This is a spatially-explicit state-and-transition simulation model (STSM) of sagebrush-steppe vegetation dynamics for greater sage-grouse (Centrocercus urophasianus) Priority Areas for Conservation (PACs) in the Great Basin. The STSM was built using the ST-Sim platform and uses an integrated stock-flow submodel (STSM-SF) to simulate and track continuous vegetation component cover changes caused by annual growth, natural regeneration, and post-fire sagebrush seeding and planting restoration. Spatially explicit models were built for three sage-grouse PACs (Klamath Oregon/California [KLAM], NW Interior Nevada [NWINV], Strawberry Utah [STRAW]) that differed in historic wildfire patterns and the amounts of various component...
Potential future greater sage-grouse (Centrocercus urophasianus) habitat restoration was projected (2018-2068) for three sage-grouse Priority Area for Conservation (PACs) populations located along the northwestern, central, and eastern edge of the Great Basin using outputs from a spatially explicit state-transition simulation model (STSM) developed for sagebrush ecosystems. These datasets, for the NW-Interior Nevada, USA (NWINV) sage-grouse population, include: 1) a set of 78 categorical raster layers illustrating a time series (decade intervals) of potential future habitat, and 2) a set of 15 uncategorized raster layers illustrating potential change in habitat classification across space, after simulating 50 years...
Escalated wildfire activity within the western U.S. has widespread societal impacts and long-term consequences for the imperiled sagebrush (Artemisia spp.) biome. Shifts from historical fire regimes and the interplay between frequent disturbance and invasive annual grasses may initiate permanent state transitions as wildfire frequency outpaces sagebrush communities’ innate capacity to recover. Therefore, wildfire management is at the core of conservation plans for sagebrush ecosystems, especially critical habitat for species of conservation concern such as the greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse). Fuel breaks help facilitate wildfire suppression by modifying behavior through fuels...

This project will apply the results of an on-going climate change vulnerability assessment to the management of two complex landscapes. The vulnerability assessment project team will work with mangers, land-owners, and conservation practitioners to explore 1) how downscaled climate datasets, modeled vegetation changes, and information on estimated species sensitivities can be used to develop climate change adaptation strategies, and 2) how model results and datasets can be made more useful for informing the management of species and landscapes. To accomplish these two goals, we will prepare datasets and model outputs for two landscapespotentially, the Pioneer Mountains-Craters of the Moon region in Idaho and the...

Greater sage-grouse (Centrocercus urophasianus) is a candidate for listing under the Endangered Species Act because of population and habitat fragmentation coupled with inadequate regulatory mechanisms to control development in critical areas. In addition to the current threats to habitat, each 1 degree celsius increase due to climate change is expected to result in an additional 87,000 km2 of sagebrush (Artemisia spp.) that will be converted to unsuitable habitat for sage-grouse. Thus, the future distribution and composition of sagebrush landscapes is likely to differ greatly from today’s configuration. We conducted a large, multi-objective project to identify: (1) characteristics of habitats required by sage-grouse,...

Greater sage-grouse genetic connectivity is essential to the species persistence across the Great Northern landscape; without such connectivity the greater sage-grouse may suffer the same fate as many other related species of grouse, which disappeared from the middle and eastern portion of the United States due to loss of habitat coupled with inbreeding depression. To prevent isolation in the face of energy development and other landscape changes it is essential that we evaluate both fine-scale connectivity and assign relative importance to different leks (breeding populations) on the landscape. This massive task cannot be accomplished with existing tools and maps; fortunately, advanced molecular genomic analyses...

Managers require quantitative yet tractable tools that can identify areas for restoration yielding effective benefits for targeted wildlife species and the ecosystems they inhabit. A spatially explicit conservation planning tool that guides effective sagebrush restoration for sage-grouse can be made more effective by integrating baseline maps describing existing (pre-restoration) habitat suitability, and the distribution and abundance of breeding sage-grouse. Accordingly, we provide two rasters. The first is a floating point raster file informed by lek data, and derived from: 1) utilization distributions weighted by lek attendance, and 2) a non-linear probability of space-use relative to distance to lek. The second...
Habitat similarity index (HSI) values for greater sage-grouse across their western range. HSI values represent the relationship of environmental values at map locations to the multivariate model of minimum requirements for sage-grouse defined by land cover, anthropogenic variables, soil, topography, and climate.
This study addressed the challenges faced by natural resource management planning in the context of climate change. We explored how future climate may interact with management alternatives to shape wildlife habitat across large landscapes. We studied habitat for the northern spotted owl in coastal Washington and southwestern Oregon, and habitat for the greater sage-grouse in southeastern Oregon. In coastal Washington, the primary threat to owl habitat is likely to be habitat loss as a result of increasing fire and shifts in vegetation with changing climate. These threats may not be fully mitigated with management. In southwest Oregon, increasing fire frequencies under climate change are also likely to pose the greatest...
Wildfires are increasingly modifying wildlife habitat in the western United States and managers need ways to scope the pace and degree to which post-fire restoration actions can re-create habitat in dynamic landscapes. We simulated post-fire revegetation and greater sage-grouse (Centrocercus urophasianus) habitat restoration using a spatially explicit state-transition simulation model (STSM) developed for sagebrush ecosystems. The STSM represented the vegetation dynamics of the sagebrush ecosystem and included annual fires, annual grass invasion, conifer encroachment, and sagebrush revegetation restoration. We compared simulated vegetation output with sage-grouse perennial grass and sagebrush cover habitat needs...
The Washington Connected Landscapes Project will provide a framework to address the interacting impacts of habitat fragmentation and climate change on ecological systems and wildlife species within the Great Northern Landscape Conservation Cooperative (GNLCC) boundary.Managing for well-connected landscapes is a key strategy to enhance resilience and ensure the long-term viability of plant and animal populations. However, conservation planning efforts have rarely included connectivity for ecological processes such as dispersal, migration, and gene flow. Connectivity conservation is particularly important in the face of climate change, because many species will require highly permeable, well-connected landscapes not...

