Emerald Ash Borer in Colorado

Emerald ash borer (EAB) was first detected in Colorado in Boulder and continues to expand. Thanks to the Colorado Tree Coalition (CTC) and the EAB Response Team, Colorado communities are informed about the potential impacts and management actions needed to prepare for likely future infestations in urban ash tree populations.

Through the Landscape Scale Restoration (LSR) Grant Project, the Colorado State Forest Service (CSFS) is working to build on this foundation and increase resources for small and mid-sized communities along the Front Range.

Your Ash is on the Line is a project that includes:

  • Inventories of public ash trees in small communities (less than 20,000 people) along the Front Range
  • Expansion of the EAB Response Team (a group of municipalities and industry professionals) to share ideas and solutions
  • Wood utilization workshops
  • Online EAB toolkit
  • Front Range EAB Management Plan
