PLAY Boulder is leveraging the City’s efforts by planting and protecting an additional 1,000 trees over the next decade!  We are starting with a goal to raise $50,000 to plant 100 more trees than the City is scheduled to plant next year.

Join the 'Kiss My Ash' Campaign!

We are teaming up with McGuckin Hardware to promote the Tree Trust. Visit McGuckin today to purchase your exclusive Kiss My Ash shirt. All proceeds go directly to supporting tree plantings to replace EAB infested trees.       

The discovery of Emerald Ash Borer (EAB) in 2012 places more than 75,000 City of Boulder trees at risk.  EAB is an invasive pest threatening ash trees, which make up over 12% of Boulder’s urban canopy. Without treatment, infected ash trees will die within 5-7 years. The City is aggressively working to manage this challenge through treatment, removals and new plantings but cannot do it alone.   Though the City of Boulder has increased its forestry budget to aid in treatments and plantings, it will not be enough.

  • Boulder’s urban forest is a legacy that was largely created by the tree planting and stewardship efforts of previous generations. With the exception of trees native to the streamside corridors, Boulder’s trees were planted and tended by residents who valued the trees shade and beauty.  Their vision contributed to one of the many reasons we all love Boulder today.
  • The city’s urban forest is one of the few city assets that appreciate in value over time. Trees are not a luxury - they provide nearly $5.2 million in annual environmental, economic, and social services benefits ($50.39 per capita, an average of $102.48/tree) through air quality improvements, energy savings, stormwater runoff reduction, atmospheric CO2 reduction, and aesthetic contributions to the social and economic health of the community.
  • Ash is one of the most abundant tree species in Colorado comprising approximately 15% of all deciduous trees in many urban areas and approximately 12% in the City of Boulder.
