Summary

Action: Restore/create river channel (multiple interventions)

A site comparison study in 2007–2012 of two reaches of a creek in New York, USA (Buchanan et al. 2014) reported that a restored reach contained less moss/algae than a natural reference reach after two years, but a similar amount of moss/algae to the reference reach after seven years. Data were reported as semi-quantitative Pfankuch scores. Statistical significance was not assessed. Methods: In 2005, a degraded, eroding reach of Six Mile Creek was restored using multiple interventions: reprofiling the channel, adding flow control structures (rock vanes stretching across the whole channel or part of it), reprofiling the floodplain to a shallower slope, and planting/sowing vegetation (both woody and herbaceous) on the floodplain. The restoration aimed to stabilize the channel, reduce erosion and reduce flooding of nearby properties, in addition to enhancing fish and wildlife habitat. Mosses/algae in the channel were visually surveyed in summer 2007 and spring 2012, along 20 bank-to-bank transects: 10 in the roughly 1-km-long restored reach and 10 in a reference reach upstream, representing target conditions.
