OpenTreeMap has been a great tool for us to generate excitement about trees, broaden interest in the urban forest, and involve community members ranging from college students to neighborhood groups.

OpenTreeMap tells the story of each city’s urban forest like no other tool out there right now.
—Philip Silva and Liz Barry, TreeKIT Co-Founders
As chair of the Asheville Tree Commission, whenever I am asked to make a presentation to a group, I show them Asheville's Tree Map. It's an exciting way to get people engaged with tree issues, and the user-friendly interface seems to inspire people to check it out. For anyone interested in learning about the environmental and financial benefits of trees in the Asheville area, it's an exceptional tool.
—Mike Kenton, Certified Arborist and Chair, Asheville Tree Commission
