Unique Chalk Stream Established in Norfolk to Enhance Wildlife Habitat

Efforts to restore one of the world’s rarest types of river ecosystems are yielding promising results, as wildlife begins to flourish once more in the wetlands of Keswick Marsh, situated in Norfolk. This initiative is focused on enhancing the habitat of the River Yare, a chalk stream that is among only 210 of its kind globally, with a significant concentration of 58 found in the East Anglia region.

Restoration of the River Yare Ecosystem

The collaborative project, spearheaded by the Environment Agency, the Norfolk Rivers Trust, and Water Resources East, has successfully transformed over 7 hectares of riverbank and floodplain. By reconnecting the river with its surrounding landscape, the restoration efforts have created a dynamic environment conducive to the thriving of various species.

With the introduction of new ponds, shallow pools, and reconfigured ditches, water can now naturally spread across the floodplain during winter months and retain moisture for extended periods during dry spells. This restoration not only revitalises the natural water cycle but also mitigates flood risks downstream while fostering the diverse habitats essential for numerous wetland species.

Amy Prendergast, the catchment delivery manager at the Environment Agency for East Anglia, expressed her enthusiasm for the project, stating, “Collaborating with Norfolk Rivers Trust to establish new wetland features at Keswick Marsh has been a remarkable endeavour, providing crucial habitats for wildlife on the outskirts of Norwich.”

Positive Impact on Local Wildlife

Donna Dean, the restoration and catchment development manager at Norfolk Rivers Trust, noted the immediate impact of the restoration on local wildlife. Species such as egrets, coots, shelducks, newts, dragonflies, and even a little ringed plover have been recorded visiting the area, some of which represent entirely new sightings for the site. Dean remarked, “It’s truly gratifying to see wildlife returning so swiftly, and we are eager to observe the ongoing establishment of this vibrant ecosystem.”

The design of the wetlands intentionally incorporates edge habitats, where land meets open water, enhancing the potential for biodiversity. This development is set to directly benefit inland wetland birds, amphibians, and a range of wetland flora.

Support and Funding for Sustainable Solutions

Hannah Gray, programme manager at Water Resources East, highlighted the significance of funding from the Norfolk Water Strategy Programme (NWSP), which is supported by the Royal Bank of Canada. Gray stated, “The NWSP is working collaboratively across Norfolk to implement nature-based solutions that enhance water security. The work undertaken at Keswick by Norfolk Rivers Trust is a vital step towards realising our shared vision.”

The 20-acre site was generously provided by Lady Dannatt, HM Lord-Lieutenant of Norfolk, with financial backing from various entities, including the Norfolk Water Strategy Programme, Norfolk County Council, Anglian Water, and the Environment Agency.

Preparing for Future Environmental Challenges

As the UK faces the dual challenges of prolonged drought conditions and the prospect of a wetter winter, the Environment Agency remains vigilant. The agency is prepared to address both ongoing drought scenarios and potential flooding incidents as the seasons change.

The total investment for the project amounted to £97,764, with the on-ground delivery and species mitigation works completed within three weeks. Preliminary feasibility studies, including habitat and species surveys and securing funding, took an estimated two to three years.

The Norfolk Water Strategy Programme aims to enhance water management in the region’s chalk catchments by increasing investment in nature-based solutions. For further information, please visit the respective websites of the Norfolk Rivers Trust and the Environment Agency.

As part of its ongoing commitment to flood preparedness, the Environment Agency launched Flood Action Week on 12 October, encouraging communities to take proactive measures to safeguard against flooding.
