Project summary

Edit project overview to modify the project summary.

The New Forest is one of the largest remaining areas in western Europe supporting a mosaic of heathland, wetlands and semi-natural forest. It has been designated as a Special Area of Conservation (SAC) under the Habitats Directive in 2004 and has been a National Park since 2005. In 2003, with 40% EU LIFE 3 funding, a 4-year project began to restore the streams and wetlands within the Lymington River, Avon Water and Hampshire Avon catchments. This involved reinstating the characteristic sinuous course of the streams, adding large wood to channels, reconnecting floodplains and old meanders and restoring the characteristic wetlands and riparian forest. A total of 10 km of degraded, straightened rivers were restored through floodplain reconnection, reinstating or reconnecting old meanders, and adding wood to the channel (upper tributaries of the Lymington River only). These restoration measures together resulted in a 21% reduction of flood peak magnitude and a 33% increase in flood peak travel time for flows that were less than 1m3s-1 (equal to a 2-year recurrence interval). The project also resulted in the restoration of 261ha of riparian woodland, 18ha of bog woodland, 184ha of valley mires and 141ha of wetland habitats.
