The Native Plant Master® Program fosters stewardship of native plants, sustainable landscaping, and management of alien invasive weeds that threaten native ecosystems. Impacts in the past six years were significant and included a total of 89,134 direct educational contacts made by 2,567 volunteers. The program is the only one of its kind in the country, and scholarly products include a curriculum, the Colorado plants database, educational manuals, and fact sheets to support student learning. NPM courses are field-based, and participants learn taxonomy, landscaping uses of native plants and noxious weed identification and control. Hands-on indoor classes are also offered.
