Peavy Arboretum's origins trace back to the mid-1920s when the Oregon Agricultural College (now Oregon State University) School of Forestry recognized the need for an accessible outdoor laboratory for its students. Named in honor of Dean George W. Peavy, the arboretum was dedicated in 1926, initially encompassing 80 acres and serving as a classroom, research facility, and demonstration forest. From 1925, it also housed the Clarke-McNary State Nursery, producing seedlings for farmers and reforestation efforts. A significant chapter in its history was the establishment of a Civilian Conservation Corps (CCC) camp at the arboretum from 1933 to 1942. CCC workers played a crucial role in shaping the landscape, constructing many of the trails and roads still in use today, expanding the nursery, and building Cronemiller Lake (now Randal Pond) for irrigation. Before Euro-American settlement, the land where Peavy Arboretum stands was utilized by the Kalapuya people for at least 10,000 years, highlighting its long-standing ecological and cultural significance.
