With the quarantine of ash trees in Arkansas, the threat of the Emerald Ash Borer (EAB) to millions of Oklahoma ash trees intensifies for southeastern Oklahoma, especially McCurtain and Le Flore counties. As the pest is literally next door, Oklahoma Forestry Services is asking Oklahomans to help prevent the infestation spread and be on the lookout and report any signs that the insect is in the state. Please notify Oklahoma Forestry Services at 405-522-6158 if you see signs of EAB infestation in ash trees. For more information about the Emerald Ash Borer visit www.forestry.ok.gov/tree-pest-alerts.
