The Village of Ashwaubenon was awarded Tree City USA for the 23rd consecutive year in 2015. Tree City USA is a nationally recognized program sponsored by the National Arbor Day Foundation in cooperation with the National Association of State Foresters, USDA Forest Service, U.S. Conference of Mayors, and National League of cities. The Tree City USA Program is designed to recognize those communities that effectively manage their public tree resources, and to encourage the implementation of community tree management based upon four Tree City USA minimum standards. The standards are:
- A tree board or department
- A community tree ordinance
- A community forestry program with an annual budget of at least $2 per capita
- An Arbor Day observance and proclamation
These four standards provide structure for a community forestry program, require the program to demonstrate success based on the judgment of the state forester's office, and provide for awareness and appreciation of trees among residents of the community.
