Citywide Tree Pruning and Removal Scheduled for October 2018 Through March 2019
Trees are inspected annually for structural integrity and safety
The City of Boulder’s Parks and Recreation Department will have a contractor prune 95 trees and remove 332 trees in city parks and street rights-of-way over the next six months. Tree maintenance work will begin in October 2018 and is scheduled through March 2019.
The Parks and Recreation Department’s Urban Forestry Division manages about 50,000 public trees in city parks and street rights-of-way. City park and public street trees are inspected annually for structural integrity and safety using industry-set standards and techniques. Urban Forestry staff is conservative when determining if a tree must be removed. Trees are removed due to structural concerns, poor health or if they are diseased/infested with Emerald Ash Borer (EAB). Factors that go into the risk assessment are tree species, size, defect and target, as well as what the tree would hit if it fell. This procedure is part of sustainable city practices that facilitate the maintenance of a healthy and diverse urban canopy.
Of the 332 trees identified for removal, 168 trees are ash trees impacted EAB. Many of the trees will be replaced through Urban Forestry’s tree planting program or park development projects.
EAB, an invasive wood boring beetle, attacks all North American ash (Fraxinus spp.) not protected by pesticides. Now present in 30 other states, EAB has killed hundreds of millions of ash trees over the past two decades. All public and private ash trees in Boulder are currently at risk. Declining public and private ash trees will require removal before they present an unacceptable level of risk to public safety. As EAB populations in Boulder continue to increase, ash trees are expected to die at an accelerated rate. Residents can expect to see increasing numbers of ash tree removals over the next few years.

Tree work along public street rights-of-way may require temporary lane closures or traffic detours. Flaggers will be on site to ensure public safety and to guide pedestrians through work zones.
The city would like to remind residents that if you are contracting the removal of a tree on your property, make sure you are using a tree care company licensed through the City of Boulder. The list of licensed arborists is found on Bouldercolorado.gov.
