Geographic Resources

Reliable data is the foundation for an effective urban forest program. We use the latest mapping and web technology to maintain current information on the District’s trees and then to share this information with the public.

Tree Inventory

Before you can restore your neighborhood's tree canopy you need to know what there is to restore. Casey Trees' completed inventories include Dupont Circle Street Trees, Newly Planted Tree Mortality, and street trees for the entire District. We can help your neighborhood or organization take stock of its trees. This is the first step towards longer term management plans. Learn more
