Establishing connections among natural landscapes is the most frequently recommended strategy for adapting management of natural resources in response to climate change. The U.S. Northern Rockies still support a full suite of native wildlife, and survival of these populations depends on connected landscapes. Connected landscapes support current migration and dispersal as well as future shifts in species ranges that will be necessary for species to adapt to our changing climate. Working in partnership with state and federal resource managers and private land trusts, we sought to: 1) understand how future climate change may alter habitat composition of landscapes expected to serve as important connections for wildlife,...

Defining the pre-European range of vegetation communities can enhance our understanding of the role soil, hydrology, and climate had on climax plant communities within southwest Louisiana. Coastal prairie grasslands were in a perpetual state of succession due to two primary disturbances; grazing, primarily by bison and other ungulates, and fires ignited by lightning and Native Americans. Along its borders, prairie vegetation blended into adjacent plant communities forming biologically diverse ecotones that may have fluctuated between a prairie, marsh, or forest dominated community as a result of variable conditions including climate cycles, disturbance and soil characteristics. Since European settlement, this landscape...

This database contains records of grassland bird abundance and vegetation structure on tallgrass and mixed-grass prairies managed by the U.S. Fish and Wildlife Service (USFWS). Specifically, under the adaptive-management decision framework (Native Prairie Adaptive Management [NPAM] intiative), we surveyed breeding birds and sampled vegetation on 89 native prairie NPAM units managed by the U.S. Fish and Wildlife Service, including 55 units in 2011, 87 units in 2012, and 87 units in 2013. The NPAM units occurred in 19 USFWS refuge complexes and wetland management districts, including 14 complexes in USFWS Region 6 (North Dakota, South Dakota, and Montana) and five complexes in USFWS Region 3 (Minnesota).

Plant and soil data were collected in experimental plots in two sites ("Terrace" and "Hilltop") at Wind Cave National Park, South Dakota, and one site ("BSV") at Badlands National Park, South Dakota. At each site, 70, 2.5 x 2.5 m plots were assigned randomly to nitrogen-alone or nitrogen+water addition treatments (or no treatment for the control). Treatments were applied and data collected 2010-2013. The dataset includes six tables: (1) experimental treatments by plot and year; (2) plant and soil metrics analyzed in the larger work; (3) plant tissue and soil total carbon and nitrogen raw data; (4) plant biomass raw data; (5) canopy and ground cover raw data; and (6) canopy and ground cover codes.

This dataset describes features of 2941 duck nests that were found in the Prairie Pothole Region of North and South Dakota during 2002-2003. Nest features include estimated initiation date, incubation stage and status as active. The dataset accompanies a scientific journal article describing an evaluation of the density and success of duck nests in conservation fields in 36 study areas that were seeded with native or tame grasses. Field features in this dataset include seeding treatment, planted area, and area of grassland patch.

These data include nest-specific information about Arizona Grasshopper Sparrow nests monitored during 2011 to 2013. The data are formatted as we used them in Program MARK to evaluate factors affecting daily nest survival. Data includes information on when the nest was found, when it was last known to be active, nest fate, and nest age. In addition, we provide vegetation data from the nest site itself and the nest plot as well as summary seasonal precipitation data collected from other sources and used in these analyses.

The purpose of this project was to map the estimated distribution of grassland communities of the Southern Great Plains prior to Euro-American settlement. The Southern Great Plains Rapid Ecoregional Assessment (REA), under the direction of the Bureau of Land Management and the Great Plains Landscape Conservation Cooperative, includes four ecoregions: the High Plains, Central Great Plains, Southwestern Tablelands, and the Nebraska Sand Hills. The REA advisors and stakeholders determined that the mapping accuracy of available national land-cover maps was insufficient in many areas to adequately address management questions for the REA. Based on the recommendation of the REA stakeholders, we estimated the potential...
Soil P transformations and distribution studies under water limited conditions that characterize many grasslands may provide further insight into the importance of abiotic and biotic P controls within grass-dominated ecosystems. We assessed transformations between P pools across four sites spanning the shortgrass steppe, mixed grass prairie, and tallgrass prairie along a 400-mm precipitation gradient across the central Great Plains. Pedon total elemental and constituent mass balance analyses reflected a pattern of increased chemical weathering from the more arid shortgrass steppe to the more mesic tallgrass prairie. Soil surface A horizon P accumulation was likely related to increased biocycling and biological mining....

This dataset is North American Breeding Bird Survey bird-count data for the routes and stops in North Dakota, USA, in which ten mixed-grass-prairie-endemic species occurred, as well as the mean habitat-quality ranking scores derived from applying the Habitat Quality Module of the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) to spatial layers for landuse/landcover from the National Agricultural Statistics Survey, CRP from USDA, urban and road areas from US Census Bureau (Tiger/Line), and energy development from USGS. The bird-count data is the total sum of counts for the focal ten species; individual species counts are not part of the dataset.
This data release contains breeding-bird densities in native mixed-grass prairie collected from 2003 to 2012 at and adjacent to wind farms in North and South Dakota, USA, for one year prior to turbine construction and several years post-construction. One dataset contains breeding-bird densities per 100 ha by distance from turbines for categories of 0-100 m, 100-200 m, 200-300 m, and greater than 300 m from turbines and for reference (i.e., control) sites. A second dataset contains breeding-bird density overall for turbine and reference sites, without the distance-category breakdown. A third dataset contains measurements that characterize average vegetation structural measurements on each study plot. This data release...
