Shortgrass Steppe Long Term Ecological Research (SGS-LTER), author

Journal Title

Volume Title


The Central Plains Experimental Range long term ecological research project was first funded in 1982. In the past 11 years, the project has supported a large number of studies. Since nearly all of these studies are long-term in nature, it is appropriate to summarize not only new activities, but also the continuing projects within the research program. We have organized our report into 5 key areas: Core Area Research, Synthesis Activities, Current International Collaborations, Interactions with other Projects, and Data Management.


The SGS-LTER research site was established in 1980 by researchers at Colorado State University as part of a network of long-term research sites within the US LTER Network, supported by the National Science Foundation. Scientists within the Natural Resource Ecology Lab, Department of Forest and Rangeland Stewardship, Department of Soil and Crop Sciences, and Biology Department at CSU, California State Fullerton, USDA Agricultural Research Service, University of Northern Colorado, and the University of Wyoming, among others, have contributed to our understanding of the structure and functions of the shortgrass steppe and other diverse ecosystems across the network while maintaining a common mission and sharing expertise, data and infrastructure.
