Count of Leesburg Ash Trees Is Underway

Leesburg's Tree Commission and the Loudoun County Master Gardener Tree Stewards are partnering to tally ash trees in Leesburg.
The estimate of the number of trees will help the commission assess the potential impact of the emerald ash borer, an invasive pest that kills the trees.
With the borer's spread, most of the ash trees in Leesburg could potentially be lost. By tallying the trees, the commission can estimate their contribution to the tree canopy cover and the potential loss in canopy.
The Tree Stewards will survey ash trees visible from public streets. They will not enter private property. The effort kicked off Aug. 6 and will probably be completed by early fall, before the leaves fall.
