IMGP6954.JPG 2005-01-01Z 2453371.5 Complete The River Avon and its major tributaries are recognised as a Special Area of Conservation for their rare habitats and species, including flowing water vegetation (eg. ranunculus and water-crowfoot), Atlantic salmon, Bullhead, brook and sea lamprey, water vole and otter. The restoration project at East Chisenbury is part of the Wessex Chalk Streams PRoject (WCSP), which began in 1999 - a partnership between the Wiltshire Wildlife Trust, Natural England, the Environment Agency, Wessex Water and the Wiltshire Fishery Association. the project is focused on restoring river and wetland habitat, while helping to achieve targets under the Wiltshire & Swindon and Wessex Water Biodiversity Action Plans (BAPs). The project at East Chisenbury was completed in two phases: * Phase 1 (2005): Trial project to restore a 70m reach below Compton Bridge which had been subject to heavy dredging - Total Cost: £30,000. * Phase 2 (2009): Restoration of a 650m reach upstream of Compton Bridge. Involved use of successful 'coir net' technique to re-introduce sinuosity and hydromorphological function to the overwide channel. *Further information regarding aims, objectives, project successes and pre/post restoration project photos are available in the attached Wessex Chalk Streams Project report (see bottom of page).
