The Smart Ash Superhero is making the rounds to local libraries, recreation centers and public spaces to introduce more Denverites to the Emerald Ash Borer (EAB) and ways to Be A Smart Ash. Be on the lookout for the Smart Ash display and let us know where you see him by tagging @BeASmartAsh or using the hashtags #EAB and #BeASmartAsh on Twitter.

Join our effort to save Denver’s ash trees by talking to your neighbors, friends and co-workers about EAB and encourage people to visit BeASmartAsh.org for more information.

The Emerald Ash Borer (EAB) was confirmed in the City and County of Broomfield, northwest of Denver, on Aug. 20, 2019 – the first confirmation of EAB in Colorado outside of the federal quarantine that primarily encompasses Boulder County.

A Broomfield resident familiar with the appearance of EAB due to Broomfield’s proactive public education campaign noticed a suspicious insect on their personal property near 136^th Avenue and Main Street and contacted the Broomfield city forester. It is not known whether the pest arrived by natural spread or human transport such as firewood.

At least 15% of all urban and community trees in Colorado are ash species susceptible to being killed by EAB. EAB attacks and kills both stressed and healthy ash trees and is so aggressive that trees typically die within two to four years after infestation. While EAB has not yet been detected in Denver, it could already be here.
