Restoration of peatland is increasingly seen as a valuable and cost-effective way to help limit climate change, but some afforested peatlands have seemed impossible to restore due to underground cracks that drain away water. Now, recent trials of new techniques for rewetting cracked peat have shown promising results.
Peatlands provide globally important benefits, such as helping to regulate our climate and water, and providing valuable wildlife habitats. However, forestry operations and other land use can sometimes result in a degradation of their soil and an overall release of carbon. National plans in Scotland and Wales now propose peatland restoration on an unprecedented scale, while in England considerable peatland research is underway alongside restoration work.
Forest Research’s recent trials have shown that new trenching techniques can form a barrier that prevents water drainage through underground cracks, allowing successful rewetting of afforested sites previously regarded as unrestorable.
Project leader, Russell Anderson, explains: “We created barriers to prevent water draining away by digging trenches deeper than the underground cracks and repacking them with peat. In some cases, we also added a plastic membrane lining one side of the trench. We carried out our trials at two different sites – a lowland raised bog and a blanket bog. In both sites, we saw a dramatic rise in the underground water level after applying the treatments, both with and without the membrane.”
Restoring peatland brings many benefits, including:
