Forest Health Management
We provide site-specific forest management advice to private forest landowners, municipalities, and local government land managers. Aerial reconnaissance and ground surveys play a pivotal role by identifying agents-of-change as well as their effects on forest cover types.

Mountain pine beetle and Spruce beetle are two of the most important insect pests in Wyoming's forests. Since the early 1990s, these native beetles have caused tree mortality over millions of acres of federal, state, and private forests in Wyoming. Currently, western spruce budworm is Wyoming's most concerning forest health issue.
Emerald ash borer (EAB) is a non-native invasive insect that infests native North American ash trees. It was accidentally introduced to the Midwest and has since been spreading to other areas of the U.S. and Canada.
Satellite infestations of EAB include Boulder County, Colorado. Ash trees are native to parts of eastern Wyoming, but considering the widespread urban planting of ash trees, EAB has the potential to impact most Wyoming communities eventually. By not transporting firewood, we can substantially delay EAB's arrival in Wyoming. EAB has not yet been detected in Wyoming and there is a state EAB response plan in place.
Wyoming's biggest forest health threats include:
Lack of forest age class diversity
Too much dead wood
Altered fire return intervals
Four biggest fire seasons within last decade
Wildland-urban interface development
Four decades of decline
Economically difficult to remove wood
Lack of water
Low moisture & high temperature
Fire suppression & less harvesting = more trees
More trees = more water needed
Early 2000s drought led to more tree mortality
Competition alone is enough to lead to beetle attack
When combined with drought and disease, these factors can cause substantial tree mortality
