Colorado App Identifies Emerald Ash Borer Threats

Golden, CO (June 7, 2017) – To help Colorado homeowners determine whether trees on their property are susceptible to being killed by emerald ash borer (EAB), the Colorado State Forest Service and Colorado State University Extension released a free app which allows anyone to use their mobile device to quickly ascertain whether a tree may be a potential target for the pest.

EAB is a highly destructive, non-native insect from Asia, first detected in Colorado in 2013, which is fatal to all infested ash trees unless the trees have been chemically treated.

“The most important thing Colorado communities can do now is prepare for emerald ash borer’s arrival by increasing their EAB awareness, sharing information about how to identify ash trees and learning the symptoms of this pest,” said Keith Wood, CSFS community forestry program manager.

The EAB/Ash Tree ID app can be downloaded on almost any Apple or Android-based device, and easily located in app stores by simply searching for “ash tree.” It offers a step-by-step process to determine if a given tree appears to be a true ash or not, and offers links and other information about EAB for users who suspect they might have an ash tree, including homeowners, business owners, school groups or anyone concerned about the potential impacts of this pest.

The app also is intended to prompt homeowners and other landowners to consider early management options for EAB. These may include replacing unhealthy trees before they die, treating high-value trees with the proper insecticides and planting new trees near ash that might ultimately succumb to the pest.

EAB, which is responsible for the death of tens of millions of ash trees in 30 states and two Canadian provinces, has only been detected in Boulder County within Colorado. Yet the pest has become a concern for communities all over the state because each year it can fly up to a half mile to infest new trees, and spread much faster through the human transport of firewood and other raw wood. An estimated 15 percent or more of all urban and community trees in the state are ash, which are susceptible to EAB.

Boulder and Longmont have been dealing with the pest’s impacts since having confirmed detections, while many other Colorado communities are preparing for EAB’s arrival. The City of Denver began its “Be a Smart Ash” campaign last year to raise awareness of the EAB threat in the metro area, where one in six trees are ash, and since then has been implementing a 15-year plan to identify, treat and replace ash trees on city property.
