Coundon Wedge: Restoring a River to Its Natural Course

A landscape reconnected

At Coundon Wedge, the North Brook, one of the tributaries of the River Sherbourne, is flowing more naturally once again. Following “Stage Zero” restoration works in 2023, and further enhancements since, this valued green space has evolved into a thriving wetland landscape shaped by natural processes.

Where the North Brook was once confined to a straightened, artificial channel, it has now been reconnected to its historic course across the valley floor. Combined with improvements such as footbridges and added river gravels, the site is now more accessible, more resilient, and far richer for wildlife.

Why restoration was needed

Historically, the North Brook at Coundon Wedge had been heavily modified. Prior to the restoration work the brook was straightened, raised, and disconnected from its natural floodplain. This altered channel restricted natural river processes, limited habitat diversity, and created barriers for wildlife movement.

Water was forced into a single, perched channel, while the original river course (deemed a "paleo channel") remained partially visible in the landscape, holding water during wetter periods but no longer functioning as intended. Culverts and a weir further disrupted flow, sediment movement, and fish passage.

Despite these changes, the underlying landscape still held the blueprint of a healthy river system that could be restored by working with natural processes rather than against them.

What has changed

A return to the river’s natural path
Through Stage Zero restoration, the North Brook has been redirected back into its historic "paleo" channel. The term "stage zero" refers to the natural state a habitat should be in prior to any human intervention. Instead of being confined to an inaccessible edge of the field, the water now spreads more naturally across the valley floor, reconnecting with its floodplain and forming a more dynamic wetland system.

This allows the landscape to act more like a sponge, holding water during high flows and releasing it slowly, helping to reduce flood risk downstream.

A developing wetland mosaic
The restored channel now interacts with surrounding low-lying areas, creating a network of wet habitats that support a wide range of species. Water filtering through wetland vegetation also helps to improve overall water quality.

New footbridges maintain public access
New footbridges have now been installed across the restored channel, making it easier for visitors to explore the site and experience the changing landscape without disturbing sensitive habitats. These crossings help maintain access while supporting the long-term protection of the area.

Gravel enhancements for river health
Additional gravels have recently been introduced into sections of the channel. These help to stabilise the riverbed, preventing erosion into underlying clay, while also creating valuable habitat for fish and invertebrates.

These gravels improve oxygenation and provide ideal conditions for spawning and aquatic life, supporting the continued development of a healthy river ecosystem.

Benefits for wildlife

The restoration at Coundon Wedge has created a more diverse and resilient environment, supporting:

• Fish moving more freely through the channel
• Invertebrates thriving in gravel and wetland habitats (Recordings of Stonefly show high ecological health of the river)
• Birds using the wetland areas for feeding and nesting (Snipe and little egrets have since been spotted using the site)
• Amphibians and mammals benefiting from improved water and habitat connectivity

As the site continues to evolve, it is expected to attract an even wider range of species, strengthening its role as a key wildlife site within Coventry.

Benefits for people

Coundon Wedge remains a much-loved green space, and the restoration enhances its value for visitors.

The new footbridges maintain access and allow people to experience the restored landscape more closely, while the evolving wetland offers a constantly changing natural environment to explore.

The work also supports the long-term sustainability of the site, helping to manage water more naturally while maintaining its role as an important space for recreation, learning, and connection with nature.

Supported by the community

The restoration has been shaped by strong local support, including input from the Allesley and Coundon Wedge Conservation Society and the wider community. Consultation feedback showed clear backing for restoring the brook and improving habitats, reflecting a shared ambition to protect and enhance this important site.

Looking ahead

Coundon Wedge is now in an exciting phase where natural processes take the lead. Seasonal changes, vegetation growth, and shifting water levels will continue to shape the landscape over time.

The additions of footbridges and gravel enhancements build on the initial restoration, ensuring the site remains both accessible and ecologically robust.

What has been created here is  a living system that will continue to adapt, support wildlife, and provide value to the community for years to come.
