Maintaining the native prairie lands of the Northern Great Plains (NGP), which provide an important habitat for declining grassland species, requires anticipating the effects of increasing atmospheric carbon dioxide (CO2) concentrations and climate change on the region’s vegetation. Specifically, climate change threatens NGP grasslands by increasing the potential encroachment of native woody species into areas where they were previously only present in minor numbers. This project used a dynamic vegetation model to simulate vegetation type (grassland, shrubland, woodland, and forest) for the NGP for a range of projected future climates and relevant management scenarios. Comparing results of these simulations illustrates...

The distribution of the greater sage-grouse (hereafter sage-grouse; Centrocercus urophasianus) has declined to 56% of its pre-settlement distribution (Schroeder et al. 2004) and abundance of males attending leks has decreased substantially over the past 50 years throughout the species’ range (Garton et al. 2011, Garton et al. 2015, WAFWA 2015). Livestock grazing is a common land use within sage-grouse habitat, and livestock grazing has been implicated by some experts as one of numerous factors contributing to sage-grouse population declines (Beck and Mitchell 2000, Schroeder et al. 2004). However, there are also numerous mechanisms by which livestock grazing might benefit sage-grouse (Beck and Mitchell 2000, Crawford...
The sagebrush rangelands of the Great Basin provide crucial habitat for a diversity of wildlife, including the pronghorn and the greater sage-grouse. These water-limited, highly-managed ecosystems have already been degraded by wildfires, the expansion of invasive grasses, and livestock grazing, and are expected to experience additional stress as climate and land use conditions change. Effective management of sagebrush ecosystems in the future will require the ability to understand and predict these future changes. To address this need, researchers will identify historical rates and causes of vegetation change in shrubland ecosystems, then use this information to develop potential future climate and land use scenarios...

FY2017Removal of livestock grazing is a common prescription to promote ecosystem recovery after wildfire (and subsequent emergency site rehabilitation efforts). Ecosystem recovery is typically considered from a terrestrial perspective, but wildfire and grazing can strongly influence aquatic ecosystems as well, especially smaller and fragmented stream networks, which are prevalent in the Great Basin (Minshall et al. 1989[1]; Dunham et al. 2003[2]; Luce et al. 2012[3]). Understanding these influences is essential for managing fire and grazing. Examples include identifying timeframes for resuming livestock grazing following wildfire, and the interactions between livestock grazing, fuels, and recovery of stream-side...
FY2014This projects main goals are to assess the effects of grazing by feral horses and livestock on Greater Sage-grouse demography and habitats. The Sheldon-Hart Mountain National Wildlife Refuge Complex and adjacent lands managed by the Bureau of Land Management provide the unique opportunity to assess sage-grouse populations free of feral horses and livestock grazing, populations that only have feral horses, as well as populations that coincide with both livestock grazing and feral horses. The project team will:1)Use historical sage-grouse data collected from Hart Mountain before and immediately after livestock were removed in the early 1990s, and historical data from Sheldon before the irruption of feral horses...

Land managers are responsible for developing effective strategies for conserving and restoring Great Basin ecosystems in the face of invasive species, conifer expansion, and altered fire regimes. A warming climate is magnifying the effects of these threats and adding urgency to implementation of management practices that will maintain or improve ecosystem functioning. This Factsheet Series was developed to provide land managers with brief summaries of the best available information on contemporary management issues to facilitate science delivery and foster effective management. Each peer-reviewed factsheet was developed as a collaborative effort among knowledgeable scientists and managers. The series begins with...

This presentation aired as part of the Great Basin LCC webinar series on September 13, 2017. Speakers include Courtney Conway, Idaho Cooperative Fish and Wildlife Research Unit, and Paul Makela, Bureau of Land Management.Description: Greater Sage-grouse have declined since the mid-1960s, and grazing is the most extensive land use within sage-grouse habitat. The speakers will present progress on a 10-year project designed to document the effects of cattle grazing on: 1) demographic traits of Greater Sage-grouse; 2) sage-grouse habitat characteristics, 3) insect abundance, which is important prey for sage-grouse chicks, and 4) abundance of all other bird species. The research team works at five study sites in Idaho...
Populations of Greater Sage-grouse have declined across the entire range of the species and habitat loss is considered to be the most important factor contributing to these declines (e.g., Connelly et al. 2004). Agricultural conversion, energy development, feral horses, and livestock grazing are hypothesized to contribute to habitat related threats (Range wide interagency sage grouse conservation team 2012). Substantial research has been completed to assess the effects of energy development (e.g., Walker et al. 2007) and agricultural conversion (e.g., Aldridge et al. 2008), yet, little research has been devoted to understanding the impacts of grazing by feral horses and livestock on sage-grouse demography.The Sheldon-Hart...

