a. Develop a regional map showing the highest probability pathways of wildfire spread under current conditions.b. Design regional networks of fuel breaks to reduce future wildfire size in large remnant tracts of priority GSG habitat. Networks will be designed by modeling fire spread with fuel breaks using Circuitscape (http://www.Circuitscape.org/), a wildlife connectivity software based on electrical circuit theory applied to a raster map, and consulting with agencies and tribes about regional priority habitats in southern ID and OR, northern NV,and northwestern UT.c. Deliver GIS layers and maps showing suggested networks of fuel breaks to federal and state agencies, and tribes. This will allow fire managers to...

Covering 120 million acres across 14 western states and 3 Canadian provinces, sagebrush provides critical habitat for species such as pronghorn, mule deer, and sage-grouse – a species of conservation concern. The future of these and other species is closely tied to the future of sagebrush. Yet this important ecosystem has already been affected by fire, invasive species, land use conversion, and now, climate change. In the western U.S., temperatures are rising and precipitation patterns are changing. However, there is currently a limited ability to anticipate the impacts of climate change on sagebrush. Current methods suffer from a range of weakness that limits the reliability of results. In fact, the current uncertainty...

We propose to evaluate reproductive vital rates of sagebrush songbirds in relation to key aspects of local climate. To accomplish this we will leverage several large existing datasets of nesting observations from over six thousand nests across multiple years and sites, archived weather station data (temperature, precipitation, and relative humidity), and gridded climate datasets (e.g., PRISM). To further examine whether particular landscapes and/or microhabitats may confer more protection in the face of increasingly more extreme weather events (e.g., high temperatures and drought) expected with climate change, we will incorporate habitat data collected remotely and at nests into climatic response models. Finally,...

The overall objective of this work is to understand how changing climate and associated ecohydrological conditions will impact the distribution of sagebrush ecosystems over the next century. This study will provide valuable insight into the vulnerability of sagebrush ecosystems to changes in climate, climate variability, and disturbance regime. This work utilizes the best currently available downscaled climate data (Maurer) and builds upon recent published results. Products from this project will provide wildlife managers with the ability to categorize and prioritize areas based on their probability of being capable of supporting sagebrush ecosystems in the future, information that is crucial for upcoming listing...

In partnership with WAFWA MDWG and many participating western states, we propose the following three-pronged plan:1) Develop a standalone program which simplifies the technologically challenging analyses outlined in Sawyer et al. (2009b) into a user-friendly software add-on that can be implemented by biologists and managers using their own GPS collar data. 2) Work with biologists and managers of state agencies to analyze mule deer data sets. Specifically, using the program outlined in objective 1, we will assess the broad applicability of the analysis methods to identify migration corridors. This step will include the development of a list of key issues and considerations for analyzing these types of data in addition...
