Scope and Content Note
The Donald B. Zobel Collection of Historic Forestry and Vegetation Maps consists of maps assembled, annotated, or created by Zobel for his research and teaching in forest ecology and botany. Some of the maps were assembled by William W. Chilcote, his students, and other Botany Department faculty. Most of the maps are of Oregon, including McDonald Forest and the H.J. Andrews Experimental Forest, and northern California. However, the collection includes maps of forest types in midwestern states, a vegetation map of North America, and map of initial damage from the May 1980 eruption of Mt. St. Helens, Washington.
The primary topics addressed by the maps are forest types, forest and vegetation cover, timber stands, soils and erosion. These include maps of a cutbank stability reconnaissance survey in the Siskiyou National Forest in the 1960s, the California soil vegetation survey in the 1950s and 1960s, and research on the H.J. Andrews Experimental Forest by Jerry Franklin and Ted Dyrness in the 1960s. The collection also includes general purpose forest, recreation, and topographic maps. Of particular note are a map of the of road system on the Warm Springs Indian Reservation (1962); a topographic map of the Three Sisters, Oregon, prepared by Edwin T. Hodge (1925); and a 1914 maps of the state of Oregon published by the Oregon State Board of Forestry. A map of the vegetation of North America prepared by John W. Harshberger in the 1910s is also included.
The collection includes maps prepared by the Oregon State University College of Foresty and OSU Research Forests; the U.S. Forest Service; the Oregon Department of Forestry; the U.S. Department of Interior, Bureau of Land Management, and U.S. Geological Survey; and the California Division of Foresty.
