Do you need a beaver survey in Cornwall?

Beavers are now an increasingly important ecological consideration for development in Cornwall, particularly where proposed works affect rivers, streams, wetlands and connected riparian habitats.

A beaver survey may be required where your Cornwall development involves:

  • Works within or alongside a river or stream

  • Riverbank excavation or engineering

  • Bridge, culvert or watercourse crossing works

  • Drainage or flood management works

  • Clearance of bankside trees or vegetation

  • Development affecting wetlands or connected waterbodies

  • Infrastructure close to suitable riparian habitat

  • Changes to water levels, drainage or hydrology

  • Preliminary Ecological Appraisal identifying potential beaver habitat or activity

The presence of a watercourse does not automatically mean a beaver survey is necessary. Survey requirements should be based on habitat suitability, available records, evidence of activity and the potential impacts of the proposed works.

Beaver Surveys & Cornwall Planning

Depending on the location of your project, planning applications will generally be determined by Cornwall Council, with separate planning arrangements applying within the Council of the Isles of Scilly.

Beaver considerations are particularly relevant to Cornwall because wild beaver activity is now established within the county. The Par and Fowey catchment is the focus of a licensed wild beaver release programme, while beaver activity has also been recorded within the Tamar catchment.

Development affecting suitable watercourses, wetlands or connected riparian habitat may therefore require appropriate ecological assessment where there is potential for beavers or their protected breeding and resting sites to be affected.

Other major Cornish river systems and their tributaries include the River Camel, River Fal, River Hayle, River Lynher and River Looe, alongside an extensive network of smaller rivers, streams and wetlands capable of providing freshwater and riparian habitat.

Surveys can be conducted across Cornwall, covering major towns, suburban fringe areas, and surrounding villages such as Wadebridge, Redruth, and Saltash.

Compliance & Legislation

Conservation of Habitats and Species Regulations 2017
Eurasian beavers are a European Protected Species. The legislation protects beavers from deliberate killing, injury, capture and disturbance, and protects their breeding sites and resting places from damage or destruction.

Wildlife and Countryside Act 1981 
Provides additional legal protection relevant to beavers, including controls relating to certain methods of capture and their release into the wild.

For development in Cornwall, proposed works that could affect beavers, their breeding or resting sites, or important supporting habitat may require appropriate ecological assessment, mitigation and, in some circumstances, a Natural England licence.

ProHort provides proportionate, evidence led advice to establish the ecological requirements of your project and help support a compliant route through planning.

Local Beaver Insight: Cornwall

Cornwall has become particularly significant in the return of beavers to the English landscape. The Cornwall Beaver Project began with beavers in a five acre enclosed site alongside Nankilly Water near Ladock, where their effects on water flow, wetland creation and biodiversity have been studied. More recently, Cornwall has moved into a new phase of beaver recovery. Following approval from Natural England, the county's first fully licensed wild beaver release took place in February 2026, with animals released as part of a long term project within the Par and Fowey river catchment. Wild beavers are also established within the Tamar catchment. For planning and development, this means beaver considerations are becoming increasingly relevant to projects affecting suitable freshwater and riparian habitat within Cornwall. A site does not need to be immediately adjacent to a known beaver location to warrant consideration. Habitat connectivity, catchment context, field signs and the nature of the proposed works all contribute to determining whether further assessment is necessary.

How Beaver assessments work

Our specialist ecology team carries out a Beaver Survey to identify signs of beaver activity, including feeding signs, tracks, burrows, lodges, dams and important habitat.

You receive a clear, LPA ready report assessing potential impacts and setting out any required mitigation, monitoring or licensing considerations, helping your project stay on schedule and compliant.

FAQ - Beaver Surveys in Cornwall

When is a beaver survey required for a development in Cornwall?

A survey may be required where proposed works could affect beavers, their breeding or resting sites, or suitable freshwater habitat. Particular consideration should be given to sites close to rivers, streams, wetlands and riparian habitats where beaver activity is known, suspected or identified during a Preliminary Ecological Appraisal.

Yes. Wild beavers are now present in Cornwall. A licensed wild release programme is underway within the Par and Fowey catchment, and beaver activity is also established within the Tamar catchment.

This makes consideration of beavers increasingly relevant to planning and development within suitable freshwater habitats across the county.

Cornwall contains an extensive network of rivers, streams and wetlands. Major river systems include the Fowey, Tamar, Camel, Fal, Hayle, Lynher and Looe, together with the Par and numerous smaller tributaries and connected watercourses.

Whether a particular site requires a beaver survey depends on habitat suitability, available records and the potential impacts of the proposed development rather than simply its proximity to a named river.

Not automatically. Being next to a river does not itself trigger a survey. The ecologist should consider the suitability of the habitat, evidence and records of beaver activity, connectivity with other suitable habitat and how the proposed works could affect the watercourse.

Potentially. The Par and Fowey catchment is particularly relevant because it is the focus of Cornwall’s licensed wild beaver release programme.

Development affecting suitable watercourses and connected habitat within the catchment should therefore consider the potential for beavers at an appropriate stage of ecological assessment.

What signs of beavers will an ecologist look for?

Our ecologists look for evidence including gnawed or felled trees, feeding remains, footprints, tracks, slides, scent mounds, pathways, burrows, lodges and dams.

We also assess the surrounding habitat to understand how beavers may be moving through and using the watercourse.

Yes. Works that modify riverbanks, culverts, drainage infrastructure, water levels or hydrology can potentially affect beavers and their habitat.

The need for assessment depends on the location of the works, habitat present and evidence of beaver activity.

Not necessarily. The presence of beavers does not automatically prevent development.

Our ecologists assess how the proposed works could affect the animals and any protected breeding or resting sites. Where impacts are identified, avoidance should be considered first, followed by proportionate mitigation or licensing where necessary.

Yes. Eurasian beavers are a European Protected Species under the Conservation of Habitats and Species Regulations 2017.

Their legal protection means proposed works that could disturb beavers or damage or destroy protected breeding and resting sites require appropriate ecological consideration.

You receive a clear, LPA ready ecological report setting out survey findings, identified activity and habitat features, potential development impacts and any necessary avoidance, mitigation, monitoring or licensing considerations.

Our recommendations focus on identifying the minimum necessary ecological work required to support your planning application and keep the project progressing.
