2/4/2014: Emerald ash borer survey locates more areas with infested ash trees in the city of Boulder; branch sampling reveals hidden pest
Emergency Quarantine Issued to Protect Colorado Ash Trees--Effective 11/12/2013
Emerald Ash Borer (EAB) was found in Boulder, CO, in September 2013. As a non-native insect, EAB lacks predators to keep it in check. EAB only attacks ash trees, and is responsible for the death of millions of ash trees in the midwest. Help protect Colorado's ash trees!
Colorado has many ash in the urban forest (we estimate about 15% of trees are ash). Ash trees are popular in Colorado with an estimated 98,000 in the city of Boulder alone; the Denver Metro area has an estimated 1.45 million ash trees.
If you think you have EAB in your ash trees, or if you have any questions or concerns, or would like additional information, please contact the Colorado Department of Agriculture at 888-248-5535 or email CAPS.firstname.lastname@example.org.
The Colorado Department of Agriculture and Colorado EAB Response Team is asking for feedback regarding the impact of EAB on you, your business or Agency and future planning and response needs. We hope as many people as possible will take the time to fill out this survey and share their opinions. All response is anonymous and will be used to guide future education, outreach, strategic planning and response. We want to make sure all views and stakeholders are represented in future planning activities. Select link above to participate in the survey.
