Physical effects of habitat restoration
In 2000, Pisces Conservation carried out a major series of surveys on lowland streams in Wiltshire and Dorset, to assess the effect on macroinvertebrate and plant communities of habitat restoration and channel restructuring, originally intended to improve habitat quality for fish. Surveys were carried out at 22 sites throughout summer 2000.
Invertebrate samples, botanical surveys, and measurements of physical parameters such as weed cover, shading, depth and flow rate were obtained from restored and unrestored stretches of river at each site. Pisces Conservation's own software
was later used to analyse the collated data, and draw conclusions on the effect of restoration on diversity and species richness.
