High Plains Arboretum

The High Plains Arboretum is a 62-acre collection of unique historic trees located on the former USDA Cheyenne Horticultural Field Station, west of Warren Air Force Base. Many hardy trees, shrubs, and flowers were tested here for survival on the High Plains. Researchers at the station also developed new varieties of plants that were suited to Cheyenne's harsh climate.

State Historic Site Project

In 2023, the city of Cheyenne invited the Wyoming State Parks Department to consider designating the High Plains Arboretum as a state historic site. This project would create a partnership between the city of Cheyenne, USDA, and Wyoming State Parks to cooperatively manage the site. The city would continue caring for the trees, the USDA would continue the grasslands research, and state parks would help preserve the historic buildings and improve visitor services. A bill designating the historic site will come before the Wyoming Legislature in January 2025.

A Brief History

The High Plains Arboretum is 62 acres of what was once woody plant research blocks as part of the 2,870 acre USDA Cheyenne High Plains Horticultural Research Station. From 1928 through the mid 1970’s the research station’s goals were to find, breed and release trees, shrubs and flowers that would survive in the challenging climate of the High Plains to further encourage settlement of the High Plains. With many successful plant introductions, it is one of the nation’s important historic horticultural sites.
