Emerald Ash Borer: What Colorado Communities Need to Know
April 21, 2014
With the highly destructive emerald ash borer (EAB) now confirmed in Colorado, many homeowners have questions about their ash trees and the risks presented by the invasive tree insect.
Late last year EAB was detected in the City of Boulder.
The insect is already responsible for the death or decline of tens of millions of ash trees in more than 20 states. It poses a serious threat to many of Colorado’s urban forests, where ash species comprise an estimated 15-20 percent of all trees.
To help homeowners and communities make decisions about dealing with the pest, the Colorado State Forest Service recently released a new Quick Guide about EAB in Colorado.
Current Recommendations for Colorado:
For more information about EAB infestation, treatment options and ash tree identification, view the EAB Quick Guide online or pick up a free copy at the nearest CSFS district or field office.

LAKEWOOD, Colo. –An invasive insect responsible for the death or decline of tens of millions of ash trees in 21 states has been detected in Colorado for the first time.

“The confirmation of these specimens as emerald ash borer (EAB) marks the western-most occurrence of this invasive pest in North America,” said Patrick McPherren, USDA State Plant Health Director in Colorado. “To date Colorado is the fourth State to detect EAB in 2013.” Read More>>
