This project will support the use of the Breeding Bird Survey (BBS) data to calculate current populations, population trend, and ultimately desired population objectives for the priority species outlined in the IR 5/7 SHC Plan. Benchmarks will be estimated to highlight grassland and sagebrush habitat needed to support desired populations as outlined in the Partners in Flight Plan by 2050. The BCR specific population targets provide a solid foundation to continue to build and refine the R6 SHC Teams Work towards effective planning and ultimately effective on-the-ground conservation delivery. A $55,000 investment supports conservation priorities for both Grassland and Sagebrush Ecosystems.

Land use was quantified within a 4-km radius around 36 apiaries in North Dakota, South Dakota, and Minnesota over two years, 2015-16 and 2016-17. The area (hectares) of Ag (corn, soy, small grains), Grass (pasture, grassland, fallow land, wildflowers, shrub land, and hay land), Wetlands (herbaceous and woody), and Bee crops (alfalfa, canola, sunflower) were quantified around each apiary in each year. Within each apiary, the average change in frames of adult bees among all colonies from June to September was calculated. Additionally, the average September Varroa mite infestation rate, the average adult population size during almond pollination, the count of colonies exhibiting queen events in September, and the count...
Plant invasions have the potential to significantly alter soil microbial communities, given their often considerable aboveground effects. We examined how plant invasions altered the arbuscular mycorrhizal fungi of native plant roots in a grassland site in California and one in Utah. In the California site, we used experimentally created plant communities composed of exotic (Avena barbata, Bromus hordeaceus) and native (Nassella pulchra, Lupinus bicolor) monocultures and mixtures. In the Utah semi-arid grassland, we took advantage of invasion by Bromus tectorum into long-term plots dominated by either of two native grasses, Hilaria jamesii or Stipa hymenoides. Arbuscular mycorrhizal fungi colonizing roots were characterized...

These data represent 2 years of plant clipping data in areas with elk plus bison and areas of elk only in the San Luis Valley of Colorado, USA from 2006-2008. Clipping plots were measured (clipped) in meadow sites, herbaceous riparian sites, and willow communities. We clipped 1/4 m2 (meter-squared) rings inside and outside of 1-m2 grazing cages, as well as within large ungulate exclosures that were 0.04 ha (hectares) in size.

RaBET (Rangeland Brush Estimation Toolbox for Major Land Resource Areas (MLRAs)) is an online ArcGIS toolbox that generates accurate geospatial and tabular data describing canopy cover at the tract level to streamline landowner agreements (USFWS Partners for Fish and Wildlife PFW) and/or NRCS Environmental Quality Incentives Program (EQIP) contracts for brush management. Priority MLRAs cover 33.8 million acres with 20.6 million acres of grasslands. This project supports the integration of RaBET into project planning and contract development and is projected to increase the number of contracts and acres impacted by 25% (23,750 acres) in these MLRAs in Kansas and Nebraska through NRCS EQIP alone, based on 2020 enrollment....

This project will develop demographic and population data from existing databases, including state creel surveys, annual sampling efforts, and state Natural Heritage programs for a suite of species (aquatic, terrestrial, pollinator) that inhabit the sagebrush-steppe and grassland ecosystem. Collecting this information is a vital first step toward understanding these species response to climate change, including changes in water quality/quantity, flooding recurrence, and persistence of instream and riparian habitats in sagebrush and grassland systems over time. Support for this foundational work will enable the FWSIR5/7 Sagebrush Ecosystem Team to develop population models and associated threat-based models to inform...

Grassland birds have declined more rapidly than any other group of land birds in North America in the last 50 years, with populations of Spragues Pipit, Chestnut-collared and Thick-billed Longspur, and Bairds Sparrow having declined 65-94% during this period. Developing strategic conservation plans for grassland birds requires an understanding of their individual population ecology, along with their community dynamics amongst species. Few studies have focused on understanding how adult density during the breeding season relates to nesting performance (e.g., nest density and nest success) and how abiotic and biotic factors influence these individual demographics. This proposed work complements concurrent studies...

The range-wide plan (RWP) has been developed in response to concerns about lesser prairie-chicken (LPC) habitat threats which may be impacting LPC populations, and the proposed listing under the Endangered Species Act (ESA). Along with the existing conservation efforts already being implemented, as described in the RWP, the supporting WAFWA Conservation Agreement (WCA) represents another mechanism to implement conservation to benefit LPC. The WCP represents an opportunity to enroll participants who agree to avoid, minimize and mitigate actions which may be detrimental to LPC. Landowners may enroll properties to be managed for the benefit of LPC. Properties may generate credits for mitigation. When complete avoidance...
We investigated the influence of long-term (56 years) grazing on organic and inorganic carbon (C) and nitrogen (N) contents of the plant-soil system (to 90 cm depth) in shortgrass steppe of northeastern Colorado. Grazing treatments included continuous season-long (May-October) grazing by yearling heifers at heavy (60-75% utilization) and light (20-35% utilization) stocking rates, and nongrazed exclosures. The heavy stocking rate resulted in a plant community that was dominated (75% of biomass production) by the C4 grass blue grama (Bouteloua gracilis), whereas excluding livestock grazing increased the production of C3 grasses and prickly pear cactus (Opuntia polycantha). Soil organic C (SOC) and organic N were not...

This spatial data set provides information pertaining to the known land use and disturbance history for lands within the March 2018 administrative boundary of (Park, state). Land use and disturbance history presented here are not a comprehensive record of all potential land uses and disturbances but rather a record of known and documented land uses and disturbances based on the best available information. Additional land use and disturbance information may exist but due to time and budget constraints may not have been discovered during the research and development of this data set. The information in this data set was gathered through a variety of sources including but not limited to communication with National...

As part of a 2018 Northwest Climate Adaptation and Science Center project, USGS researchers are releasing a series of spatially-explicit land-cover projections for the period 2018-2050 covering part of the northern Great Basin (Beaty Butte Herd Management Area, Hart Mountain National Antelope Refuge, and Sheldon National Refuge). The dataset contains an empirically-based business-as-usual (BAU) and an RCP8.5 climate change scenario executed for shrub, herbaceous, and bare cover types. Each scenario is executed 30 times (i.e. Monte Carlo simulations) to account for variability across historical change estimates derived from annual fractional cover maps generated by the National Land Cover Database. The map dates...

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...

In response to concerns about rangeland fragmentation associated with exurban development, ranching families, agency representatives, and conservation groups have organized to address management concerns through the Malpai Borderlands Group (see: http://www.malpaiborderlandsgroup.org). This group promotes large acreage conservation easements throughout the region as means to promote rangeland connectivity. Shrub encroachment and long-term loss of grass productivity are primary natural resource concerns. Fire, which is facilitated in areas free of exurban development, is a key conservation practice. Additional practices include mechanical brush management, prescribed grazing, and erosion control structures. The conservation...
