The Area 7 mule deer population is one of the state’s largest deer herds with an estimated population of about 11,000 in 2019. This deer herd is highly important to Nevada from an economic and ecological perspective. It’s one of the longest distance deer migrations in the state of Nevada with some animals known to migrate over 120 miles during a single migration. A subset of this population, known as the “Pequop” herd, crosses a major highway (US highway 93) and an interstate (Interstate-80) twice annually during their seasonal migration. Several million dollars in wildlife crossing structures have been constructed to help these deer during their migration, yet they still face challenges to connectivity between...

Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations, are also defined. Note actual species population data to define the nodes is not used, as that data was often unavailable, and the focus is on the potential spread of the species across the SALCC region and not limited to models to known populations. Therefore, node locations were determined using an innovative approach to search for local minima in the resistance surfaces, as such areas likely represent...

The connectivity result files from Circuitscape represent the "adjusted cumulative current density" flowing across the landscape for each of several species, at a 90-meter resolution across the South Atlantic Landscape Conservation Cooperative region. Rasters are classified using quantiles with 20 categories (each 5% of region) to integer scores from 1-20. 1 = lowest 5% of the landscape, 20= top 5% of landscape Expert opinion was used to define a resistance surface for each of the target animals, with higher resistance representing map units expected to be more difficult and dangerous for species to move through.

Linkage Mapper uses GIS maps of core habitat areas and resistances to identify and map linkages between core areas. Each cell in a resistance map is attributed with a value reflecting the energetic cost, difficulty, or mortality risk of moving across that cell. Resistance values are typically determined by cell characteristics, such as land cover or housing density, combined with species-specific landscape resistance models. As animals move away from specific core areas, cost-weighted distance analyses produce maps of total movement resistance accumulated.The tool identifies adjacent (neighboring) core areas and create maps of least-cost corridors between them. It then mosaics the individual corridors to create...

Mule deer in the Izzenhood herd are part of a larger population known in Nevada as the “Area 6” mule deer population. They primarily reside on winter ranges in the Izzenhood Basin and upper Rock Creek drainages in western Elko County and northern Lander County. From their winter range, mule deer in this sub population migrate approximately 70 miles to summer ranges in the northern Independence Mountains and Bull Run Basin area. Some of the most important stopover areas are located near upper Rock Creek, Toe Jam Mountain, and Chicken Creek Summit. Challenges to this deer herd include past wildfires on winter range, conversion of native shrub habitats to exotic annual grasses, and lower primary production in some...

The Cascadia Parner Forum fosters a network of natural resource practitioners working with the NPLCC and GNLCC to guild the adaptive capacity of the landscape and species living within it. This project supported three complementary transboundary climate adaptation and habitat connectivity activities in the Cascadia region: 1) Transboundary Climate Analysis by the Washington Wildlife Habitat Connectivity Working Group, 2) WildLinks workshop, and 3) Cascadia Partner Forum.

This layer is part of an older version of the Southeast Blueprint. It combines the hubs and corridors underlying the Southeast Blueprint in the Appalachian and South Atlantic subregions. While the South Atlantic and Appalachian connectivity analyses were conducted separately using different methods, the overall approach is similar. Both use a structural connectivity framework, capturing how well natural habitat is connected in general, without using species-specific thresholds. Hubs are defined as large continuous patches of high-value areas based on an integrated prioritization of land and water. Corridors are identified through a least-cost path analysis using Linkage Mapper. You can refer to the metadata for...

This layer provides information on putative summer corridors facilitating dispersal from northern populations to patches capable of supporting Canada lynx in the Northern Rocky Mountains. These results combine resource selection, step selection, and least-cost path models to define movement corridors for lynx in the Northern Rocky Mountains. The illustrated corridors were created by using a one-mile buffer around the putative summer corridors facilitating dispersal from northern populations to patches capable of supporting Canada lynx in the Northern Rocky Mountains
Habitat and population fragmentation were among the primary factors contributing to the recent U.S. Fish and Wildlife Service decision that listing greater sage-grouse (Centrocercus urophasianus, hereafter sage-grouse) was warranted but currently precluded by higher priority actions. Increasingly, current management is focused on core or priority areas containing the highest densities of breeding birds with little regard to understanding connectivity within and among areas. The most fundamental objective of species conservation is to first identify and subsequently maintain a set of viable and connected populations. Therefore, if management emphasis on core areas is to be successful for long-term conservation, it...

This decision support tool provides spatially explicit information pertaining to modeled wildlife connectivity value across major roads, total wildlife mortality counts along major roads, carnivore mortality counts along major roads, the extent to which wildlife connectivity value and road mortality align, and potential priority sites for mitigation of road impacts on wildlife from diverse stakeholder perspectives. In the report accompanying this map document, we also discuss potential opportunities for diverse stakeholders (including departments of transportation, state and federal land managers, land trusts, citizen groups, and conservation organizations with a variety of missions) to engage in and contribute...
