In a step towards implementing our Vision, SREP completed a statewide assessment of wildlife linkages in collaboration with the Colorado Department of Transportation (CDOT), the Federal Highway Administration, The Nature Conservancy, and Colorado State University, identifying and prioritizing wildlife linkages across the state of Colorado. The goal of this work is to provide transportation planners, state and federal agencies, community leaders, engineers, and conservationists with a statewide vision for reconnecting habitats that are vital for maintaining healthy populations of native species. Both the Federal Highway Administration and CDOT have begun promoting wildlife crossings in their transportation plans...

Canada Lynx modeled corridors in Colorado by the Southern Rockies Ecosystem Project (now Center for Native Ecosystems) encompassing the most important expert and model identified corridors from the Linking Colorado's Landscapes project that cross highways. The modeled corridors represent the corridors that were modeled using the Corridor Design tool http://corridordesign.org
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...

The California Department of Transportation (Caltrans) and California Department of Fish and Game (CDFG) commissioned the California Essential Habitat Connectivity Project because a functional network of connected wildlands is essential to the continued support of Californias diverse natural communities in the face of human development and climate change. The Essential Connectivity Map depicts large, relatively natural habitat blocks that support native biodiversity (Natural Landscape Blocks) and areas essential for ecological connectivity between them (Essential Connectivity Areas). This coarse-scale map was based primarily on the concept of ecological integrity, rather than the needs of particular species. Essential...

Powerlines in the western United States. Data was obtained from the ICEBMP existing utility corridors data set. These data were reprojected to USA_Contiguous_Albers_Equal_Area_Conic_USGS_version and clipped to the MAR REA boundary.

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...

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...
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...

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.

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...

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...

The Wildlife Linkage Habitat Analysis uses landscape scale data to identify or predict the location of potentially significant wildlife linkage habitats (WLH) associated with state roads throughout Vermont. For purposes of this project, WLH is a term used to describe those habitats associated with Vermont roads where wildlife move, migrate, and access various other habitats and parts of their range (similar to, but broader than, wildlife corridors). This project relied on available GIS data including: (a) land use and land cover data; (b) development density data (E911 sites); and (c) contiguous or "core" habitat data from the University of Vermont. The GIS conserved lands data was also used for this project as...

The Transboundary Madrean Watersheds Landscape Conservation Design (LCD) was developed as part of an effort initiated by the Desert Landscape Conservation Cooperative (Desert LCC). The Desert LCC was a program of the Bureau of Reclamation and the US Fish and Wildlife Service to address large-scale landscape conservation in the southwestern United States and northern Mexico. This collaborative effort brought together managers, stakeholders, communities, and others to work toward sustaining resilient landscapes capable of responding to environmental challenges and supporting natural and cultural values for current and future generations.The Madrean Watersheds LCD area spans the states of Arizona, New Mexico, Sonora,...
