About this site

This web site displays the Urban Tree Canopy (UTC) assessments completed by the USDA Forest Service’s UTC assessment team and other organizations. The University of Vermont Spatial Analysis Laboratory (SAL) maintains this site. If you have questions or comments please contact Jarlath O'Neil-Dunne, Director of the SAL. No endorsement by the USDA is expressed or implied. 

How to use the map

Each community with a UTC assessment is represented by a point (a dot with a tree icon).  Use the map interface to click on the community of interest.  The side bar will provide basic information from the UTC Assessment in addition to links to download the report and land cover data. When zoomed out points that are close in proximity to one another are aggregated into a colored circle with a number reflecting the number of communities that have been aggregated. As you zoom in the aggregated points will separate.  Alternatively, you can click on the aggregated circle to zoom in.

About UTC Assessments

The aim of a UTC assessment is to help decision makers understand their urban forest resources, particularly the amount of tree canopy that currently exists and the amount that could exist. The UTC assessment protocols have been applied to dozens of counties, cities, and towns in the United States and Canada. The information from these assessments has been used to inform UTC goals, prioritize locations for tree planting efforts, establish urban forestry master plans, understand patterns of environmental justice, inform sustainability plans, and justify budget increases for urban forestry programs. For more information please visit the Forest Service’s UTC page.
