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.
The major activities supported by this grant focused on decommissioning the SGS-LTER program to curate and make openly available digital data and information, complete and disseminate scientific findings, and develop infrastructure upon which new research studies, and educational and outreach activities can be proposed and/or developed for the future. Scientific objectives related to compiling and analyzing long-term datasets, using long-term datasets in modeling efforts and publishing results. Information management objectives focused on packaging data and metadata for ingestion into the LTER Network Information System (LTER NIS) Provenance Aware Synthesis and Tracking System (PASTA), and creating an inventory of archived samples for use in the future. Objectives to have access to an information infrastructure from the SGS-LTER project and maintain partnerships within the local ecological research community were met by researchers and educators and we report in more detail on our approaches and accomplishments in the final progress report.
