By approaching this from a regional lens, the Central Puget Sound partners were able to leverage resources to ensure that jurisdictions – regardless of their individual capacity – were able to access high-quality data and tools to understand their existing tree canopy and opportunities to invest in future tree canopy through a lens of ecosystem benefits, social equity and climate adaptation. In addition, a regional analysis provided an overall understanding of regional tree canopy distribution. After all, trees and forests do not care about city lines.
The Urban Tree Canopy Assessment Toolkit details the results of this effort and highlights a model that can be adapted and applied by other regions in Washington State and across the United States.
The Conservancy, Davey Tree, American Forests and City Forest Credits conducted an urban tree canopy assessment and incorporated into multiple tools, including: a planting prioritization based on ecosystem benefits, i-Tree Landscape and Tree Equity Score. To supplement these tools, the Northern Institute of Applied Climate Sciences produced a climate-adaptive tree species guide for the Puget Sound. To encourage and support community action, the City Forest Credits demonstrated how carbon financing can support urban forestry goals.
The products of this partnership can be used by urban forestry practitioners to target investments in urban tree planting and maintenance based on a variety of priorities, including looking at available planting space, equitable distribution of trees, stormwater benefits, and more. These tools can be used to communicate with decision makers using ecosystem service benefit and more.
Since these tools cross jurisdictional boundaries, the final products offer the opportunity for those in different jurisdictions to connect, learn from each other and even potentially collaborate on future analysis and projects.
Those looking to develop their own regional effort to understand urban canopy can look to this toolkit for Seven Steps to Building an Urban Tree Canopy Model. Core to this is connecting with partners with different types of expertise and connections.
