Applications are now open for the Virginia Department of Forestry (DOF) Emerald Ash Borer Cost-Share Program, which offers financial assistance for protecting ash trees from the invasive emerald ash borer. Since its arrival in the U.S., the emerald ash borer has killed millions of ash trees and caused billions of dollars in damage.
Starting in 2018, the cost-share program, supported through Virginia invasive species funding, has reimbursed the costs for more than 2,400 ash treatments statewide. Landowners and organizations – including municipalities, nonprofits, educational institutions and homeowner associations – can apply for the program until June 13.
All ash species native to North America are susceptible to emerald ash borer and can be destroyed in as little as one year. The best way to save ash trees is treatment with systemic insecticides by a certified applicator, which protects the trees for up to two years, said a DOF spokesperson.
To be considered for cost-share funds, a DOF forester must first assess the trees prior to treatment. The DOF cost-share reimburses up to 70% of the costs for emamectin benzoate treatment by a certified applicator. To be eligible, treatments must be for green, white, black, blue, pumpkin, or Carolina ash trees at least 12 inches in diameter (at chest height) with no more than 30% crown dieback.
The local DOF forester can help identify ash trees, determine whether a tree is suitable for treatment and the cost-share program, or, if the landowner decides removal is the best option, provide information on ISA-certified arborists.
Rockbridge’s area forester currently is Mitchell Kim in the Salem regional office. His email address is [email protected]. gov and his phone number is (540) 682-0242.
“The emerald ash borer arrived in Fairfax in 2008 and is likely now in every Virginia city and county,” said Forest Health Program Coordinator Amanda Conrad. “Ash trees are commonly found in yards and lining roads. Left untreated, these trees will become infected by emerald ash borer and die, posing a significant risk to public safety.”
