Seattle’s urban forest is made up of all the trees on public and private land. Trees are part of the urban forest along with plants that grow in the understory, soil, and waterways next to or beneath the tree canopy.

Seattle communities and our urban forest need each other. Trees improve public health, protect our environment, and provide many other economic and community benefits. Like roads, bridges, and utility lines, our urban forest is part of Seattle’s public infrastructure, and it requires our collective care.

The City of Seattle actively manages the urban forest, relying on multiple City departments, including planning, utilities, transportation, engineering, and parks. Nine departments work together under the Trees for Seattle umbrella and charter structure to support Citywide coordination and alignment. 

OSE plays a central role in Seattle urban forestry, working with staff and leadership across the City and in partnership with communities to develop a shared urban forest management vision and approach. OSE also leads coordination and reporting for citywide urban forestry policy, issues, and initiatives, convenes urban forestry interdepartmental teams, and staffs the Urban Forestry Commission. Together, we can keep Seattle’s trees and urban forest healthy and growing.   

OSE Focus Areas

Foresting Seattle uses a neighborhood-based approach to growing tree canopy in focus neighborhoods, promoting community leadership, green space restoration, and youth employment opportunities. 
 

Seattle is developing a Canopy Equity and Resilience Plan to guide departments to grow more trees in neighborhoods that need them most and in partnership with the communities most affected.

Every five years, the City conducts a tree canopy cover assessment to track trends of our forest coverage. Seattle's canopy goal is to reach 30% canopy cover by 2037, as well as to improve tree health and equitable distribution of trees to support community health and resilience to climate change.  

The City convenes an Urban Forestry Commission to advise the Mayor and Council on urban forestry. This diverse group of community members meets regularly to discuss policies and processes for improving our urban forest for our communities. The commission is regularly recruiting new members; consider joining the conversation!

Seattle's Urban Forest Management Plan provides a framework for policy and action that guides City government decision-making to help Seattle maintain, preserve, enhance, and restore its urban forest.
