The Ash destroying Emerald Ash Borer (EAB) has been found both in Broomfield and Westminster for the first time since a quarantine zone was set up in 2013 in Boulder County after the EAB was found near the University of Colorado campus. The quarantine zone included Boulder, Gunbarrel, Longmont, Lafayette, Lyons and Superior. An alert homeowner in Broomfield noticed the borer on their property and contacted authorities. The City of Westminster confirmed the discovery of insect presence EAB near 128th Avenue and Zuni Street on September 11, 2019. Westminster is 9 miles from the Colorado State Capitol. The Colorado Department of Agriculture and the Colorado State University confirmed that it was the EAB.
Experts debate on how the EAB got to Broomfield and Westminster, whether it naturally migrated or if human action is to blame. “The borer can fly about a half mile each year,” said James Kadlubar, the Plant Health Care Manager at Ross Tree Company. “However, someone living in quarantine zone sharing infected Ash-tree firewood with someone outside of Boulder could be the culprit. We will never know how it got to Broomfield and Westminster.”
Kadlubar adds, “The EAB is here to stay. The EAB seems to spread no matter what state agriculture departments across the country try to do. This highly destructive pest has killed hundreds of millions of Ash trees east of the Mississippi.” Kadlubar says that homeowners first need to decide if their Ash trees are worth saving. Considering mature trees can account for up to 10% of a property’s value, he thinks that they are worth saving. “The logical decision is to cull any weakened Ash trees and try to save the rest,” Kadlubar says.
