Restored meander

Project summary

Edit project overview to modify the project summary.

This site is a part of New Forest LIFE project. The aim of the project at this site was to develop a restoration scheme for the river that would balance the Commoner’s aspirations for floodplain grazing with the conservation objections of the New Forest SAC. Works contained the excavation and reinstatement of former meandering channel, installation of a clay plug 20-30cm higher than the surrounding floodplain and removal of weed from a 350m length of channel.
