Ecosystem restoration

Saltmarsh Project

Thirteen partners and six artists working for over three years to survey, restore and communicate saltmarsh life along the Dart Estuary. Sharing river knowledge, finding paths to understanding and action for communities of interest along the way.

Helping to protect this vital ecosystem and carbon store

You might be surprised to hear that saltmarshes absorb and lock away more carbon than equivalent areas of any type of forest. And yet more than 85% of England’s saltmarsh has been lost in recent centuries to development and changing land use, and more is at risk through rising sea levels and climate change.

Muddy, grey and brown in the winter, the Dart's saltmarshes often go unnoticed. But they are fragile and sensitive communities full of flowering plants and creatures despite being regularly flooded by the saltwater tides. Saltmarsh plants grow along the upper shorelines of the estuary—a surprisingly harsh habitat. They absorb tidal and wave energy and help prevent flooding. They regulate water quality by absorbing excess phosphates and nitrates in river water as well as salt from the incoming tides. They are important places for wading birds to breed, spend the winter and stop off during migration. Saltmarshes are essential.

Every part of a river, like every part of our body, has a role to play in keeping us healthy. And as with the human body, what we put into it finds its way downstream, washes up on shore and then out to the sea.

Ecological restoration in action

Ecological restoration in action

The Saltmarsh Project is ongoing. Restoration techniques are being trialled along a string of saltmarshes on the Dart from Longmarsh to Sharpham Point. The aim is twofold: to help saltmarshes maintain their own natural processes and ecological function, and to produce a range of ways for nearby communities to appreciate their value. Volunteers have helped make bundles of locally coppiced willow and hazel, tied together with sisal and staked into the mud across gullies. This slows the flow of the tidal waters, helping to build up sediment over time, establishing the conditions that support the saltmarshes to flourish. The Project includes construction of a new boardwalk at Longmarsh and the repair of a section of Napoleonic stone wall at Sharpham. The work is funded by the Environment Agency.

Art meets ecology

Art meets ecology

A unique aspect of this conservation work is its intentional integration of art and science. The Project invited a diverse group of local artists to create interpretive works inspired by their personal experiences of the saltmarshes. These include Ivan Grieve's mixed-media explorations, Christian de Sousa's soundscapes, and Clare Parker's tidal dance films Flux and Suspire. Artists and ecologists, paired together, share their roles and accomplishments at celebratory events hosted by BLC.

Community engagement and future vision

Community engagement and future vision

The Project has involved local communities through talks, boat trips, events, artist-led invitations and volunteer opportunities. An early poll of 84 Dart residents indicated strong support for actions such as interpretive signage (78.5%), media resources (72.5%), and guided marsh encounters (71.2%), which the team is successfully delivering.

Looking ahead, a development pathway for restoring ecosystems is via the Estuaries Management Plan: assessing other saltmarshes in the bioregion (Yealm, Avon, Kingsbridge/Salcombe, Erme), on-going monitoring on the Dart, trialling additional restoration efforts. BLC is focusing on a strategic plan based on a wider estuary context to include multiple habitats and communities, expanding the Project framing; ‘Develop Models’, 'Restore Ecosystems’ and ‘Link in Communities’.

Described as 'what happens when BLC steps in', BLC's role in The Saltmarsh Project demonstrates what bioregioning looks like on the ground: ecologically and socially important, inviting, visible, ambitious, with long-term commitment.
