Creator: Hormay, August Ludwig, 1907-


Provenance Note: This collection was donated to Special Collections by the estate of August "Gus" Ludwig Hormay, 2003.


Historical Note: August "Gus" Ludwig Hormay (1907-1999) developed rest-rotation grazing systems for the management of rangelands in the Western United States during more than seventy years of work in natural resource conservation. After completing his academic studies at the University of California, Berkeley, Hormay began working for the United States Department of Agriculture Forest Service, in 1931. During the next thirty-six years, he worked out of the Pacific Southwest Forest and Range Experiment Station in Berkeley, California, primarily concerned with the management of rangelands in national forests of northeastern California. During this period, he developed a theory of rest-rotation that asserts proper livestock grazing allows the land to "rest" in cycles. This resting of rangeland produces and maintains the highest possible yields of renewable rangeland values. In 1966, Hormay transferred to the Bureau of Land Management in the United States Department of the Interior, where he spearheaded a program educating government officials, land stewards, and livestock-holders in rest-rotation grazing techniques. He retired from government service in 1977, but continued to advise interested parties in rangeland management as a consultant.


Content Description Note: The papers document the life and career of Hormay. They include extensive outgoing and incoming correspondence, in addition to calendars and diaries that document his daily activities, 1930-1999. There are also copies of his numerous publications on range management topics. Other components of the collection include research files on several national forests in northern California, including Modoc National Forest, Lassen National Forest, and Plumas National Forest, 1931-1993. The papers contain especially rich documentation of Lassen National Forest and the experimental forests and ranges therein, such as Blacks Mountain Experimental Forest, Burgess Spring Experimental Range, and the Harvey Valley Grazing Allotment. Extensive documentation exists for numerous grazing allotments and rangelands throughout the intermountain and Trans-Mississippi West analyzed and visited by Hormay, primarily 1965-1977. Hormay also completed hundred of experiments concerned with the reproduction and germination of bitterbrush (Purshia tridentata), 1942-1979. A relatively small portion of the collection documents the family life of Hormay, including photographs of his family and his home in San Francisco. Photographs and transparencies extensively document the work of Hormay in the national forests of northeastern California and rangelands throughout the western region of the United States.
