Within grassland communities of the GPLCC one such key indicator species is the Lesser Prairie-chicken (Tympanuchus pallidinctus). Lesser Prairie-chicken range extends across the southern portion of the GPLCC area throughout Texas, Oklahoma, New Mexico, and Kansas. Lesser Prairie-chickens are a good target species because they are widely distributed across the southern GPLCC, are a species of conservation concern, have large home ranges, and are likely sensitive to anthropogenic disturbances. Similarly, the Greater Prairie-chicken (Tympanuchus cupido), is a species of conservation concern, with large home range, distributed across the northern portion of the GPLCC including portions of Oklahoma, Kansas, Nebraska,...

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

This digital geospatial compilation gathered paleoflow indicators from current-formed sedimentary structures throughout the Paleozoic Ozark uplift, Arkoma foreland basin, and Ouachita fold-thrust-belt of eastern Oklahoma and western Arkansas from existing publications. This dataset consists of unidirectional and bidirectional paleocurrents observed from a variety of bedform types represented by approximately 9,958 individual measurements and 665 calculated means (one .csv file) plotted as points (one .shp file) with subordinate Ordovician-Silurian and primarily Mississippian-Pennsylvanian ages.
Summary of project, results, and discussion for the study completed by David J. Augustine, Willam E. Armstrong, Jack F. Cully, and Michael F. Antolin. Summary written by the Great Plains Landscape Conservation Cooperative (GP LCC).

This layer was created by selecting classes relevant to conservation of the grassland-prairie-savanna broadly defined habitat from the LANDFIRE Existing Vegetation Type (evt) spatial data product clipped to the boundary of the GCPO LCC. The layer was generated as in input layer for the Draft Grassland Condition Index raster data layer in support of the GCPO LCC rapid ecological assessment of the Grassland-Prairie-Savanna Priority Habitat. In selecting vegetation types, “grasslands” were defined as any landscape dominated by grass, excluding classes considered to be features of other priority habitats, such as marshes, dunes, glades, woodlands, and pine savanna. The 44 selected grassland classes included pasture/hay...

We flew aerial line transect surveys between March 30 and May 3, 2012, to estimate the abundance of lesser prairie-chickens (Tympanuchus pallidicinctus) and lesser prairie-chicken leks in four habitat regions in the Great Plains U.S. Estimates were supplemented with data from surveys conducted by Texas Tech University in two regions in the Texas Panhandle and surveys conducted by the Oklahoma Department of Wildlife Conservation in Oklahoma. We also estimated the number of mixed species leks which contained both lesser and greater prairie-chickens (Tympanuchus cupido) and the number of hybrid lesser-greater prairie-chickens. The study area for 2012 included four regions containing the 2011 estimated occupied lesser...

We developed multi-scale habitat suitability models for black-tailed prairie dogs (BTPD) in the southwestern Great Plains, corresponding to the western region of the Great Plains LCC. We used long-term (10-yr), high-resolution datasets on BTPD colony boundary locations collected at 7 study areas distributed across the region to develop resource selection functions based on colony locations and expansion patterns. Models are based on (1) soil maps and associated Ecological Sites (NRCS SSURGO database), (2) a topographic wetness index based upon water runoff and solar insolation patterns (TWIsi) that tests a priori hypotheses for topographic controls on BTPD, and (3) broad climatic gradients in temperature and mean...

The black‐tailed prairie dog (Cynomys ludovicianus) is considered an indicator species for the short grass prairie of North America; however, this species currently occupies an estimated 2% of its original distribution. Persistent and pervasive poisoning, and sylvatic plague have fragmented the remaining populations. It is not well understood how these population fragments are connected in a heterogeneous landscape of land use practices and land cover types, but quantifying population isolation and individual measures of dispersal across the landscape are essential to predicting both the vulnerability of extinction due to stochastic processes and the probability of disease emergence. To better understand how land...

The dataset consists of abundance information of butterfly species (61 species) collected at 25 sites in northwest Indiana in 1998 and 1999. Each site was surveyed 21 times. Auxiliary data on environmental conditions were collected to allow us to relate habitat differences among sites to differences in abundance and composition of the butterfly community.
