Benefits of Trees
Read more about how Boulder’s urban forest provides many environmental benefits to our community. Aside from the obvious aesthetic benefits, trees within our urban forest improve our air, protect our water, save energy, improve economic sustainability, and provide food and shelter for wildlife.
Branching Out Boulder
We invite you to have a meaningful conversation about trees – our trees. The trees that line our streets and beautify our parks. Our goal is to create a successful outreach effort by the City Forestry Division, using conversation and feedback about the future of Boulder’s city trees as a foundation for the creation of Boulder’s Urban Forest Strategic Plan.
Boulder’s Parks and Recreation Department will complete a broad scope Urban Forest Strategic Plan in 2016/2017. The plan will capitalize on the recently completed public tree inventory and make recommendations for urban tree management for city parks and street rights-of-way.
Emerald Ash Borer
Emerald Ash Borer (EAB) is a green jewel beetle that feeds on ash tree species. In the U.S., EAB is a federally quarantined, invasive tree pest responsible for the death or decline of more than 50 million ash trees to date. City of Boulder forestry staff identified an infected ash tree in northeast Boulder on Sept. 23, 2013
About 4,500 public trees will have to be removed in Boulder due to EAB. We are working to keep as much of this wood out of landfills as possible through the Tree Debris to Opportunity (TreeOpp) program.
