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...

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 effects of oil and gas development on the conservation of greater sage grouse (Centrocercus urophasianus) concerns wildlife managers. Effects of development are difficult to ascertain, a situation typical where cause-effect relationships are complex, multivariate, and involve landscape perspectives. Understanding the potential effects of development on grouse requires predicting where development is expected to occur on a landscape level. We gathered “reasonable foreseeable development” spatial data from the USDI’s Bureau of Land Management that were available for Montana, North Dakota, South Dakota, Wyoming, and Northwestern Colorado. These data were disparate across the study area, and we standardized them...

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...
The objectives of our research are to strengthen inference to sage-grouse population status and trend and provide biologists with support tools to implement sampling designs and population models. 1. Develop a statistical design to estimate the total number of greater sage-grouse leks at the 2. Determine sampling frequency and intensity required to meet precision and cost objectives at 3. Link sage-grouse population size estimates across time through the use of integrated 4. Develop a user-friendly, open-access software package in R that allows wildlife managers and biologists to design and analyze lek survey as well as fit Bayesian integrated population models. The software will link to LC-MAP to foster coordination...

A survey was developed to query sagebrush conservation practitioners to identify social networks, connections, and barriers. It was piloted with 13 advisory team members from state and federal agencies and NGOs, then distributed to a “master list” of 698 individuals identified through iterative polling efforts. The response rate for full surveys was 28%, quite good. The survey revealed 2015 network connections among 509 organizations and agencies working in sagebrush conservation. Work is ongoing to conduct a descriptive network analysis with whole network statistics and node level metrics and to develop the latent structure of the “dimensions of a learning organization” and modeling relationships between network...
Benefits to this proposal for the LCCs and FWS, sage-grouse researchers, and agencies responsible for managing and monitoring sage-grouse populations and habitat include: Leveraging economies of scale to facilitate mapping of sagebrush cover across a large landscape that would be impossible without the existing Grass/Shrub Mapping Project given the funds requested in this proposal. Exploitation of ongoing research and mapping science to meet the direct management need for a consistent sagebrush mapping product in which stakeholders of all interests can use as a base for their own applications. The combination of new technologies (Landsat 8 and WorldView-2 (WV2)) with partner funding contributions to increase...

We will use recently-developed models (see Hanser et al. 2011a) mapping the occurrence or abundance of six sagebrush obligate or near-obligate species of conservation concern (four songbirds, one reptile, and one mammal). We will evaluate how important habitats for each species overlap with similarly developed sage-grouse habitat occurrence models (Hanser et al. 2011b), as well as how sage-grouse priority habitats overlap with biodiversity hotspots for the other sagebrush species. This project will evaluate the degree to which sage-grouse conservation can act as an umbrella for other sagebrush dependent species within the Wyoming Basins ecoregion, the Utah-Wyoming-Rocky Mountain ecoregions in their entirety and...
Complete GIS conifer mapping across all parts of occupied sage grouse range impacted by encroachment (as identified in the Near-Term Conservation Plan). Availability of this data will eliminate an immense and long standing information gap that has hampered the broad scale planning necessary to address this threat. Recent outcome based studies completed by SGI and others are already available to facilitate easy assimilation of GIS mapping results by partners to promote associated conservation objectives identified in existing plans (e.g., Near-Term Plan, COT Report). Associated objectives include: • Target and accelerate removal of Phase I and II conifer encroachment in priority landscapes • Maintain or expand...

Trends in greater sage-grouse breeding populations are typically indexed by determining the peak number of males attending a lek in a lekking season. Numerous studies have estimated negative trends in sage-grouse breeding populations over time via data collected for the last 50 years. However, the inherent bias in data collection and unknown relationship between lek counts and population size limits the utility of using counts to evaluate range-wide population trends. This study estimated trends in the male segment of greater sage-grouse breeding populations within core and periphery areas in seven habitat management zones during two time periods, 1965-2015 and 2005-2015. In addition, we compared analysis methods...

PI’s and student have compiled and coded an extensive literature review of social science in the sagebrush biome. They have also developed, piloted and refined a social science needs assessment survey which has been transmitted to over 600 stakeholders in the sagebrush system (identified through Patrick Bixler’s work). They are now planning to conduct focus sessions in 4 states they are focusing on (WY, CO, ID, and OR), with the intent to focus a significant portion of the focus group discussion on the ways in which social science can inform decision making for sagebrush management and conservation.

This project expands upon a large, multi-agency collaborative study (Univ. of Idaho, Idaho Game and Fish, BLM, Great Basin LCC & two grazing Associations) evaluating the impacts of alternative grazing systems on sage-grouse over a 10-year period using a staggered entry BACI design. This project will evaluate the effects of grazing management prescriptions (intended to be compatible with greater sage-grouse) on other sagebrush-obligate or associated avian species. The results will contribute to an adaptive management process by: 1) assessing current state of populations of sagebrush-dependent birds as well as limiting factors, 2) compilation of models describing population-habitat relationships that can lead to species-habitat...

This project expands upon an already funded SGI initiative to optimize locations for conifer removal to benefit sage-grouse using the Falkowski conifer map layer (funded through LCMAP grant) and Doherty breeding density map. Adds capability to also optimize for sagebrush dependent songbirds (and potentially pygmy rabbits) while minimizing impacts to PJ obligates such as Pinyon Jays. Will import directly into dashboard decision support tool.

The proposed research is a collaboration of DOI (USGS, BLM, USFWS), USDA (PNW, USFS), and state agencies. State Heritage and other Nongame Programs have already shared their data with us in preparation for this study. This includes almost all 11 western states (some states did not record reptile occurrences). In exchange for this information, we will be providing to the states: (1) comprehensive species occurrence data with data record corrections; (2) maps of lizard and snake hotspots within each state; and (3) spatial models of species occupancy, including predicted changes in distribution under future climate scenarios. We will work with state (fish and game, state lands) and federal (BLM, USFWS, USFS) partners...

The proposal seeks to optimize conservation investments through three large-landscape level objectives: 1) Identify multi-species overlap of sagebrush migratory corridors to directly target conservation opportunities using cultivation risk assessment models. 2) Test if hoofed (i.e. pronghorn) and feathered (i.e. grassland birds, waterfowl) species can be managed under the Greater Sage-grouse umbrella. First, model seasonal range selection of pronghorn and then develop a multi-species decision support tool usingoverlaid seasonal range and migratory pathways to target management tools and conservation opportunities. 3) Test fencing effects on multi-species seasonal range and migratory pathways to target priority areas...

This project will develop a range-wide distribution map for pygmy rabbits through compilation and synthesis of existing presence-absence data and development of a predictive MaxEnt model. The proposed work would evaluate how well sage-grouse habitat conservation also supports landscapes inhabited by pygmy rabbits at both regional and range-wide scales, and this information can be used to inform integrated habitat conservation, restoration, and management that targets both of these sagebrush obligates. It is part of a larger intensive sage-grouse and pygmy rabbit distribution and habitat use study in Idaho supported by BLM, Forest Service and Idaho Department of Fish and Game.
