Title: Bottlenecks/ pinch points on least-cost-paths
Author:
Comments: Pinch points are calculated by the Pinch Point Mapper tool, within the LinkageMapper toolbox (McRae, 2012). This tool complements the least-cost path results with electric circuit analysis by “identifying important alternative pathways and “pinch points,” where loss of a small area could disproportionately compromise connectivity” (ibid.).
Subject: Pinch points are identified to prioritize important areas for connectivity conservation at local scale (McRae, 2012). The highlighted pinch points are showing constraints of current flow on the best corridor and shows “both, the most efficient movement pathways and critical pinch points within them” (ibid.). For spatial and landscape planning it is useful to focus on the pinch points, (i.e. bottlenecks on the least-cost-paths) and prioritize them over areas that are more open and therefore less crucial for connectivity conservation.
