Emerald Ash Borer

The species of ash trees on the Front Range have little resistance to Emerald Ash Borer. Larvae burrow under the bark and sapwood, creating S-shaped mounds under the bark and blocking nutrient flow which ultimately kills the tree. EAB has killed many millions of ash trees in the US since first being discovered in the early 1990s. Protect your ash trees with regular maintenance by Donovan Arborists.
