Contribution of connectivity metrics to the assessment of biodiversity – Some methodological considerations to improve landscape planning

摘要: Abstract Land use change and the resulting physical functional disconnection of ecological networks are some driving forces biodiversity loss. Landscape planning environmental assessments essential instruments for addressing such problems. Methods quantifying predicting impacts fragmentation on needed, as methods deriving objectives measures in landscape process. While a number different methodologies regarding network analysis graph theory provide tools analyzing networks, is tool that may be helpful reducing negative finding appropriate solutions These can used evaluation process, to analyze visualize possible scenarios participation or define areas most important preserve enhance biodiversity. Using example three target species Saxony, Probability Connectivity Index (PC) connectivity index potential examined. Implementation requirements process described.