This project will integrate the shared priorities developed by the Arid Lands Initiative (ALI) in the Columbia Plateau ecoregion into implementation mechanisms of existing and new ALI partners. The project will finalize the ALIs comprehensive strategy by assessing and agreeing on which partners are best positioned to implement which priority actions in which priority areas, integrate these priorities into existing partner work, identify gaps that new partners need to be engaged to address, design 1-2 ALI projects for collaborative implementation, and track and adapt the overall implementation efforts. This project will not only allow the ALI to successfully transition from planning to coordinated action, but will...

This report provides a strategic approach developed by a Western Association of Fish and Wildlife Agencies interagency working group for conservation of sagebrush ecosystems, Greater sage-grouse, and Gunnison sage-grouse. It uses information on (1) factors that influence sagebrush ecosystem resilience to disturbance and resistance to nonnative invasive annual grasses and (2) distribution and relative abundance of sage-grouse populations to address persistent ecosystem threats, such as invasive annual grasses and wildfire, and land use and development threats, such as oil and gas development and cropland conversion, to develop effective management strategies. A sage-grouse habitat matrix links relative resilience...

Successful adaptive management hinges largely upon integrating new and improved sources of information as they become available. Updating management tools for greater sage-grouse (Centrocercus urophasianus, hereafter referred to as “sage-grouse”) populations, which are indicators for the large-scale health of sagebrush (Artemisia spp.) ecosystems in the Great Basin of North America, provide a timely example for this tenet. Recently developed spatially-explicit habitat maps derived from empirical data played a key role in the conservation of this species facing listing under the Endangered Species Act. Herein, this report provides an updated process for mapping relative habitat suitability and management categories...

We developed rangewide population and habitat models for Greater Sage-Grouse (Centrocercus urophasianus) that account for regional variation in habitat selection and relative densities of birds for use in conservation planning and risk assessments. We developed a probabilistic model of occupied breeding habitat by statistically linking habitat characteristics within 4 miles of an occupied lek using a nonlinear machine learning technique (Random Forests). Habitat characteristics used were quantified in GIS and represent standard abiotic and biotic variables related to sage-grouse biology. Statistical model fit was high (mean correctly classified = 82.0%, range = 75.4–88.0%) as were cross-validation statistics (mean...

Our 2010 statewide connectivity analysis identified broad-scale priority areas for connectivity conservation. More detailed, finer-scale analyses will give land managers the information they need to begin prioritizing and implementing conservation actions. The Columbia Plateau (Appendix A, Fig. 1) was selected for the first ecoregional-scale analysis for two reasons. First, several climate models suggest that the Columbia Plateau Ecoregion in Washington is likely to be a stronghold of shrubsteppe ecosystems under climate change. Second, despite the high level of habitat loss and fragmentation in the ecoregion, our statewide analysis identified previously undocumented patterns and opportunities for multiple-species...

These protocols are intended to identify key questions to be addressed, preferred approaches to addressing these questions, and issues likely to be encountered by scientists studying impacts of wind energy development on sage-grouse. I discuss advantages and disadvantages of possible study designs. A full BACI (Before After Control Impact) design with five years of preconstruction data and at least five years of post-construction data that estimates fundamental demographic parameters and habitat selection over a distance gradient from wind facilities provides the strongest design. Research proposals considered for funding by the GS3C-Sage-Grouse Collaborative will be evaluated based on their abilities to adhere...
We developed a hierarchical clustering approach that identifies biologically relevant landscape units that can 1) be used as a long-term population monitoring framework, 2) be repeated across the Greater sage-grouse range, 3) be used to track the outcomes of local and regional populations by comparing population changes across scales, and 4) be used to inform where to best spatially target studies that identify the processes and mechanisms causing population trends to change among spatial scales. The spatial variability in the amount and quality of habitat resources can affect local population success and result in different population growth rates among smaller clusters. Equally so, the spatial structure and ecological...
