What are current conditions for important park natural resources? What are the critical data and knowledge gaps? What are some of the factors that are influencing park resource conditions? Natural Resource Condition Assessments (NRCAs) evaluate and report on the above for a subset of important natural resources in national park units (hereafter, parks). Focal study resources and indicators are selected on a park-by-park basis, guided by use of structured resource assessment and reporting frameworks. Considerations include park resource setting and enabling legislation (what are this park's most important natural resources?) and presently available data and expertise (what can be evaluated at this time?). In addition...

This database contains literature citations and associated summaries pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on the Oregon spotted frog (Rana pretiosa) and other listed/sensitive wetland-breeding amphibians in the western United States. This is not meant to be an exhaustive list, nor did we perform a systematic meta-analysis; rather, literature records were included based on topical relevance. *HINT: If you are looking for the database SEARCH TOOL, scroll down to 'Attached Files' and download 'Annotated_bibliography_with_search_tool.accdb.'

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...

This data represents grazing allotment boundaries managed by the BLM. Allotments are permitted use areas for public grazing of cattle, sheep and horses. Allotments can be a mixture of different surface ownerships, for example a BLM allotment can encompass privately owned land or state land Allotments can also be leased to various types of livestock, cattle, sheep and/or horses.

Web Soil Survey (WSS) provides soil data and information produced by the National Cooperative Soil Survey. It is operated by the USDA Natural Resources Conservation Service (NRCS) and provides access to the largest natural resource information system in the world. NRCS has soil maps and data available online for more than 95 percent of the nation’s counties and anticipates having 100 percent in the near future. The site is updated and maintained online as the single authoritative source of soil survey information. Soil surveys can be used for general farm, local, and wider area planning. Onsite investigation is needed in some cases, such as soil quality assessments and certain conservation and engineering applications....

This is a spatially-explicit state-and-transition simulation model of rangeland vegetation dynamics in southwest South Dakota. It was co-designed with resource management partners to support scenario planning for climate change adaptation. The study site encompasses part of multiple jurisdictions, including Badlands National Park, Buffalo Gap National Grasslands, and Pine Ridge Indian Reservation. The model represents key vegetation types, grazing, exotic plants, fire, and the effects of climate and management on rangeland productivity and composition (i.e., distribution of ecological community phases). See Miller et al. (2017) for further details. The model was built using the ST-Sim software platform (www.apexrms.com/stsm)....

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 data set contains output from the dynamic vegetation model MC1, as modified to simulate future woody encroachment in the northern Great Plains, for 23 monthly variables, 63 yearly variables, and 31 multi-year variables. Variables include simulated plant (by growth form) and soil carbon stocks, net primary production, vegetation type, potential and actual evapotranspiration, stream flow, and fuel mass and moisture. Model output is provided for the EQ, Spinup, Historical, and Future stages of MC1 runs; future stages were run for four climate projections crossed with 10 or 11 fire X grazing X CO2 concentration scenarios for the western and eastern portions of the study area, respectively.

Data included in this data set are from edge-of-field surveys that recorded the presence of erosional features, cover of vegetation and bare ground, and management activities (e.g., haying) on 1092 fields that had expired from three types of conservation practices (grassland, wetland, and wildlife) in the Conservation Reserve Program. 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 2017 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....

This data set is digital grazing allotments for the Casper Field Office. The information was prepared by digitizing the grazing allotment boundaries for the 4 counties-Natrona, Converse, Platte and Goshen. The pasture boundaries were digitized for the area within Natrona county. The data in Natrona county was digitized by the Wyoming State Office using data from mylars prepared by the field office and using 7.5 minute USGS Quadrangle maps as a base. The other 3 counties were digitized on screen using the USGS Quandrangle maps and the ownership maps as a backdrop. The data was completed by county and then merged into one coverage.
This data set contains output from the dynamic vegetation model MC1, as modified to simulate future woody encroachment in the northern Great Plains. Simulations were done for the historical period (1895-2005) and the future period (2006-2100). Separate simulations were done for eastern and western portions of the region, with the eastern simulations using model parameters appropriate for Juniperus virginiana as the major evergreen needle-leaf life form, and the western simulations using model parameters appropriate for Pinus ponderosa as the major evergreen needle-leaf life form. Simulations in each portion were run for two A2 emissions scenario climate projections (CSIRO, representing moderate temperature increases...
