Biographical history
James K. ""Tex"" Lewis was born on October 24, 1924, in Waco, Texas. He earned a B.S. in Animal Science from Colorado State University in 1948 and an M.S. in Animal Science from Montana State College in 1951, later pursuing graduate studies in range management at Texas A&M University.
As a professor of Animal Sciences at South Dakota State University, Lewis specialized in range management and range livestock nutrition. His research at the Cottonwood and Antelope Range Field Stations focused on grazing systems, supplementation trials, range improvements, and biometric analyses of grassland ecosystems. He was honored with several awards, including the Special Appreciation Award (1975), the Trail Boss Award (1980), and the Outstanding Achievement Award (1984) from the Society for Range Management.
Lewis retired from SDSU in 1985, leaving a lasting impact on the field of range science. His legacy continues through the long-term data he collected, which remains a valuable resource for contemporary research in sustainable rangeland and livestock management. Current studies analyzing stocking rates, forage productivity, and ecological sustainability continue to build on the foundational work Lewis conducted across South Dakota’s rangelands.
Content and structure elements
Scope and content
The James K. “Tex” Lewis Papers comprise research data, field notes, correspondence, publications, photographs, and teaching materials that document Lewis’s extensive range management research and instructional activities. The bulk of the materials pertain to Projects 216, 217, 239, and 421, long-running studies on forage production, grazing systems, livestock weight monitoring, and soil moisture dynamics conducted primarily at the Cottonwood Range Field Station, but also at Antelope Range Field Station, the Badlands, and other locations. The collection includes detailed observational and statistical data (e.g., point frame data, clip plot studies, Vegometer readings, and remote sensing imagery), climatological records, experimental livestock weights, soil analyses, and related environmental assessments. Boxes also include datasets used in simulation modeling (e.g., SPUR) and course materials for RANG, AS, and WL courses taught by Lewis.
Additional documentation reflects collaboration with national and regional entities such as the American Grassland Council, Society for Range Management, Great Plains Agricultural Council, and Bureau of Land Management. Also included are aerial photographs, GIS data, proposals, and internal reports, showcasing the depth and scientific rigor of Lewis’s methodology. Later series feature writings, technical guides, and training materials used in both academic and governmental range science settings.
This collection is a resource for understanding mid- to late-20th-century range science and ecosystem monitoring in the Great Plains. James K. Lewis’s work contributed significantly to innovations in grazing system design, range condition monitoring, and statistical modeling of range-livestock interactions. His leadership in integrating remote sensing, climatological data, and ecological classification methods helped shape contemporary range management practices. The materials are particularly valuable for researchers interested in the evolution of land use planning, sustainable grazing systems, and interdisciplinary range-livestock ecology. The inclusion of raw data and simulation outputs enhances the collection’s potential for longitudinal environmental and climatic studies.
