Salix, a company involved in spillway and shoreline protection, silt removal (lake desilting/dredging), wetland ecological enhancement and habitat creation schemes, has just completed a project to help to improve wildlife habitats on a section of the chalk River Nar at Pentney, near Kings Lynn in west Norfolk.
Working together with the Norfolk Rivers Trust, Salix has re-graded the river’s channel in a 440-meter section using gravel, excavated several pools, re-profiled the banks and introduced large wood features to create more variance in the river’s profile, improving the hydraulic variability and consequently the range of habitat.
Emily Long, of the Norfolk Rivers Trust , said: “ Chalk-streams are globally rare river systems and the River Nar is arguably Norfolk’s most unspoilt and beautiful chalk river.
“These works are part of a plan designed to help us preserve and enhance its rich and diverse ecology, to achieve what is termed “Good Ecological Status or Potential” under the European Water Framework Directive.”
The whole river is a Site of Special Scientific Interest (SSSI) and in recent years, the management of the River Nar has been subject to extensive investigation and consultation.
