Emerald Ash Borer in Colorado

Following detection of the Emerald Ash Borer (EAB) in Colorado, the Colorado State Forest Service (CSFS) and many partners mobilized to document and slow the insect’s spread, understand the damage it was causing, and keep communities informed about their options for preparing and responding to likely future infestations.

The Your Ash is on the Line project was funded by the USDA Forest Service through a Landscape Scale Restoration grant to create and share EAB management resources for small and mid-sized communities along the Front Range. Active from 2018-2022, the project included:

  • Inventories of public ash trees in small communities (less than 20,000 people) along the Front Range.
  • Support to and collaboration with the EAB Response Team and Emerging Pests in Colorado Committee (EPIC) of the Colorado Tree Coalition.
  • Urban wood utilization workshops, which laid a strong foundation for a new Colorado Chapter of the national Urban Wood Network now in development.
  • Online Management Resources for Communities, which provide easy access to the best available information and tools on EAB detection, planning, and response.
  • An EAB Management Plan Builder, which communities can use along with their project inventory data to craft actions and seek support for management.
