Emerald Ash Borer: A Green Menace
Where is EAB in Colorado?
- EAB has been confirmed in unincorporated Larimer County and in the cities of Boulder, Gunbarrel, Longmont, Lafayette, Lyons, Superior, Broomfield, Westminster, Erie, Arvada and Thornton.
- The entire City of Boulder was presumed infested at the close of 2015.
- In 2019, EAB was confirmed in the City of Broomfield, the first confirmation in Colorado outside of a federal quarantine, and (for the first time) in unincorporated Larimer County. The EAB quarantine around Boulder County was repealed effective Dec. 30, 2019.
- The most recent confirmed detections have been in Erie (June 2021) and Thornton (June 2022).
The Colorado State Forest Service is leading this project to prepare small and mid-sized communities along the Front Range for the emerald ash borer.
