Project summary
Historical straightening and changes in land management which aimed to improve agricultural production has created a channel which is currently classified as “poor” by the WFD. The channel also causes occasional flooding in Eddleston and Peebles when rainfall is heavy.
Restoration design aims to restore natural physical habitats both in the river corridor and the wide catchment, to achieve “good” WFD status. A secondary aim is to reduce the current level of flood risk.
Restoration strategy measures include: planting of riparian and floodplain forests, breaching embankments to create flood storage areas, re-meandering of the channel, introduction of large woody debris, creating local ponds and wetlands and setting fences back from the banks. Monitoring is in place to establish baseline conditions for rainfall and surface groundwater flows as well as water quality and ecology. Proposals and planning for "phase 2" of the project, which will involve implementation of some restoration plans are on-going. A demonstration trial reach is currently planned for Darnhall Farm, specifically to reduce flooding risk downstream.
A partnership of local and national organisations is coordinated by Tweed Forum, and includes the Scottish Government, Scottish Environment Protection Agency, Dundee University, Scottish Borders Council, National Farmers’ Union of Scotland, the British Geological Survey, the Forestry Commission, Scottish Natural Heritage, the Tweed Foundation and the Environment Agency of England.
