Collins Emerald Ash Borer (EAB) Management and Response Plan

Starting in 2013, the emerald ash borer (EAB) has been detected in Colorado, spreading throughout most of the North American ash (Fraxinus). The City of Fort Collins updated the tree inventory on public properties and aimed to treat 2,100 ash trees using pesticides (Emamectin benzoate) or mechanical removal, while replanting more resilient trees over a 3-year period. Public education and outreach will inform residents of new infestations, treatment options, and removal requirements, and encourage treatments on private properties. An integrated pest management approach will be implemented with the goal of balancing selective tree removal, chemical treatments, tree replacements, and continued efforts to provide core services.
