Summary

These two datasets represent a normalized least-cost corridor mosaic (see WHCWG 2010 and McRae and Kavanagh 2011) calculated using (1) temperature gradients and a landscape integrity resistance raster, or (2) temperature gradients only, following the climate gradient linkage-modeling methods outlined in Nuñez (2011), using an adapted version of the Linkage Mapper software (McRae and Kavanagh 2011). This GIS dataset is one of several climate connectivity analyses produced by Tristan Nuñez for a Master's thesis (Nuñez 2011). The dataset was produced in part to assist the Climate Change Subgroup of the Washington Wildlife Habitat Connectivity Working Group (WHCWG). The core areas in the map lie in Washington State and neighboring areas [...]

Purpose

The purpose of layers created using the climate gradient linkage-modeling method (Nuñez 2011) is to help inform conservation practitioners, land use planners, and interested stakeholders in their understanding of areas likely to be important for biota as species adapt their distributions to climatic change. As noted in Nuñez (2011), the results using this method are exploratory and intended to be broad-scale and generic in nature, and are not intended to direct conservation resources to specific locations or organisms. The purpose of this specific layer, which is based on both temperature gradients and human land use patterns (landscape integrity), is to illustrate routes on the landscape between landscape integrity core areas that provide for unidirectional change in mean annual temperature between the core areas while avoiding areas of low landscape integrity (e.g., agricultural, urban, or transportation land use areas).
