A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Wildlife Biology Utah State University, Logan, Utah Abstract: "Declines in the distribution and abundance of greater sage-grouse ( Centrocercus urophasianus ; hereafter “sage - grouse” ) in western North America over the past century have been severe. The goal of my research was to increase the understanding of factors influencing where sage-grouse hens placed their nests, how common ravens ( Corvus corax : hereafter “raven” ) impacted sage-grouse nest success, and whether high raptor densities negatively impacted hen survival of sage-grouse. I compared raven and raptor densities at sage-grouse nest...

This theme is polygon data that depicts two types of development for the state of Wyoming. The first is existing development and the second are habitats where there is a high likelihood that development will occur in the near future. We considered development of oil, gas and coal bed methane, mining of minerals (trona, uranimum, coal, and bentonite), urban expansion. Other infrastructure activities such as roads, highways, fiberoptic lines, processing plants, pipelines, other facilities, and various combinations of development that were believed to impact sage-grouse were recorded. Information sources and assessment processes varied depending on data available and resource specialist participation for areas within...

Sage-grouse (Centrocercus spp.) were abundant in all of Utah's 29 counties at the time of European settlement wherever sagebrush (Artemisia spp.) occurred. Greater Sage-Grouse (G. urophasianus) inhabited areas north and west of the Colorado River, and Gunnison Sage-Grouse (G. minimus) occupied suitable habitat south and east of the Colorado River. The largest Greater Sage-Grouse populations in Utah are currently restricted to suitable habitats in Box Elder, Garfield, Rich, Uintah, and Wayne Counties. A remnant breeding population of Gunnison Sage-Grouse occurs in eastern San Juan County. We stratified Greater Sage-Grouse populations (1971-2000) by counties where the 1996 to 2000 moving average for estimated spring...
The Integrated Rangeland Fire Management Strategy (hereafter Strategy, DOI 2015) outlined the need for coordinated, science-based adaptive management to achieve long-term protection, conservation, and restoration of the sagebrush (Artemisia spp.) ecosystem. A key component of this management approach is the identification of knowledge gaps that limit implementation of effective strategies to meet current management challenges. The tasks and actions identified in the Strategy address several broad topics related to management of the sagebrush ecosystem. This science plan is organized around these topics and specifically focuses on fire, invasive plant species and their effects on altering fire regimes, restoration,...

This dataset contains landscape-scale greater sage-grouse Preliminary General Habitat. Specifically, it represents the remaining Sagebrush, Perennial grassland, Conifer encroachment, and some Persistence greater than 25% not accounted for in the 2012 Preliminary Priority Habitat dataset (Version 2 - April 2012). A combination of Key Habitat (Sather-Blair et al., 2000; ISAC 2006; BLM 2012), important winter and breeding habitat, local priority areas (spatially identified by the local working groups, BLM, IDFG biologists), known migration movement corridors, the revised 2011PA polygons, and exclusion of modeled agricultural and timber lands were used to further refine the 2012 Preliminary Priority Habitat (PPH) and...

Sage-grouse core areas are habitats associated with 1) Montana's highest densities of sage-grouse (25% quartile), based on male counts and/or 2) sage-grouse lek complexes and associated habitat important to sage-grouse distribution. The data are intended for display of sage grouse core areas in Montana. The data are intended for initial resource review and conservation planning. For evaluating or reviewing site specific applications Montana Fish, Wildlife & Parks (FWP) recommends contacting the appropriate FWP Regional office. These are the Montana SageGrouse Core Areas 2010 polygons for Idaho-SW Montana Greater Sage Grouse Subregion. Areas that overlap into Idaho do not apply to Idaho and may represent difference...
Emerging applications of ecosystem resilience and resistance concepts in sagebrush ecosystems allow managers to better predict and mitigate impacts of wildfire and invasive annual grasses. Soil temperature and moisture strongly influence the kind and amount of vegetation, and consequently, are closely tied to sagebrush ecosystem resilience and resistance (Chambers et al. 2014, 2016). Soil taxonomic temperature and moisture regimes can be used as indicators of resilience and resistance at landscape scales to depict environmental gradients in sagebrush ecosystems that range from cold/cool-moist sites to warm-dry sites. We aggregated soil survey spatial and tabular data to facilitate broad-scale analyses of resilience...

Sage-grouse habitat areas divided into proposed management categories within Nevada and California project study boundaries. HABITAT CATEGORY DETERMINATION The process for category determination was directed by the Nevada Sagebrush Ecosystem Technical team. Sage-grouse habitat was determined from a statewide resource selection function model and first categorized into 4 classes: high, moderate, low, and non-habitat. The standard deviations (SD) from a normal distribution of RSF values created from a set of validation points (10% of the entire telemetry dataset) were used to categorize habitat ‘quality’ classes. 1) High quality habitat comprised pixels with RSF values < 0.5 SD. 2) Moderate > 0.5 and < 1.0 SD. 3)...

This data set represents SAGE GROUSE (Greater sage-grouse and Gunnison sage-grouse) brooding use areas in Utah as determined by UDWR field biologists in spring 1999. In May 2006 the dataset was converted from a Critical, High, Substantial and Limited value system to a Crucial/Substantial value system.
The review provides an overview of the features of the North Sea and the Baltic Sea in their European geographical and socio-political context. To reach sustainability in the wider sense the common society has to meet the 7 tenets - that management actions have to be environmentally sustainable, economically viable, technologically feasible, socially desirable (or at least tolerable), legally permissible, administratively achievable and politically expedient. Each of these are explained and discussed using examples from the two seas including pollution control, physical resource exploitation (such as aggregates, habitat loss, renewable energy and oil and gas), and biological resources exploitation (fisheries and...

These connectivity areas correspond to the Version 3 core areas in Wyoming. They are closely linked to the core areas but are NOT core.
This webinar was recorded on May 7, 2015. Sustainable management of natural resources under competing demands is challenging, particularly when faced with novel and uncertain future climatic conditions. Meeting this challenge requires the consideration of information about the effects of management, disturbance, land use, and climate change on ecosystems. State-and-transition simulation models (STSMs) provide a flexible framework for integrating landscape processes and comparing alternative management scenarios, but incorporating climate change is an active area of research. In this presentation, three researchers present work funded by Climate Science Centers across the country to incorporate climate projections...

State policies can support renewable energy development by driving markets, providing certainty in the investment market, and incorporating the external benefits of the technologies into cost/benefit calculations. Using statistical analyses and policy design best practices, this paper quantifies the impact of state-level policies on renewable energy development in order to better understand the role of policy on development and inform policy makers on the policy mechanisms that provide maximum benefit. The results include the identification of connections between state policies and renewable energy development, as well as a discussion placing state policy efforts in context with other factors that influence the...

These data represent predicted common raven (Corvus corax) density (ravens/square-km) derived from random forest models given field site unit-specific estimates of raven density that were obtained from hierarchical distance sampling models at 43 field site units within the Great Basin region, USA. Fifteen landscape-level predictors summarizing climate, vegetation, topography and anthropogenic footprint were used to predict average raven density at each unit. A raven density of greater than or equal to 0.40 ravens/square-km corresponds to below-average survival rates of sage-grouse (Centrocercus urophasianus) nests. We mapped areas which exceed this threshold within sage-grouse concentration areas to determine where...
