Cors Dyfi Beaver Enclosure

We have recently introduced a beaver family to a seven acre enclosure on Cors Dyfi Nature Reserve. They will provide a natural solution to the management of this recovering low-land peat bog.

Why Beavers?

Beavers were once widespread across the Wales, but due to over hunting by humans for their fur, meat and scent glands they became extinct after the Middle Ages in Wales and by the end of the 16th Century they were extinct from the rest of Britain.

Beavers are very special animals because they play a vital role in enriching biodiversity by restoring and managing river and wetland ecosystems. They are known as a ‘keystone species’ because their activities can benefit a wide range of other animals and plants that live in rivers and wetlands.


"Beavers are known as nature's engineers. They make changes to their habitats which create diverse wetlands for other species to thrive."

Our Beavers

The seven acre beaver enclosure at Cors Dyfi is home to a small family of beavers. We currently have three beavers, an adult female, an adult male and their year old son. The adult male beaver is very distinctive as he is a black morph individual, this means that instead of the regular brown colour for beavers, his fur is black.

Our beavers have come from Scotland under licence from NatureScot and have had full medical checks and health screening before they were moved to Cors Dyfi.

The Beaver Enclosure

The enclosure has a perimeter of around 700m and is built to the latest best practice specifications. The area contains three interlinked pools, a network of ditches and a mass of birch and willow scrub. There is plenty of food for the beaver family and lots of space for them to explore. The enclosure fencing will be monitored regularly in accordance with our licence from Natural Resources Wales.

The beavers will play an important role in helping us to manage the dense willow and birch scrub that is drying out the wetland. They will help us to ensuring the continued recovery of this damaged low land raised bog habitat.


Beaver Viewing

Once the beavers have settled in to their new home we hope to be offer some beaver viewing opportunities. Beavers are crepuscular, most active around dawn and dusk, so will generally not be seen during the day time. Animal welfare is our top priority so any viewing opportunities will carefully managed to minimise disturbance. We will of course bring you regular updates and images from our static cameras.
