FY2013The proposed project’s objective is to provide a scientific review of(1) current priority species management practices in Nevada, (2) status of our combined scientific knowledge of priority species’ needs and gaps in that knowledge, and(3) adequacy of current monitoring programs of priority species.The project builds on recent, well-researched species conservation plans for Nevada (GBBO 2010, NWPT 2012), and it will leverage funds that are already obligated to research on scientifically based disturbance buffer recommendations and to evaluate GBBO’s statewide landbird monitoring program, the Nevada Bird Count.The outcome of the proposed work will be an online open-source compendium document that summarizes...
FY2015Collaborators are investigating the effect of low rise dams water supply, ecosystem functions and health, and habitat for a wide range of organisms, including sage grouse. They are assessing the economic cost and attitudes of ranchers and managers towards both low-rise dams and proposed re-introductions of beavers. Remote sensing is used to identify locations of incised streams across the Great Basin.
FY2017Increasing effectiveness of post-fire treatments is a management priority, such as is emphasized in Secretarial Order #3336 on rangeland fire and restoration, which prescribes a programmatic, longer-term approach that accommodates the layering of different treatments in sagebrush-steppe rangelands. The phasing of treatments by applying them in different post-fire years is an important part of wildfire response that, along with timing of livestock grazing resumption, likely affects overall project success - but is yet under studied. This projects objective is to determine the incremental gains in increasing desirable perennials and decreasing exotic annual grasses with the phasing of land management actions...
FY2016This project will evaluate the effects of vegetation treatments on population connectivity, genetic diversity and gene flow of wildlife species across the full extent of the Great Basin LCC. The recently approved BLM and Forest Service Land Use Plan Amendments will implement millions of acres of treatments in support of greater sage-grouse conservation. It is essential to evaluate the potential benefits and risks of these treatments on the connectivity and fragmentation of the landscape for multiple non-target species. We will use a dynamic landscape model to simulate fire and treatments, allowing each to vary by type (e.g., juniper removal, prescribed fire), extent, and influence on vegetation and fuels....

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...
FY2014Land management agencies seek to understand how organisms use the landscape in order to develop management strategies that maintain healthy, resilient communities that have the ecological and evolutionary potential to respond to climate change. An ideal approach to understanding how organisms move through the landscape is by inferring ongoing and historic movements from patterns of genetic continuity that characterize regional sets of populations. From patterns of genetic connectivity we can infer the habitat and landscape characteristics that facilitate animal movement and species range shifts over both short and long timescales. Knowing the spatial distribution of critical linkages or corridors allows conservation...
FY2015The Great Basin Region, which covers much of Nevada, and portions of California, Oregon, Idaho, and Utah, managers are already confronting a changing climate and are beginning to make management decisions despite uncertainty in how climate change effects will manifest in the region. To support decision making, the Great Basin Landscape Conservation Cooperative (LCC) and the National Oceanic and Atmospheric Administration (NOAA) Regional Integrated Science Assessment Program (RISA) funded this project to explore how two scenario planning approaches might be used effectively with existing management planning processes and data sources and how to begin prioritizing adaptation strategies. The two approaches used...

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.

FY2017This study addresses the need to develop treatments, soil amendments, and other site-preparation techniques that enhance germination, establishment, and development of healthy sagebrush communities. This study addressed the following objectives: (1) Determine whether seeded sagebrush established more frequently in fertile islands compared to burned shrub interspaces and locations where sagebrush was absent prior to the fire; (2) Determine whether the soil characteristics of sites and fertile islands within those sites influence sagebrush establishment patterns; and (3) Consider whether fertile island soil characteristics could be reporduced by manipulation post-fire soils in areas that had no pre-fire sagebrush....
FY2017The Integrated Rangeland Fire Management Strategy Actionable Science Plan places a high priority on assessing control measures for invasive annual grasses, which provide fuel for rangeland fire and impede restoration of desirable perennials. Weed-suppressive strains of the bacterium Psuedomonas fluoresens (P.f.) are an emerging but yet untested tool for selectively reducing these annual grasses. P.f. may suppress annuals for approximately 2-5 years, bridging the short-term action of herbicides and long-term resistance provided as native bunchgrasses recover. In 2015-2016, the USGS responded to a request from the Idaho sage grouse action group to establish a series of field-based experiments to assess the efficacy...
FY2014Avoiding cheatgrass dominance following tree-reduction treatments on woodland-encroached sagebrush communities is a priority for managers in the Great Basin. Perennial herbaceous and weedy annual cover have been related to site resilience after treatment and associated with soil climate regimes and site physical characteristics. Additional investigation of site characteristics associated with vegetation response will allow us to better decide which sites to treat and whether seeding is needed or not in conjunction with tree reduction treatments. Site-level planning also requires an understanding of how climate change may influence vegetation response to treatments.We propose to associate site-measured soil...
