Abstract:
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). The statewide analysis quantifies current connectivity patterns for Washington State and adjacent areas in British Columbia, Idaho, Oregon and a small portion of Montana. Available WHCWG raster data include model base layers, resistance, cost-weighted distance, landscape integrity networks, focal species networks, and focal species guild networks. Grid cell size is 100meters x 100meters. Habitat concentration areas, landscape integrity core areas, and linkage maps reside in raster and vector format.
Project background can be found in the report:

This raster contains 5 map classes depicting ranges of acres per dwelling unit. The raster was used in focal species and landscape integrity resistance surface development.
USA and British Columbia data were developed using different methodologies. The USA data were drawn from a published housing density raster. The Britsh Columbia data were built using dwelling unit census statistics and spatial data partitioning the landscape into likely areas of human population.

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. Despite this, the WHCWG makes no guarantee concerning the content, accuracy, completeness, or the results obtained from queries or use of WHCWG data, other than those for which the data was developed and its intended use. The WHCWG shall not be held liable for improper or incorrect use of the data described and/or contained herein. The WHCWG model input data were obtained from a wide range of state and federal jurisdictions in the USA, as well as from Canadian federal and provincial levels of government. 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 data set 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 statewide 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 Chapters 2 and 4 and appendices in the WHCWG December 2010 final report for further details. Online linkage to final report: http://www.waconnected.org
