In the heart of the Fens, High Fen Wildland, a 292-hectare site in Methwold, Norfolk, has embarked on a transformative journey toward ecological restoration since its acquisition by the nature restoration company Nattergal in December 2022. Once a commercially unviable agricultural expanse, the land, characterised by its unique sandy peat soils, struggled to sustain arable crops and seasonal daffodil cultivation. As farming became increasingly difficult in this naturally wet landscape, the region transitioned into a seasonally flooded grassland, maintained through an agri-environment scheme.

Nattergal’s ambitious project aims to rejuvenate this ecologically significant area by creating a diverse mosaic of wetland habitats, including reed beds and willow carr, while implementing essential rewetting initiatives. This strategic rewetting not only aims to bolster biodiversity but is also crucial for mitigating carbon emissions, as waterlogged peatlands serve as vital carbon sinks. Matthew Hay, Nattergal’s natural capital manager, articulated the vision, stating, “Our idea is simple – rewet as much peatland as we can, and then allow the wetland habitats to recolonise.”

The funding for this extensive restoration effort is fundamentally tied to innovative financial models. The company plans to sell “key ecosystem services,” particularly through Biodiversity Net Gain (BNG) initiatives and peatland carbon credits. BNG frameworks mandate developers to offset habitat loss from construction projects and require at least a 10% net gain in biodiversity. This creates a market where companies can invest in the restoration of natural habitats, thereby addressing their environmental footprint while contributing to ecological restoration.

Hay reflected on the historical context of the Fens, noting that prior to the widespread drainage efforts in the 1700s, the region thrived as a biodiverse wetland ecosystem, home to myriad species. The conversion of these lands into one of Britain’s most fertile agricultural areas came at the cost of significant ecological degradation, with greenhouse gases now emitting from the drained peatlands – a stark reminder of the critical balance between agricultural productivity and ecological health.

The unique hydrological characteristics of High Fen provide an advantageous backdrop for Nattergal’s restoration goals. Surrounded by three watercourses – the River Wissey, Methwold Lode, and a strategically situated cut-off channel – the site offers “hydrological control.” Hay explained that this configuration enables the team to raise the water table without adversely affecting neighbouring lands, thus preserving significant carbon storage within the peat.

A robust network of water monitoring stations has been implemented to analyse the site’s hydrology, guiding targeted rewetting efforts. Site manager Frank Street described the technical approach: “Most of the water moves underground… We can build this subterranean wall to stop the water from moving,” thereby maintaining the necessary water levels for effective peatland restoration.

The endeavour’s long-term prospects are promising, with Nattergal already registering 548 BNG units for the site, of which a small portion has been sold. Chief commercial officer Claire Traynor expressed enthusiasm over the healthy demand for these units, having observed significant local development that will drive continued interest in biodiversity credits linked to this unique restoration project.

Furthermore, rewilding initiatives like this are part of a broader movement across Europe that recognises the invaluable ecological services provided by peatlands. Restoration not only contributes to climate change mitigation by reducing carbon emissions but also enhances habitats for wildlife, potentially increasing opportunities for eco-tourism and community engagement.

As the restoration of High Fen Wildland progresses, it serves as a beacon of hope and a model for future projects. By blending pioneering financial frameworks with a commitment to ecological restoration, this initiative embodies the possibility of a more harmonious coexistence between human activity and the natural world, striving to bring back a rich biological tapestry to an area once celebrated for its diverse wildlife.
