Description:

Habitat concentration areas (HCAs) are defined as significant habitat areas that are expected or known to be important for focal species based on survey data or habitat association modeling (WHCWG 2012). HCAs provide locations from which to model linkages.

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 appropriate 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, but they rely on inherently 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 Section A (Chapter 2), as well as Section C in the WHCWG Cascades to Coast 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 2010 to 2020. 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 additional details, the data user should note Section A (Chapter 2), particularly Table 3 in the WHCWG Cascades to Coast report. See metadata Credits for the report. APPROPRIATE SCALE OF USE: The raw GIS data obtained by the WHCWG Cascades to Coast 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. Given the wide ranging source scales and post-processing we do not recommend application of linkage data at scales larger than 1:100,000.
