Loudoun County is seeking nominations from residents to help identify and document the largest trees in the area for its Big Tree Registry. The initiative aims to raise awareness about the value of trees and promote the urban tree canopy.
“The Big Tree Registry is a great way to help people become more aware of trees. This program promotes the urban tree canopy and demonstrates the value trees add to our community,” said Loudoun County Forester Lindsey Long.
Currently, there are 20 trees in Loudoun County listed in Virginia’s Big Tree Registry, with eight recognized as “champions”—the largest of their species in the state. Among these is a Shumard oak located in Algonkian Regional Park, which stands at 109 feet tall and has a circumference of 184 inches.
Residents can nominate large trees online through the county’s website at loudoun.gov/BigTreeRegistry. The site provides an interactive map displaying locations and details such as species, height, circumference, and crown spread—the latter being the distance across a tree’s canopy.
Additional information about Loudoun County’s existing and potential tree canopy can be found at loudoun.gov/TreeCanopy.
