This dataset was created by overlaying connectivity model outputs for grizzly bear, black bear, lynx, wolverine, forest specialist species, and forest biome dwellers where they intersect the region’s major roads. It was used in conjunction with future traffic volume projections to identify priority sites for mitigating road impacts on wildlife. This project investigated the potential impacts of future housing development on traffic to determine where increased traffic from housing development will impact habitat connectivity for large carnivores. The focus of this study was Flathead and Lincoln counties in northwestern Montana. The main goal was to maintain wildlife habitat connectivity across transportation corridors...

Northeast Region Marsh Migration is one of a suite of products from the Nature’s Network project. Based on sea level rise (SLR) analysis by NOAA, this dataset depicts potential marsh migration zones at various sea level rise scenarios from 0-6’. Identification of suitable uplands adjacent to tidal wetlands is based on topography, habitat type, land use, and development, and can be used for facilitating marsh migration through land protection and/or management. The NOAA Coastal Change Analysis Program (CCAP) mapped the initial (current) distribution of potential marshes and and other coastal land cover types. The Detailed Method for Mapping Sea Level Rise Marsh Migration provides the full methodology for the data...

This layer shows the results for initial analyses of the ' Connectivity' potential Conservation Target for the Freshwater Forested Wetlands Priority Resource (PR). Three datasets were used in this exploration of Connectivity: CLIP 4.0 Greenways, CLIP 4.0 Landscape Integrity, and the Local Connectedness layer, one of the core datasets in the Nature Conservancy's Resiliency Project. Each dataset provides a slightly different aspect of Connectivity. Each one of the potential data layers was masked using the PR raster to result in a spatial data layer of values within Freshwater Forested Wetlands. Further information on these analyses can be found in the Freshwater Forested Wetlands Initial Investigation of Conservation...

For more information about how these data were developed, please see the final report. 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 more dangerous for species to move through. A set of nodes for each species, with node points indicating center locations for potential source populations for the species, 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 by...

These data are the final landscape permeability data as described in the report "Conserving Nature's Stage: Identifying Resilient Terrestrial Landscapes in the Pacfic Northwest."Permeability refers to the connectivity of a focal cell to its ecological neighborhood when it is viewed as a source; in other words, it asks the question: “to what extent are ecological flows outward from that cell impeded or facilitated by the surrounding landscape?” Thus,permeability starts with a focal cell and looks at the resistance to ecological flow outward in all directions through the local neighborhood. As resistance increases, flow is impeded or stopped altogether. Areas of no resistance allow the flow to proceed until a user-specified...

Montane Conifer Connectivity of areas of low elevation and low human footprint in the North Pacific Landscape Conservation Cooperative study area. This application provides Montane Conifer Connectivity for 2000 and 2080 (A1B). The North Pacific Forest Landscape Connectivity Project uses three main geospatial layers as inputs into the creation of resistance map grids. One-km was decided as the resolution for the final resistance grids. 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...

These case study sites are detailed in the report accompanying this data layer. The case studies are intended to serve as examples of how some of the opportunities for diverse stakeholders to engage in the process of mitigating road impacts on wildlife that are described in the report might be applied on the ground, as well as other considerations that come into play in selecting sites for possible mitigation and designing mitigation solutions for those sites. Through these case studies, we illustrate potential opportunities for mitigation and partner engagement for each of the four alternative priority sets identified in this study.Wildlife carcasses recorded by Montana Department of Transportation, Idaho Department...

The landscape permeability model represents the structural connectivity of sagebrush ecosystem habitat in the Green River Basin (including ~5-10 km boundary outside of the GRB. This model connects patches of habitat, across the landscape using resistances that represent the degree of human modification and slope (energetic costs), using the Multi-Scale Landscape Permeability model (Theobald et al. 2012; Theobald unpublished). We used two metrics: (a) patch importance and (b) betweeness centrality amongst patches. These metrics were summarized for each HUC12. This dataset represents the vulnerability of sagebrush ecosystem permeability to human modification summarized for each HUC12 watershed within the Green River...

This map was created from the Greenways Core Layer of CLIP 4.0. This layer was created as part of the Florida Ecological Greenways Network GIS Database. The Florida Ecological Greenways Network (FEGN) identifies the opportunities to protect large, intact landscapes important for conserving Florida’s biodiversity and ecosystem services, and serves as a backbone for biodiversity and ecosystem protection efforts in Florida. An important goal of the FEGN is to protect a functionally connected network of public and private conservation lands from the tip of south Florida to the tip of the Florida panhandle while also potentially providing functional connectivity to conservation lands in Georgia and Alabama.
