Linkage Networks’ Synthesis Analysis The focal species and landscape integrity approaches identify habitat concentration areas (HCAs) and core habitats, respectively, and areas of the landscape important for connecting them. As in the Statewide Analysis and the Analysis of the Columbia Plateau Ecoregion (WHCWG, 2010, 2012), we consider that a linkage network consists of the combination of all the HCAs and the linkages modeled for a particular focal species, or core areas and modeled linkages for landscape integrity (WHCWG, 2010). These networks are useful individually, informing decisions pertaining to maintaining and restoring connectivity for the particular focal species (or species considered similar enough in...

At the statewide scale, we are looking for patterns of habitat distribution that dominate large landscapes. This can be thought of as a view of the land from 50,000 feet above the Earth’s surface. This view is interpreted through the behaviors and natural histories of some of Washington’s more mobile vertebrate wildlife, using computer models and our best understanding of what influences these species in their movement choices and the ways in which landscape features contribute to their survival and well-being. At this scale, we have analyzed the landscape with two approaches: a functional focal species approach and a structural landscape integrity approach. The statewide analysis is a first-step toward identifying...

These data are an appended version of the Landscape Integrity Core Areas vector map developed as part of the Washington Habitat Connectivity Working Group (2010) landscape integrity analysis. The average mean annual temperature, standard deviation of mean annual temperature, and additional statistics were calculated for the pixels in each core area and appended to the core area attribute table.Mean annual temperature statistics were appended to the Landscape Integrity Core Areas map as part of climate connectivity analyses produced by Tristan Nuñez for a Master’s thesis (Nuñez 2011) while a student at the School of Forest Resources at the University of Washington. The dataset was produced in part to assist the Climate...

Formed in 2007, the Washington Wildlife Habitat Connectivity Working Group (WWHCWG) is an open collaborative science-based effort to produce tools and analyses that identify opportunities and priorities to provide habitat connectivity in Washington and surrounding habitats (https://waconnected.org). The WWHCWG began with a Statewide Habitat Connectivity Analysis, which highlighted several regions of the state that would benefit from finer-scale analyses. The group has since conducted analyses across many of those regions. The US Fish and Wildlife Service provided funding to develop habitat connectivity models for one of the remaining regions–Washington’s Cascades to Coast region. The goal of this project was to...

The Washington Connected Landscapes Project: Cascades to Coast Analysis produced the following geospatial data layers for landscape integrity: (1) a raster dataset depicting habitat suitability, (2) a vector dataset of core habitat depicting areas of high concentrations of suitable habitat, (3) a raster dataset depicting the landscape’s resistance to movement, (4) a raster dataset of cost-weighted distance depicting the permeability of the landscape for movement between core habitat areas, (5) a vector dataset depicting the least-cost paths between core habitat areas, and (6) a raster dataset depicting the least-cost corridors between core habitat areas. The data layers are provided in multiple file formats that...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
