Abstract:
This vector line layer is attributed with distance measures generated from Linkage Mapper version 0.7.5 (McRae & Kavanagh 2011). Note Section 2.8 WHCWG (2012) concerning application of Linkage Mapper in the Columbia Plateau project area. None of the linkages met WHCWG modeling criteria and were attributed Inactive. Euclidean distance = shortest straight-line distance between two HCAs. Cost-weighted distance = minimum cost-weighted distance an animal can accumulate moving from one HCA to another. Cost-weighted distance is equal to the total resistance accumulated moving along the least-cost path between the two HCAs. Cost-weighted/Euclidean distance ratio = ratio of cost-weighted to Euclidean distance between two HCAs. Higher ratios mean least-cost corridors are longer or have higher resistance.
Purpose:
The “stick map” provides a schematic view of connectivity by showing linkages between habitat concentration areas as straight lines. None of the linkages met modeling criteria developed in WHCWG (2012) and were therefore attributed Inactive. The lines are attributed with Euclidean and cost-weighted distance measures to aid linkage interpretation.
Supplemental_Information:
This GIS dataset is part of a suite of wildlife habitat connectivity data produced by the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The WHCWG is a voluntary public-private partnership between state and federal agencies, universities, tribes, and non-governmental organizations. The WHCWG is co-led by the Washington Department of Fish and Wildlife (WDFW) and the Washington Department of Transportation (WSDOT). This dataset quantifies current wildlife habitat connectivity patterns for the Columbia Plateau Ecoregion in Washington, Oregon, and Idaho. Available WHCWG raster data include model base layers, resistance, habitat, cost-weighted distance, and landscape integrity. Grid cell size is 90 m x 90 m. Habitat concentration areas, core areas, and linkage maps reside in raster and vector format. Project background can be found in the report: Washington Wildlife Habitat Connectivity Working Group (WHCWG). 2012.

DATA BACKGROUND: The Washington Wildlife Habitat Connectivity Working Group (WHCWG) produced these data which represent a regional analysis that portrays conditions at a regional scale. Applying these data at finer, more local scales is likely to increase uncertainty in terms of accuracy and applicability for local land use decisions. However, for the scale at which they were developed, these products are state-of-the-art, peer-reviewed representations of landscape variables and connected habitat networks. The WHCWG expended great effort to compile the best GIS data within constraints imposed by data development costs, available compilation sources, and available staff resources. Inherent in any dataset used to develop graphical representations, are limitations of accuracy as determined by, among others, the source, scale and resolution of the data. The products and data from this analysis convey a wealth of information relevant to conservation of Washington's wildlife and though they represent the state of the art, they rely on imperfect data, knowledge, and assumptions. We strongly suggest that readers thoroughly understand our methods and the limitations of those methods prior to applying our results. The data user should note Chapter 2 and appendices in the WHCWG Columbia Plateau report. See metadata Credits for the report.
SOURCE DATA YEAR: The GIS base layers input to linkage modeling were developed from a wide variety of sources compiled over the years generally from 1999 to 2010. We would like to specify a GIS base layer compilation year for users of the connectivity data; however, the wide range of base layer compilation dates complicates such a specification. For example, land cover / land use, a major base layer, was mapped from Landsat imagery acquired from 1999 to 2003. This layer was subsequently modified by the WHCWG Columbia Plateau Ecoregion project using land cover / land use sources as recent as 2010. Likewise, transportation data were primarily obtained from the 2010 Census TIGER roads and housing density data were generated from the 2000 Census dataset. The data user should be aware that some areas experiencing rapid change over the last decade may not be captured in the modeling effort. APPROPRIATE SCALE OF USE: The raw GIS data obtained by the WHCWG Columbia Plateau project were compiled from a wide range of compilation source scales. The GIS data were post-processed at a 30 m x 30 m cell size (except housing density which had a native cell size of 100 m x 100 m). These data were compiled to 90 m x 90 m cell size prior to connectivity modeling. Given the wide ranging source scales and post-processing we do not recommend application of linkage data at scales larger than 1:100,000.
