BLM REA NGB 2011 Pronghorn Habitat (California)

This is a Northeast California layer showing pronghorn kidding grounds, migration corridors, stress migration corridors, and winter range. These areas were designated by DFG biologists based upon their personal knowledge of these ranges. The purpose of this dataset is to provide locational information regarding Pronghorn range throughout Northern California. The locations of these features are based on the best-professional judgment of DFG Biologists and have not been rigorously examined by current technical means (e.g., telemetry, GPS radio collars, etc). These data were compiled by DFG Unit Biologists in the 1970s under what was then known as the Areas of Significant Biological Importance (ASBI) project performed...

Randomized shortest paths for Grizzly Bear dispersal between the GYE and NCDE

The Randomized Shortest Path (RSP) raster delineates potential dispersal paths for male-mediated gene flow between grizzly bear (Ursus arctos) populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE). A RSP algorithm was used to estimate the average number of net passages for all grid cells at a spatial resolution of 300 m in the study region which spans parts of Montana, Idaho, and Wyoming. RSP rasters identify potential movement paths for 3 levels of random deviation determined by the parameter Θ (i.e., Θ = 0.01, 0.001, and 0.0001) for bears moving from an origin to a destination node. Lower values of Θ result in greater exploration and more random deviation around...

Journal Article: Genetically distinct populations of the pygmy rabbit (Brachylagus idahoensis) in the Mono Basin of California

We examined patterns of genetic variation and diversity of extant pygmy rabbit (Brachylagus idahoensis) populations across the species’ current range in Nevada and California. Our aims were to determine population genetic structure and levels of diversity across the southern portion of the species’ range. We genotyped 13 microsatellite loci from 194 fecal samples collected across 14 localities. Our Bayesian cluster analyses found 2 genetically distinct groups: 1 in the Mono Basin of California and the other encompassing all remaining Nevada Great Basin populations. Considering only the Nevada Great Basin group, we found 4 minimally divergent groups that overlap spatially with many individuals maintaining composite...

North Pacific Forest Landscape Corridor and Connectivity Project: Assessing Landscape and Species Vulnerability - Spatial Data

Montane Conifer Connectivity of areas of high elevation and high human footprint in the North Pacific Landscape Conservation Cooperative study area. This application provides Montane Conifer Connectivity for 2000 and 2080 (A1B).The three primary geospatial layers used in this analysis were a digital elevation model (DEM), a vegetation layer, and a human footprint layer. Due to the geographic extent of the North Pacific Landscape Conservation Cooperative, digital elevation models from different sources had to be used to create one seamless DEM. The digital elevation models were obtained from the Shuttle Radar Topography Mission (SRTM), the United States Geologic Survey, and the Government of the Yukon Territory....

North Pacific Forest Landscape Corridor and Connectivity Project: Assessing Landscape and Species Vulnerability - Final Report

Overview Land and resource managers in the North Pacific Landscape Conservation Cooperative (NPLCC) currently lack conservation planning tools that can directly feed into the planning, design, delivery, and monitoring of ecosystems across all levels of biodiversity from genes to ecosystems. The North Pacific Forest Landscape Corridor and Connectivity Project utilized a landscape connectivity simulator (UNICOR) and a genetic simulation program (CDPOP) to model the functional (dispersal and genetic) connectivity in the North Pacific Landscape. The outputs from these programs indicated areas with high potential for landscape and genetic isolation and low probability of dispersal and colonization. In addition, this...

Decision support for climate change adaptation and fire management strategies for at risk species in southern California

This project integrates fire risk models, species distribution models (SDMs) and population models with scenarios of future climate and land cover to project how the effects of climate-induced changes to species distributions and land use change will impact threatened species in fire-prone ecosystems. This project also identifies and prioritizes potential management responses to climate change (e.g. assisted colonization, fire management, land protection, dispersal corridors). Anticipated products include: 1) maps (digital and hard copy) of habitat suitability under current and future climate change, current and future projected urban growth and combinations of climate change and future projected urban growth, under...

Columbia Plateau Climate-Gradient Corridors Analysis

The dataset was produced by Washington Wildlife Habitat Connectivity Working Group (WHCWG) as part of their Columbia Plateau Climate-Gradient Corridors Analysis (WHCWG 2013). The purpose of layers created using the climate gradient linkage-modeling method (Nuñez et al. 2013) is to help inform conservation practitioners, land use planners, and interested stakeholders in their understanding of areas likely to be important for biota as species adapt their distributions to climatic change. The results using this method are exploratory and intended to be broad-scale and generic in nature, and are not intended to direct conservation resources to specific locations or organisms.

Landscape Connectivity of a Sagebrush Obligate: Functional Continuity of Habitat for the Pygmy Rabbit

FY2014Land management agencies seek to understand how organisms use the landscape in order to develop management strategies that maintain healthy, resilient communities that have the ecological and evolutionary potential to respond to climate change. An ideal approach to understanding how organisms move through the landscape is by inferring ongoing and historic movements from patterns of genetic continuity that characterize regional sets of populations. From patterns of genetic connectivity we can infer the habitat and landscape characteristics that facilitate animal movement and species range shifts over both short and long timescales. Knowing the spatial distribution of critical linkages or corridors allows conservation...

Potential movement paths for male grizzly bear (Ursus arctos) dispersal between the Northern Continental Divide and Greater Yellowstone Ecosystems, 2000-2015

For several decades, grizzly bear (Ursus arctos) populations in the Greater Yellowstone Ecosystem (GYE) and the Northern Continental Divide Ecosystem (NCDE) have increased in numbers and range extent. Whereas the NCDE population is contiguous with grizzly bear populations in the Canadian Rocky Mountains, genetic evidence suggests the GYE population remains isolated. Recent analyses indicate the effective population size of GYE grizzly bears has increased and is approaching levels needed for long-term viability. With only ~110 km distance separating current estimates of occupied range for these populations, the potential for immigration into the GYE from an NCDE migrant, or vice versa, is likely greater now than...
