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 maintains its own tree registry. One of the largest trees in Loudoun County is pictured above. The Shumard oak is located in Algonkian Regional Park. It is 112 feet high and 176"around the trunk. The tree is estimated to be about 200 years old. More information about the big trees in Loudoun may be found in the Loudoun County Big Tree Registry.
