Summary

The Great Plains Landscape Conservation Cooperative (GPLCC, https://www.fws.gov/science/catalog) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support wildlife conservation [...]

Summary

The Great Plains Landscape Conservation Cooperative (GPLCC, https://www.fws.gov/science/catalog) is a partnership that provides applied science and decision support tools to assist natural resource managers conserve plants, fish and wildlife in the mid- and short-grass prairie of the southern Great Plains. It is part of a national network of public-private partnerships — known as Landscape Conservation Cooperatives (LCCs, http://www.fws.gov/science/shc/lcc.html) — that work collaboratively across jurisdictions and political boundaries to leverage resources and share science capacity. The Great Plains LCC identifies science priorities for the region and helps foster science that addresses these priorities to support wildlife conservation throughout the Great Plains region. It also assists partners in building their own capacity to address scientific challenges associated with our rapidly changing environment. These data were compiled because the information did not previously exist as a single resource for the GPLCC area. They are intended to inform local and regional conservation and management strategies with a complete regional perspective. Abstract provided by original data sources: "The U.S. Geological Survey (USGS) has generated and mapped isobioclimate classes for the contiguous United States. These isobioclimate classes were created as part of an effort to map standardized, terrestrial ecosystems for the nation using a classification developed by NatureServe (Comer and others, 2003). Ecosystem distributions were modeled using a biophysical stratification approach developed for South America (Sayre and others, 2008) and now being implemented globally (Sayre and others, 2007). Bioclimate regimes strongly influence the differentiation and distribution of terrestrial ecosystems, and are one of the key input layers in the ecosystem delineation process. The Rivas-Martínez methodology used to produce these classes was developed from a consideration of bioclimatology and its relationship to phytogeography (Rivas-Martínez, 2004; Rivas-Martínez and others, 1999, 2004). This approach develops a number of bioclimatic indices calculated from a variety of data on temperature and precipitation (e.g. average temperature of the coldest month, total precipitation of the warmest four-month period, a continentality index and a thermicity index). Daymet data, which was developed from 18-year (1980-1997) climatological records and is available at a spatial resolution of 1 kilometer, was used as the source data for these indices (Thornton, 1997). Once calculated the values of these indices are compared to established thresholds for the differentiation of thermotypic (warm/cold gradients) and ombrotypic (wet/dry gradients) regions, and the results are used in sets of decision rules to identify classes. The classification is implemented in four levels: macrobioclimates, bioclimates, thermotypes (thermoclimatic belts) and ombrotypes (ombroclimatic belts). The final isobioclimates dataset represents areas of the 127 unique thermotype-ombrotype combinations that were mapped for the contiguous United States." Data were the best available at the time of compilation (2011) with current information represented by a combination of national-scale datasets and state or other regional data (e.g. soils) that could be reasonably aggregated.

Purpose

This environmental dataset was one of several abiotic layers to provide best available conditions representing the landscape. The data collected and compiled for the Great Plains Landscape Conservation Cooperative (GPLCC) will inform regional-scale landscape assessments with spatially explicit representation of natural resource, habitat, conservation, management and other social and environmental values. Preliminary analyses will summarize spatial statistics, and data are ultimately expected to directly inform species and habitat distribution models and vulnerability assessments. Future research efforts applying these data may include regional hydrologic modeling, wetland habitat vulnerability and connectivity assessments, species distribution modeling, and investigation of interactions among land use, land cover and prairie habitat distributions. A simple summary of the data and discussion of potential applications and implications for future work (e.g., species distribution modeling and vulnerability assessments) will accompany the distribution of these data via the Great Plains Landscape Conservation Cooperative (GPLCC). Purpose provided by original data sources: "This dataset was created as part of an effort to map ecological system footprints for the contiguous United States."
