Donald B. Zobel was a faculty member in the Oregon State University Department of Botany and Plant Pathology from 1968 until his retirement in 2003. Zobel's research area was forest ecology; he worked on projects concerning the water relations of trees in the Himalayas and in North America and the recovery of plants buried by volcanic debris at Mount St. Helens.
William W. Chilcote was Professor of Botany at Oregon State University from 1950 to 1981.
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.
Collection is open for research.
The Zobel Collection of Historic Foresty and Vegetation Maps is arranged in five series: I. McDonald Forest, 1989; II. H.J. Andrews Experimental Forest, 1959-1969; III. Oregon Forest Maps, 1914-1980; IV. California Soil Vegetation Survey, 1950-1970; and V. Other Maps, circa 1915-1980.
Donald B. Zobel Collection of Historic Forestry and Vegetation Maps, Oregon State University Archives, Corvallis, Oregon.
The maps were donated to the OSU Libraries in 2008.
The OSU Archives' holdings include many other collections documenting
forestry in Oregon and the northwest. Other collections with significant
components of maps are the
Series I consists of an annotated map showing eco plots in the Soap Creek Tract of McDonald Forest; many of the plots include hemlock. An index map of the College of Forestry Research Forests is also included.
Series II consists of maps compiled and assembled for research on timber stands and watersheds in the H.J. Andrews Experimental Forest in the central Oregon Cascades.
Locations of recon plots by Jerry Franklin and Ted Dyrness in late 1960s annotated by Zobel with locations of
Maps at various scales including 1 cm = 1 m. Maps of the Hi-15 watersheds (watersheds 6, 7, and 8) and watershed 2 showing timber stand conditions. Also includes map showing vegetation sampling plots by Jerry Franklin and Ted Dyrness.
Stem map of one of the most intensively studied sites in the Andrews Forest. Mapping of trees, downed logs, and stumps was done by Glenn Hawk and others.
Series III consists of forest type and forest cover maps of portions of Benton and Polk Counties; maps from a cutbank stability reconnaissance survey in the Siskiyou National Forest; maps of fire protection districts in western Oregon; and other maps of Oregon forests. Of particular note are a 1914 Oregon map published by the Oregon State Board of Forestry and a 1921 map of national forests in Oregon and northern California.
Map scale 1:62,500. Also includes report by Richard J. Alvis, Soil Scientist with Division of Watershed Management, that outlines objectives, procedures, and limitations of study; cutbank stability classes; and erosion potential classes.
Scales of 1 inch = 1000 feet and 2 inches = 1 mile. Base maps prepared by U.S. Department to Interior Bureau of Land Management. Maps are hand-colored and annotated.

Published by the Oregon State Board of Forestry; compiled by Theodore Rowland under direction of F.A. Elliott, State Forester. Item is very brittle and fragile.
Series IV consists Soil Vegetation Maps, Timber Stand Vegetation Cover Maps, and legends and supplementary information created as part of the California Soil Vegetation Survey during the 1950s and 1960s. The soil vegetation maps are of Humboldt County; the timber stand vegetation cover maps depict areas of both Humboldt and Del Norte Counties. All maps are at a scale of 1:31,680. The California Cooperative Soil-Vegetation Survey documented the types of upland soils and the natural cover of trees, shrubs, grasses, and other vegetation. It was a joint project of the California Division of Foresty, the University of California, and the U.S. Forest Service Pacific Southwest Forest and Range Experiment Station.
Series V consists of non-forest maps of Oregon as well as forest and vegetations maps of areas other than Oregon. These include forest type maps for midwestern states prepared by the North Central Forest Experiment Station of the U.S. Forest Service. Of special note are a 1962 road map for the Warm Springs Indian Reservation and a 1925 topographic map of the Three Sisters, Oregon.
