Borrowdale Moss is an extensive area of blanket bog occupying the head of Borrowdale and the heads of the adjacent valleys of Crookdale and Bannisdale, immediately south of the large blanket bogs of the Shap Fells SSSI. Whilst scattered patches of intact blanket bog remain over the majority of the site extensive linear peat hags have left an undulating surface with extensive species-poor vegetation on eroded sections and exposed dry peat.
The Borrowdale Moss Peatland Restoration project is designed to address diffuse pollution issues concerning the River Sprint (tributary of the Kent) and Borrow Beck (tributary of the Lune). In particular this project will address the issue of degraded peatland in the headwaters. Drain-blocking and re vegetation of bare peat has been shown to reduce particulate organic carbon (POC) and dissolved organic carbon (DOC) downstream, reduce carbon loss and there is growing evidence of a hydrological response changing to a less ‘flashy’ character. Peatland restoration therefore benefits not only peatland soils, vegetation and hydrological ecosystem services but also stream water quality and biodiversity downstream.
Through an extensive restoration programme involving grip blocking, re-profiling and re-vegetation of bare peat over a site greater than 800 hectares, this project will address key diffuse pollution issues in the headwaters of a number of watercourses. The project aims to move from moderate to good the River Sprint and to ensure no deterioration of Borrow Beck from good water body status. There is a real danger that unless the degraded and eroded peat on the blanket bog at the head of this valley is not addressed, that the consequences on water quality will continue to rise. The restoration will also complement and help the integrity of the adjoining Shap Fells SSSI and Lake District High Fells SAC that is currently undergoing similar works. A walkover of the site has shown that the area is extensively ‘hagged and gullied’ with areas of bare peat. Aerial photographs have identified extensive grip systems.
This project, in combination with River Restoration Strategy works being undertaken by partners, will enable good status to be achieved by tackling reasons for failure (diffuse pollution), particularly in the form of sediments. It will also meet targets for flood alleviation.
