Conservefor, A specialist peat bog restoration contractor, was appointed by Natural England to undertake a peat bog restoration project at Roundsea Moss near Haverthwaite in Cumbria.
Roundsea Mosses have been extensively cut over for domestic peat use and drains installed as a prelude to commercial extraction which did not occur. The peat cutting and drainage has dried out the surface of the moss resulting in pine and birch trees and scrub colonising.
The aim of the project was to raise the water level across the site by approximately 100mm. To achieve this aim, our peat bog restoration team used bespoke 7 Tonne 360 excavators with power tilt attachments and 900mm wide tracks and 13 tonne excavators with 1.2m wide custom made tracks.
Our team began by creating cells made from peat bunds following the topography of the wetland. The cell size varied from 20 m sq. to 10m sq. depending on the contours of the land. This ensures an even level of water across each cell. The bunds were created using active, wet peat from inside the soon to be flooded cell and raised to a height of 100mm and sealed into the peat under the line of the bund. Vegetation removed during the borrow pitting process was then placed over the bund to prevent the peat oxidising. Desiccated peat and any stumps encountered whilst building the bund were placed into the borrow pit to reduce the visual impact caused by the construction.
Our knowledge and experience from working on many sensitive sites has enabled our team to develop specialist restoration techniques to aid the recovery of badly damaged peatlands. We offer professional advice and support service and we can deliver projects to meet your needs and aspiration for the site. We believe that every site is different and the chosen method of restoration is important to ensure successful results.
