Since the 1940s, local governments and forest-related organizations have been searching for, identifying and documenting the biggest trees in the nation.
The Virginia Big Tree Program maintains a registry of the five largest specimens of over 300 native, non-native, and naturalized tree species. The Virginia Big Tree Program is coordinated by the Department of Forest Resources and Environmental Conservation at Virginia Tech.
Loudoun County has 15 of the state's champion or co-champion trees and has more than 41 trees in all listed in the Virginia Big Tree Program. Champion trees are the largest of their species.
Loudoun County’s Big Tree Registry program is currently being updated. We hope to have an updated list in the future. In the meantime, we invite you to apply for the State’s Virginia Big Tree Registry.
Loudoun County has an interactive map that shows the general location of the county's big trees. Please note that this map is currently not being updated as the county is in the process of updating the Big Tree Registry program.
