DeKalb County's Urban Tree Canopy (UTC) assessment is underway!

The purpose of this project is to establish a current tree canopy map, and to use historical data to track tree canopy change over time. The data from this research will provide better understanding of the environmental impacts of land use decisions and will help inform strategic planning for DeKalb’s urban forests.

This UTC study will include all areas of unincorporated DeKalb County, GA--a total of 158 square miles!


**** Engagement Announcements ****


In order to validate the data we are collecting, beginning in late March and early April, we will be conducting site visits to various locations throughout the county to observe the trees. Volunteers will be asked to visit several locations, take photos, and make detailed notes about their observations. Training and detailed instructions will be provided.

Thank you to everyone who signed up as a volunteer!
