As much as Arlington values its trees, the County is challenged by its increasing population and the development that this brings. Generally speaking, tree canopy refers to the part of a city that is shaded by trees. Several studies have been performed on our urban tree canopy using satellite imagery to locate the trees in our community.
Our most recent study showed some trends in our tree canopy:
- With a current tree canopy percentage of 41%, Arlington appears to be staying constant with overall tree canopy, compared to 2011 (40%) but has not rebounded from our first measurement in 2008 (43%). Most of the recovery came from parks, which helped offset the losses on residential properties. Find the Current Urban Tree Canopy Analysis here.
- Tree canopy has increased in our parks, with very few parks showing significant reductions in tree canopy, since 2011
- Private residential properties show the greatest opportunity for more trees. Penrose, Aurora Highlands and Bellevue Forest have had the greatest increase since our last measurement. The Rosslyn/Courthouse area, and the northwestern area of Rock Spring, down to Dominion Hills, have shown the greatest decline in trees since our last measurement.
