Mitigate Beaver Impacts

Protect against potential beaver burrowing, damming & foraging

Beavers significantly modify landscapes. As a result beaver activities can result in conflicts with some riparian land use by humans. Such conflicts predominantly result from beavers damming watercourses, burrowing into the banks of water bodies and foraging for food including felling trees.

Given that beavers do not like to move far from water, the majority of their activities take place in the riparian zone (i.e. the area running adjacent to a river or stream) and are recorded within a maximum distance of thirty metres (thirty-three yards) from the edge of a freshwater body. For this reason, it is important to leave space, as far as possible, for beavers along the water’s edge and restore riparian habitat.  However as the table below shows, there are a number of interventions humans can make to reduce the impact of beaver damming, burrowing and foraging where this does occur.

 

Type of activity

Potential Risks

Solutions

Potential Benefits

Foraging

Loss of crops

Loss of ornamental vegetation

Loss of valued trees

Temporary / deterrent fencing

Permanent / deterrent fencing

Planting less palatable species

Tree guards

Anti-game / sand paint

Planting sacrificial buffer strip

Livestock & deer grazing management

Create more wetlands, increased bank resilience, restoration of natural processes and naturalised riparian zone

Damming

Loss of crops

Loss of trees

Damage to infrastructure

Downstream effects of dam failures

Dam removal

Dam notching

Flow devices

Beaver dam analogues

Culvert protection

Moving land activites to higher ground and renaturalising floodplain.

Use oversized culverts / larger bridge arches

Create more wetlands, increased bank resilience, restoration of natural processes and naturalised riparian zone

Burrowing

Bank erosion

Undermining of infrastructure

Riparian buffer zone

Greenbank protection / reinforcement

Livestock exclusion / grazing regimes

Mesh fencing

Metal piling

Hardcore infrastructure / stone facing

Create more wetlands, increased bank resilience, restoration of natural processes and naturalised riparian zone

Some of the mitigation solutions listed above may require securing, in advance, a licence and permits from the relevant regulatory authorities and landowner permissions. Please visit the relevant pages below to find out more.

Beaver Foraging

Beavers fell trees for food and construction materials. Some tree-felling can be undesirable and occasionally hazardous. Protecting a tree from beaver browsing can be simple, inexpensive and quick. 

Beaver Damming

Beavers build dams for protection from predators. Sometimes these dams can cause localised flooding, affect infrastructure and may hinder passage of migratory fish in some specific circumstances. There are a number of management techniques which can be employed to resolve this.

Beaver Burrowing

Where the banks of a watercourse allow it, beavers will excavate burrows instead of building lodges. Burrowing activity can cause bank erosion and undermine infrastructure on some soil types.
