Don't Move Firewood

Vermont Agency of Natural Resources. Department of Forestry, Parks, and Recreation.

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.
