Boulder Celebrates Arbor Day While Recognized as ‘Tree City of the World’ by the Food and Agricultural Organization and Arbor Day Foundation

Friday, April 30 is National Arbor Day and on this day the City of Boulder celebrates its designation as a Tree Cities of the World for the second year in a row by the Food and Agriculture Organization of the United Nations (FAO) and the Arbor Day Foundation.

The international program celebrates cities that meet standards for the care and planning of urban trees and forests.

To be recognized as a Tree City of the World, the city met the five standards: establish responsibility, set the rules, know what you have, allocate the resources, and celebrate achievements.

The Tree Cities of the World program is built off the success of the Arbor Day Foundation’s Tree City USA program, which has provided recognition for more than 40 years.

“The city is honored to be a ‘Tree City of the World,’ and we hope this designation helps our community continue to create and protect our urban forest in the future,” said Forester Kathleen Alexander. “Our community needs to continue planting a diversity of trees because a healthy urban tree canopy is crucial to mitigating the effects of climate change.

In addition to this designation, the city was named “Tree City USA” for 36 consecutive years, including in 2020, and was awarded the Tree City USA Growth Award in 2018 by the National Arbor Day Foundation.

Boulder’s Urban Forestry department manages approximately 50,000 public trees in city parks and public street rights-of-way. City park and public street trees are inspected for health, structural integrity and safety using industry-set standards and techniques to facilitate the maintenance of a healthy and diverse urban canopy. The department plants approximately 300 trees in city parks and public street rights-of-way in both residential and commercial sites throughout the city every year.

Trees provide numerous benefits to a city when properly planted and maintained. They help remove air pollutants, improve physical and mental health, reduce home cooling and heating costs, reduce stormwater runoff, increase biodiversity, increase the community resilience to climate change, increase property values, and provide a wildlife habitat.

The city encourages community members to plant a tree and increase our urban canopy. If you would like a free tree planted into the public right-of-way adjacent to your home in spring 2022, please visit BoulderForestry.org and click on “Request a Street Tree.”
