displays key walking streets within the city that could be prioritized for increased street tree planting or restocking of empty tree basins.

    Many Opportunities to Participate
    San Francisco’s urban forest is a vital piece of city infrastructure. It provides enormous benefits and supports the ecological function of the city. It requires a long-term plan to ensure its ongoing health and sustainability. The Urban Forest Plan provides a phased approach to planning for trees and vegetation in the city’s landscape. The three phases outlined here will together form a comprehensive strategy for San Francisco’s urban forest.

    Phase 1

    Phase 1: Street Trees was developed by the Planning Department in collaboration with the Department of Public Works , Urban Forestry Council and, Friends of the Urban Forest. Content for the Plan was informed by a series of meetings, workshops, public forums and think tanks with urban forestry specialists from 2012-13. In addition, the Plan is informed by two related efforts including a Street Tree Census and Street Tree Financing Study.

    Phase 2

    To Come: A subsequent planning effort is needed to create a specific vision and strategy for trees in parks and open spaces. Such a plan, developed in coordination with the Recreation & Park Department, would address policy, managment and financing needs of park trees. Grants and other funding sources should be secured to create the Plan.

    Phase 3

    To Come: The third phase of the Urban Forest Plan will develop recommendations for trees on private property and greening opportunities on buildings. Support for property owners in maintaining and planting trees as well as guidelines for green roofs, walls and other greening tools should be included.
