Temperature-only Climate Gradient Corridors

Metadata Updated: November 12, 2020

These data represent a normalized least-cost corridor mosaic (see WHCWG 2010 and McRae and Kavanagh 2011) calculated using temperature gradients following the climate gradient linkage-modeling methods outlined in Nunez (2011), using an adapted version of the Linkage Mapper software (McRae and Kavanagh 2011). These data are depicted in Figure 5a in Nunez (2011).

This GIS dataset is one of several climate connectivity analyses produced by Tristan Nunez for a Master's thesis (Nunez 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 Change Subgroup of 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 analysis quantifies connectivity patterns to address climate change for Washington State and neighboring areas in British Columbia, Idaho, and Oregon. Grid cell size is 1000 meters x 1000 meters. This connectivity analysis is in raster format. It should be displayed in conjunction with vector layer of Landscape Integrity Core Areas developed by the WHCWG (WHCWG 2010).
