Connectivity Analysis Toolkit (CAT)

Mapping habitat linkages and ranking sites for their contribution to landscape connectivity

The Connectivity Analysis Toolkit (CAT) is a freely available software that provides new tools for both linkage mapping and landscape-level 'centrality' analysis. Conservation biologists have long recognized that natural areas that are linked into networks are often more effective than isolated areas at preserving certain components of biodiversity. Although in the past connectivity usually was considered in a static sense as habitat corridors, we now recognize that planning for connectivity requires incorporating process as well as pattern into conservation planning, and that connectivity can be achieved by means other than corridors. Planners and biologists are increasingly recognizing that existing corridor mapping tools, such as included in commercial GIS software, may not be flexible enough to incorporate new knowledge on patterns of animal movement and ecological processes.

Centrality refers to a group of landscape metrics that rank the importance of sites as ...
