FY2014Although the future of sage grouse depends on the future of sagebrush, we have limited ability to anticipate impacts of climate change on sagebrush populations. Current efforts to forecast sagebrush habitat typically rely on species distribution models (SDMs), which suffer from a variety of well-known weaknesses. However, by integrating SDMs with complementary research approaches, such as historical data analysis and mechanistic models, we can provide increased confidence in projections of habitat change. Our goal is to forecast the effect of climate change on the distribution and abundance of big sagebrush in order to inform conservation planning, and sage grouse management in particular, across the Intermountain...

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 develop a strategic approach for conservation of wet meadows and riparian ecosystems and the species they support that focuses on threats caused by natural and anthropogenic disturbance. It uses information on (1) the factors that affect wet meadow and riparian ecosystem resilience to both natural and human-caused disturbances at the scale of the watershed and meadow or riparian ecosystem, and (2) the distributions and population abundances of at risk species to determine focal areas for management. Maps of the relative resilience of watersheds and wet meadows are overlaid with data on at risk species and the predominant threats to facilitate this process. Decision matrices are developed...

FY2013Cheatgrass die-offs are unexplained instances of stand failure observed in areas of Nevada and Utah, where cheatgrass fails to grow even though it has been a dominant component of plant communities in the past. The goals of this project are to:1) provide information on the size and extent of historic (1985 - 2012) die-offs in the Winnemucca area using satellite imagery, and 2) determine if die-offs are restoration opportunities by planting and monitoring local and commercially available native grasses in die-off areas.Support is requested to fund monitoring of the restoration project through a second growing season and to develop predictive spatial models of die-off from analysis of satellite imagery and GIS...

FY2013This project retrieves four years of data from over 200 temperature sensors nested within 28 sites across ~40 million hectares of the hydrographic Great Basin. The sensors span all major aspects and up to 700 m of elevation within sites, and occur in numerous management jurisdictions in 18 mountain ranges plus other areas not in ranges. This project: Quantifies the variability of climate at micro-, meso-, and macroscales across the Basin, and across diel, seasonal, and interannual periods. Informs management and conservation efforts, in terms of helping calibrate and refine the climatic stage upon which all biological actors and efforts hinge (Beier and Brost 2010). Feeds into other bioclimatic and wildlife...

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.

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....

FY2013The increase in large wildfires at a time when habitat for Greater Sage Grouse and other species dependent on big sagebrush has also increased has led to substantial needs for big sagebrush seeds. Significant decisions on which sagebrush seed to use and on management treatments that affect competing herb layers on the same restoration sites affect the trajectory of habitat.This project will evaluate how seed source, specifically genotype and climate-of-origin, interact with landscape-scale and replicated treatments (fencing, herbicide application, mowing, and seeding).

FY2010In addition to regional Science and Traditional Ecological Knowledge projects that the Great Basin LCC (GBLCC) supports, GBLCC staff lend technical expertise to a range of projects and have contributed to important regional publications on a range of subjects. These publications range in type from textbooks, to management-oriented science and conservation plans, to scientific papers and have covered subjects like wind erosion following fire, soil microbiota response to drought, plant community resilience to invasive species, and alpine plant communities. In many cases these publications form foundations for scientifically-informed management strategies across the Great Basin.

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...

FY2015This effort complements a project, supported by the Joint Fire Science Program, to explore relations among cheatgrass-driven fire, climate, and sensitive-status birds across the Great Basin. With support from the NW and SW Climate Science Centers and the GB CESU, we aim to engage managers at local, state, and regional levels, and to involve both field-level and director-level personnel, during all stages of the proposed project. Our methods of engagement are intended to save managers time and decrease some of the uncertainty in planning and decision-making rather than to create additional pressures on managers time. We will conduct field visits, workshops, and interactive briefings to build trust and increase...

FY2014The project team surveyed land managers working on invasive weeds in the west. These surveys provided information for the Western Association of Fish and Wildlife (WAFWA) Wildfire and Invasive Species Initiative Working Group. The survey results and other findings were used to inform a report titled Invasive Plant Management and Greater Sage-Grouse Conservation,published last spring.

FY2011Increasingly large wildfires in the Great Basin and Columbia Plateau have led to large dust storms in areas historically without them. Large dust storms have adversely affected human health, energy production operations, soil fertility, and mountain snowpack hydrology. USGS research efforts have investigated the causes and consequences of post-fire dust storms. Publications from this work are being used by managers with the Bureau of Land Management, Department of Energy, and other land managers to develop management practices that will minimize dust production.

FY2013Shrub-dominated ecosystems of the Great Basin are being threatened by disturbances, typically wildfire followed by encroachment of invasive plants (e.g., cheat grass). To mitigate these threats and future changes in the climate to big sagebrush (Artemisia tridentata), restorationists require a knowledge base and tools to inform them of the most appropriate seed sources to plant to greatly enhance the success of restoration under contemporary and future climates. We propose to develop climate-responsive seed transfer zones based on associating plant quantitative traits and ecophysiological data from common gardens to the climate of the seed source.

FY2011Thousands of data points have been collected by Oregon Department of Fish and Wildlife and Nevada Division of Wildlife from the 1950s to the present describing the distribution of declining native redband and endangered Lahontan cutthroat trout, and the invasive, nonnative brown and brook trout. USGS analyzed this data to understand the climate-related changes to species distributions and model extinction risk. The results, submittedfor publication, will be used by the State of Oregon as it drafts conservation plans for redband trout and by the Nevada Division of Environmental Protection in drafting water quality criteria to protect and monitor the states coldwater fisheries.

FY2016Review the existing literature, summarizing what is known about the scale and prevalence of local adaptation in the Great Basin and review current practices for determining seed transfer zones, describing benefits and limitations of different approaches. Through these two reviews, we will identify gaps in knowledge and opportunities for addressing these gaps, and determine best-practices for the construction of high quality seed transfer guidelines in a rapid and efficient manner. We propose to bring together a wide group of partners to achieve these goals, with two working group meetings proposed for this project. Deliverables include two peer-reviewed publications (existing knowledge, recommendation of best...

FY2014This project proposes to test the hypothesis that soil fungistasis (suppression of fungal pathogens by soil microbes in carbohydrate-limited soil) and its alleviation through natural carbohydrate augmentation (e.g., cheatgrass litter, leakage from cheatgrass roots) are the principal processes mediating patterns of cheatgrass die-off and recovery in die-off-prone areas.The project team will use laboratory, greenhouse, and field manipulative experiments to examine the effect of soil carbohydrates on cheatgrass disease incidence.
