Ecological benefits of creating messy rivers

摘要: This study explores the ecological effects of a woody bank revetment in an upper reach River Manifold, Staffordshire, UK. Significantly higher abundances macroinvertebrates were recorded immediately downstream deciduous compared with reference site, 3 out 4 months surveyed. The watercourse at also had significantly species richness aquatic fauna than site some months. While there was no evidence spatial or temporal variation within during period, biodiversity sub-sample collected from zone more varied: Ephemeroptera/Plecoptera/Trichoptera (EPT) close to bank. Additionally, three relatively rare mayfly exclusively associated (Baetis niger, Ameletus inopinatus and Siphlonorus alternatus). Water temperatures found be lower proximity revetment. These micro-scale suggest that revetments could deliver range conservation benefits, not least habitat creation mitigation rising river under climate change.
