A River of National Importance
Flowing through Dorset, Somerset, and Devon, the River Axe is one of the UK’s most significant river systems—recognised as both a Special Area of Conservation (SAC) and a Site of Special Scientific Interest (SSSI).
Despite centuries of human modification, the Axe still retains important ecological features and habitats. It supports an exceptional range of aquatic and marginal plants, as well as protected species including Atlantic salmon, bullhead, otter, and medicinal leech. The catchment spans over 307 km², with 59 km of major rivers and tributaries.
A System in Decline
For over 40 years, the River Axe has been in unfavourable condition. It currently fails Water Framework Directive standards due to:
- Chronic phosphate enrichment
- Severe sediment build-up from soil erosion
- Algal blooms and low water clarity
- Disconnected floodplains and unstable channels
To meet the SAC standard, average phosphorus concentrations must be reduced by at least 50%. Without intervention, the system risks irreversible damage.
A River Worth Saving
The River Axe shares its name with the Exe and Usk—from the Celtic word meaning “abounding in fish.” That name reflects the river’s natural potential—and our collective ambition.
While its condition has declined, this is still a living river: otters, rare plants, and aquatic invertebrates remain. Our work is designed to support their recovery, restore natural function, and improve water quality for the benefit of all.
Our River and Riparian Zone Restoration Plan
Our plan focuses on repairing the river’s physical structure, restoring natural hydrology, and rebuilding riparian habitats critical to the river’s long-term health.
In the submitted 20-year Land Management Plan, we set out a detailed programme of works in the main channel and the riparian management zone (RMZ), including:
In-river restoration
- 20 km of channel restoration, including bed raising, gravel addition, and re-meandering
- Introduction of large woody material to roughen flows, create habitat, and slow erosion
- Stabilisation of eroding banks using live willow stakes and riparian planting
- Removal of artificial structures that impede natural sediment transport and fish movement
- Restored channel complexity to support diverse flow types, riffles, pools, and aquatic cover
Riparian management zones (RMZ)
- Creation and management of 172 hectares of RMZ to buffer the river from runoff and restore habitat connectivity
- Establishment of riparian woodlands, wet grassland, and species-rich margins
- Invasive species control, including 2,578 m of Himalayan balsam removal
- Exclusion of livestock from sensitive riparian areas to reduce poaching and bank damage
- Use of coppice, brash, and local materials to stabilise banks and enhance habitat structure
Hydrological reconnection
- Restoration of floodplain connectivity in targeted areas
- Creation of backwaters, scrapes, and paleochannels to support water retention and refuge habitats
- Reduction of channel incision and increase in natural flood storage capacity
These interventions are designed not as isolated actions, but as part of a strategic catchment-scale plan to restore the River Axe SAC to a naturally functioning, ecologically rich state.
Every intervention in the project is focused on one goal:
to restore the River Axe SAC to favourable condition, now and for the future.
