FOR IMMEDIATE RELEASE
Emerald Ash Borer Detected in Fort Collins
State and City experts have confirmed the presence of emerald ash borer (EAB) – an invasive, highly-destructive
pest of ash trees – on the north end of Fort Collins, just outside city limits. This represents the second detection in the
county, and the fourth confirmation of EAB in Colorado outside of Boulder County. Spotted by a local, licensed tree
care company, identification of gathered EAB samples was confirmed this week by entomologists from Colorado
State University.
EAB was first confirmed in Boulder, Colorado in 2013. Since then, the pest has been identified in several other
municipalities in Boulder County including Broomfield (August 2019), Westminster (September 2019), and Berthoud
(October 2019).
Six years ago, a state quarantine was established in an effort to prevent or slow the insect’s spread via the
movement of ash nursery stock, firewood, and other wood that may have been contaminated. In 2019, the Colorado
Department of Agriculture (CDA) repealed the Boulder County quarantine due to the discovery of EAB outside of
Boulder County. Human transport of infested ash wood, such as firewood or other raw material, most likely
contributed to the arrival of EAB in Fort Collins.
Approximately 14 percent of all city-owned trees are ash (Fraxinus spp.), with many additional ash trees located on
private properties throughout Fort Collins. In response to the arrival of EAB, Fort Collins will continue to follow the
City’s Emerald Ash Borer Management and Response Plan, managed by the Forestry Division. Since the City’s
2015/2016 budget cycle, the Forestry Division has received funding to selectively remove and replace ash trees in
poor condition, shadow plant ash trees that are not planned to be treated long term, evaluate all ash trees on public
property and provide EAB education and outreach to the community. As part of the response plan, the City will start a
treatment rotation of strategically selected, healthy public ash trees in Spring of 2021.
EAB attacks and kills both stressed and healthy ash trees, typically within two to four years after infestation. At this
time, the Forestry Division is advising Fort Collins residents to act now and start implementing their own EAB
management plans. Residents should first determine if their property has any ash trees, and if so, evaluate the
condition of each tree, with continued monitoring throughout the year. Residents should also decide whether to have
infected ash trees treated, or removed and replaced. City Forestry staff urge residents to weigh the benefits and
costs associated with ash removal and replacement, versus ongoing insecticide treatments.
“It’s important to remember that this is a natural disaster in slow motion,” states Kendra Boot, City Forester. “Since
EAB’s first detection in Colorado, we had the opportunity to plan and prepare for this pest, unlike other parts of the

state and country. As always, we will approach the management of this invasive pest thoughtfully and thoroughly,
while balancing the social, environmental and economic impacts that EAB will have on our resilient community.”
EAB tends to move slowly through natural spread and quickly through human transport. Now that EAB has been
detected in Fort Collins, it is important to keep all ash material in Fort Collins to prevent continued spread to other
communities.

Fort Collins residents with questions specific to EAB management on their property should contact the City of Fort
Collins Forestry Division, or a Fort Collins licensed tree care company listed at fcgov.com/forestry/arborists.
