Funding for the arboretum is provided by the Colorado Nursery Research and Education Foundation (CNREF), GreenCO Foundation, the Colorado Agriculture Experiment Station (CAES), and Colorado State University Extension. The operation and maintenance of the arboretum and the collection of evaluation data would not be possible without the help of the research associates and students who have worked as employees and volunteers over many years. Many public and private organizations have provided funding and donated plant material and supplies to the arboretum through the years.

We would like to thank those listed below for their support and donations:
