Hierarchical multi‐taxa models inform riparian vs. hydrologic restoration of urban streams in a permeable landscape

摘要: The degradation of streams caused by urbanization tends to follow predictable patterns; however, there is a growing appreciation for heterogeneity in stream response due the local geoclimatic context. Furthermore, building evidence that mildly sloped, permeable landscapes respond uncharacteristically urban stress calling more nuanced approach restoration. We evaluated relative influence local-scale riparian characteristics and catchment-scale imperviousness on macroinvertebrate assemblages flat, landscape Perth, Western Australia. Using hierarchical multi-taxa model, we predicted outcomes stylized restoration strategies increase integrity at scale or decrease influences catchment scale. In show can structure greater degree than managing imperviousness. also observed an interaction between effect such increased was enhanced lower levels This study represents one few conducted first aimed informing adding Urban Stream Syndrome its importance
