Gnarly Landscape Utilities

Gnarly Landscape Utilities is an ArcGIS toolbox designed to support some of the less-glamorous tasks involved with connectivity modeling. It includes tools for creating resistance and habitat layers and core area mapping. The core area mapping functionality was formerly packaged as the HCA Toolkit. We created the tools to support connectivity analyses by the Washington Wildlife Habitat Connectivity Working Group as well as work by the Western Governors' Association and the Nature Conservancy. They can be used to create resistance, habitat, and core area maps used by Linkage Mapper, Circuitscape, and other connectivity software packages.