The data set consists of bird abundance data collected in undisturbed grassland fields enrolled in the Conservation Reserve Program (CRP) and former CRP fields that were converted to cropland, grazing land, or hayland in nine counties in four states (Montana, North Dakota, South Dakota, and Minnesota) in the northern Great Plains. The study was initiated in 1990, but data were only included in this dataset for the 18 years in which all three of the post-CRP management practices occurred, i.e., 1996–2003 and 2008–2017. The data were summarized and used in the analysis for a peer-reviewed publication entitled: "Conversion of CRP Grasslands to Cropland, Grazing Lands, or Hayland: Effects on Breeding Bird Abundances."...
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This spatial data set was created by the U.S. Geological Survey (USGS) to represent the extent of land in the Pacific Northwest region of the United States (Hydro Region 17; Major River Basin 7 (MRB7)) that potentially received waste from grazing cattle in 2002.
Seabeach amaranth (Amaranthus pumilus) is a plant species that was once prevalent on beaches of the U.S. mid-Atlantic coast but is now listed as threatened by the U.S. Fish and Wildlife Service. For much of the 20th century, seabeach amaranth was absent from the mid-Atlantic coast and thought to be extinct, presumably as a result of increased development and recreational pressure. One region where there has been an effort to restore the seabeach amaranth population is Assateague Island National Seashore (ASIS), a National Park Service land holding located along the coasts of Maryland and Virginia. Here, the Natural Resources staff at ASIS planted seabeach amaranth cultivars for three growing seasons from 1999...
These data were compiled to measure airborne horizontal mass flux of sediments moved by wind across soils, climates, vegetation types, and land uses on the Colorado Plateau. Objectives of our study were to quantify spatial and temporal patterns in wind erosion and further our understanding of how soil and site setting, climate, and land uses are controlling wind erosion and horizontal mass flux. These data represent seasonal cumulative horizontal mass flux as measured using passive aspirated sediment traps, Big Spring Number Eight (BSNE) samplers. These data were collected in Grand and San Juan counties, Utah, and Mesa County, Colorado, USA between August 2017 and November 2020. These data were collected by the...

This spatial data set was created by the U.S. Geological Survey (USGS) to represent the area of land within each incremental watershed delineated in the NHDPlus v2 dataset in the Pacific Northwest region of the United States (Hydro Region 17; Major River Basin 7 (MRB7)) that potentially received waste from grazing cattle in 2002.
The Invasion of native communities by cool-season introduced grasses, especially smooth brome and Kentucky bluegrass in upland prairies, reed canary grass in wetlands, is on one of the most important management issues on U.S. Fish and Wildlife Service (Service)-owned lands. Two adaptive management projects, the Native Prairie and Reed Canary Grass Adaptive Management Projects were funded by USGS to examine restoration efforts on NWRs and WMDs in USFWS Regions 3 and 6. This project will support the completion of two decision support tools that are essential to long-term resource management success.

Why Rangelands: The Central Valley of California, the surrounding foothills and the interior Coast Range include over 18 million acres of grassland. Most of this land is privately owned and managed for livestock production. Because grasslands are found in some of California’s fastest-growing counties, they are severely threatened by land conversion and development. In addition climate change stresses grasslands by potentially changing water availability and species distributions.Maintaining a ranching landscape can greatly support biodiversity conservation in the California Landscape Conservation Cooperative (LCC) region. In addition ranches generate multiple ecosystem services—defined as human benefits provided...
These data were compiled to support and inform the Bureau of Land Management’s Colorado Plateau Native Plant Program and to guide future management action when selecting regions to collect and increase seed for native plant materials development. The objective of our study was to develop geospatial datasets to aid land managers and restoration practitioners in identifying areas that will need to be restored in the future (currently disturbed) as well as areas to source new native plant materials for propagation with increased climate similarity to these areas across the Colorado Plateau, Arizona/New Mexico Mountains, and Arizona/New Mexico Plateaus. These data represent species distribution models for 12 high priority...
FY2016Develop and utilize both correlative and experimental approaches to evaluate effects of different intensities of spring cattle grazing on sage-grouse habitat selection, insect abundance, and sage-grouse demographic and behavioral traits. Collect data and document the effects of different levels of spring cattle grazing intensity on:1) sage-grouse demographic traits; 2) abundance and biomass of arthropods; 3) sage-grouse nest concealment and other vegetation/habitat features.Analyze the relationship between cattle grazing and sage-grouse demography at multiple spatial scales and evaluate the effects of experimental changes in cattle grazing on sage-grouse reproductive parameters.
