Mountain Pine Beetles

Although there are various bark beetles species found in Wyoming, the Mountain pine beetle is the most widely recognized for its impacts. The beetle kills pine trees through larval feeding and by introducing blue stain fungus into the sapwood. In 2011 aerial surveys estimated that over 3.3 million acres of federally managed forests in Wyoming were affected by the Mountain pine beetle. This is why the Wyoming Weed and Pest Council and the Wyoming Department of Agriculture have designated the Mountain pine beetle as a state pest. Working closely with the Wyoming State Forestry District offices, the timber industry and local communities, Weed and Pest Control Districts help on various levels with local programs. The district programs may vary from education, chemical cost-share programs or even the hiring of sawyer crews.
