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.

Firewood is widely recognized as a major source of non-native forest insect and disease infestations. A rule governing the importation of untreated firewood into Vermont went into effect on May 1, 2016. Visitors to Vermont State Parks, Vermont State Forests, and the Green Mountain National Forest may only bring firewood originating from Vermont or that is heat treated and in its original, labeled package. To help slow the spread of emerald ash borer within Vermont, ash firewood that has not been heat treated should not be moved outside of the Emerald Ash Borer Infested Area in Vermont.
