The Semi-Arid Grasslands Research Center
A partnership between CSU and the USDA Agricultural Research Service
The Semi-Arid Grasslands Research Center (SGRC) is adjacent to the USDA ARS-Central Plains Experimental Range (CPER), established in 1937 after the Dust Bowl to study grazing management practices.
The nearby Pawnee National Grassland provides ample opportunities for bird-watching, hiking, biking, or horse-back riding at the Pawnee Buttes and other backcountry locations, and other recreational activities.
CPER, a 15,500-acre research site, is the primary experimental range for USDA ARS in the Western Great Plains. It has hosted several large interdisciplinary network research programs for which the Colorado State University now curates digital collections of images, data and information. In 1964, the International Biome Program (IBP) established its grassland biome headquarters at the CPER. A collection of IBP technical reports is available online. In 1982, CPER became the core research site for the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project funded by the National Science Foundation until 2014. A digital collection of over one hundred SGS-LTER datasets is publicly.
Research and Engagement
Today, CPER, is the key grazing lands research site for implementation of a Collaborative Adaptive Rangeland Management (CARM) project. The CARM project exemplifies co-production of science with stakeholders participating in a common experiment as part of the USDA Long-Term Agroecosystem Research (LTAR) Network.
Researchers, K-16 teachers, and students have continuously studied and visited the area, and the mission of the SGRC is to provide state-of-the-art facilities to further support research and education, and to foster appreciation and understanding of the western Great Plains grasslands of North America.
