Volume Title


The Central Plains Experimental Range (CPER) Long Term Ecological Research (LTER) project focused on spatial and temporal patterns of ecosystem structure and function at the CPER in northcentral Colorado. Research was concentrated in 5 areas: soil water; primary production; population dynamics; organic matter accumulation and nutrient dynamics; and disturbances. We produced exciting results in each of these 5 areas and significantly changed the state of knowledge about the origin and sustainability of shortgrass steppe ecosystems.


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.
