Restoring Humberhead Peatlands: An Ongoing Story

Under Natural England’s management, Thorne Moors National Nature Reserve (NNR) in the north of England has undergone a remarkable recovery.

Bare peat represents the death of peatlands. After decades of drainage and extraction, Thorne Moors had no shortage of it. Yet under Natural England’s management the National Nature Reserve (NNR) has undergone a remarkable recovery. Much of the Lowland Raised Bog has revegetated, and although the NNR team continues to grapple with hydrological challenges and scrub encroachment, the overall trajectory is positive.

From 2021 the EU-funded LIFE Moor Space project began working on Goole Moor, part of the wider Thorne Moors complex. Early drone surveys revealed the urgent need to address bare peat that remained dry in summer and waterlogged in winter. This situation gave no opportunity for bog plants to colonise the bare peat.

At the outset of LIFE Moor Space, we had 26 hectares of bare peat, fragmented across the 400-hectare project area. Restoration has involved targeted actions rather than wholesale change to the landscape, building on the iterative nature of peatland restoration. 

As peatland practitioners know, restoration begins with stabilising the water table. LIFE Moor Space worked with contractors to design a new low-cost adjustable weir, that has now been installed in drainage channels, allowing targeted management of the largest pools. With hydrology under control the team moved to the next stage: plug planting. To date NE staff and volunteers have planted 18,652 sphagnum plugs, including S. capillifoliumS. fimbriatumS. palustreS. papillosum, and S. subnitens. These were complemented by 11,536 cottongrass plugs—8,652 Common Cottongrass (Eriophorum angustifolium) and 2,884 Hare’s-tail Cottongrass (Eriophorum vaginatum).

The cottongrass was arranged in a diamond pattern, with one Hare’s-tail to every three Common Cottongrasses, designed to shelter the sphagnum plugs planted at the centre. Whether this method succeeds on Goole Moor remains to be seen but with hydrology stabilised it offers the best chance of rapid revegetation. Despite an exceptionally dry summer in 2025, most planting sites are thriving. Even more so now that rainfall has returned.

Water management remains challenging. During the EU-funded That’s LIFE project (2014–2018) an Archimedes Screw pump was installed to remove surplus water. Although counterintuitive for peatlands that depend on wet conditions, prolonged flooding can smother new vegetation and prevent colonisation of bare peat. To avoid this LIFE Moor Space and the NNR team has decided to run the pump slowly through winter to maintain acceptable water levels. The system offers flexibility and can be paused at any time; however, the experience of 2024—when a single storm overwhelmed both the site and nearby drainage networks, leaving recovery efforts stalled for much of the winter—underscores the importance of careful regulation.

With funding secured until 2027, the LIFE Moor Space project plans another round of planting in 2026, alongside an ambitious programme to translocate adult bog plants of different species from across the moors.
