The Royal G. Jackson Papers consist of materials created or assembled by Jackson in the course of his research. The bulk of the materials pertain to the history of the Oregon State University College of Forestry, McDonald – Dunn Research forest, the Civilian Conservation Corps (CCC) Camp Arboretum, and nature-based tourism in central Oregon and Costa Rica. The papers include extensive oral history sound recordings and photographs, in addition to manuscripts, publications and reference materials. Jackson was a faculty member in the Oregon State University College of Forestry from 1970 until 2004.
The McDonald Forest and Peavy Arboretum Maps consist primarily of detailed maps of the Arboretum and Forest prepared from the mid-1930s through early 1940s. The maps document topography, forest site and timber types, and plantings in the Arboretum. Peavy Arboretum and McDonald Forest were established in the 1920s as a teaching laboratory and experimental forest for the forestry students at Oregon State College.
