Traditional metrics have been calculated using landscape patterns of composition and configuration. The objective of this study was to examine an alternative process-based approach using the cost of traversing a landscape as a proxy for fragmentation and compare it with the traditional approach. One thousand binary landscapes varying in composition and configuration were simulated, and least-cost path analysis provided the data to calculate the process-based metrics, which were compared with the computed pattern-based metrics. The process-based quantification of landscape fragmentation was more sensitive to landscape fragmentation than a pattern-based quantification. My study provides a methodological foundation for further studies as it is not associated with a specific species or ecological process, and thus can be easily adapted to numerous settings.Author owns copyright, except where explicitly noted.
