These data provide information about the point-centered quarter measurements taken to calculate distance to the nearest shrub and shrub density for random vegetation transects.

Field crews from Northern Prairie Wildlife Research Center from 1991-1993 in Stutsman County, North Dakota and Pope and Stevens Counties, Minnesota, gathered nest success and fledgling data from nests found within Conservation Reserve Program fields and Waterfowl Production Areas. This dataset includes nesting observations of bird species found within these two field types. The dataset includes genus and species, vegetation height, distance to edge and perch, host nesting and fledgling variables, and parasitic nesting and fledgling variables.

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....

These data include descriptions of all roadside segments surveyed, including GPS waypoints and verbal descriptions for each point (every half mile), survey data collected on roadside surveys in 2003-2005 in the months of July and August, along roads within the known breeding range of the Arizona Grasshopper Sparrow (Ammodramus savannarum ammolegus).

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...

Mean flea counts from prairie dogs and their burrows in Utah (2000), New Mexico (2010–2012), and Montana (2016, 2019). Prairie dogs were live-trapped, anesthetized with isoflurane, and combed thoroughly for 30 or 45 seconds to remove and count fleas. Prairie dogs were allowed to recover from anesthesia and released at their trapping locations. Randomly selected prairie dog burrows were swabbed for fleas using a plumber’s snake to insert a white flannel-cloth as deep as possible into each tunnel; the cable was shook ~30 seconds, and the cloth was removed from the burrow and quickly sealed in a re-sealable zipper storage bag. Fleas were later removed from swabs and counted. Mean flea counts were calculated for each...
This dataset contains vegetation data collected at a variety of watershed restoration sites across southeastern Arizona over 5 years. The semiarid habitats in the Madrean Archipelago Ecoregion, which extends from southern Arizona into northern Mexico, are facing many challenges from climate change to land use change which threaten the ecological and cultural values of the region. Watershed restoration practitioners use a variety of techniques such as gabions, check dams, and cross vanes to reduce the effects of these threats and improve or maintain watershed function. Since vegetation dynamics in the area are driven by water availability, these restoration techniques appear to have secondary effects on the vegetation...

These data (all data tables for the data release) represent a suite of biotic and abiotic variables that characterized plant communities and the geologic, geomorphic, edaphic, climatic, and land use history context in which distinct plant communities occur. In 2009, the National Park Service's Inventory and Monitoring program for the Northern Colorado Plateau Network (NCPN) began measuring vegetation cover and site characteristics at monitoring plots stratified across different vegetation types within national parks on the Colorado Plateau. NCPN biologists remeasured vegetation cover at these plots in a rotating panel over the following decade. In 2019, U. S. Geological Survey geologists and soil scientists collected/compiled...

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...

The U.S. Geological Survey and Desert Research Institute, in cooperation with the Natural Resources Conservation Service, Texas State Soil and Water Conservation Board, Victoria County Groundwater Conservation District, Victoria Soil and Water Conservation District, and the San Antonio River Authority, evaluated the hydrologic effects of Vachellia farnesiana var. farnesiana (huisache) removal on rangeland evapotranspiration in Victoria County, Texas. Measurements of evapotranspiration (ET), rainfall, and related properties were made at two sites during March 2015 through August 2018. One site was predominately grassland. The other site was dominated by dense huisache vegetation that was removed about halfway through...

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.

Data included in this data set are from in-field and edge-of-field surveys that recorded the presence of erosional features and cover of vegetation and bare ground on 1786 Conservation Reserve Program fields across three types of conservation practices (grassland, wetland, and wildlife). Field sampling data were recorded across six US Department of Agriculture Farm Production Regions (Corn belt, Lake states, Mountain, Northern plains, Pacific, Southern plains) from 2016 to 2018. The study area encompassed all or part of 14 states: Washington, Oregon, Idaho, Montana, North Dakota, South Dakota, Minnesota, Iowa, Missouri, Colorado, Nebraska, Kansas, Oklahoma, and Texas. These data constitute the first national level...

These data provide information about all vegetation structure measurements (except shrub point-centered quarter measures) taken on Arizona Grasshopper Sparrow territories in 2009 to 2013 on two study sites - Audubon Appleton-Whittell Research Ranch, and BLM Las Cienegas NCA - Davis Pasture - in southeastern Arizona.
