Tree Pests

This article explores significant tree pests that threaten our forests, including the Asian Longhorn Beetle, Emerald Ash Borer, Gypsy Moth, and Western Pine Beetle. The Asian Longhorn Beetle, native to China, was introduced to the U.S. through infested materials. The Emerald Ash Borer has devastated millions of trees, prompting firewood quarantines for prevention. The Gypsy Moth, present since 1870, primarily targets oaks and aspens. Lastly, the Western Pine Beetle affects Ponderosa and Coulter pines across western states. Stay informed to protect our vital forests!
