Beavers at Little Sea, Studland

Two pairs of beavers were released into the wild at Little Sea, Studland, in March 2025, under licence from the government. It was the first licence of its kind to be issued in England – all the previous ones have been for beavers in enclosures.

These animals joined the beaver family that appeared in the lake in early 2024 (whether by natural dispersal or an illegal release), and our aim is now to establish a viable population. (See project updates below.) 

Why restore beavers to Purbeck?

Previously beavers were an important part of the natural ecosystem but became extinct across the UK in the 16th century due to hunting for their fur, meat and scent glands. Restoring lost species to our landscapes is an important part of our work to reverse the declines in nature.

Beaver activity can increase biodiversity by providing habitats for a wide range of species including fish, amphibians, mammals, water-loving plants and insects.

The habitat beavers need

Beavers need areas of deep, still or slow flowing fresh water to feel safe. Although Little Sea originated as a landlocked body of seawater, it has been replenished by fresh water draining off the heathland and is now classed as fresh water. Surrounded by dense woodland, it is thought to be a highly suitable habitat for beavers. 

How beavers will benefit Little Sea and beyond 

Beavers create their own wetlands and bring wildlife back to the landscape as they do so. There is evidence that a range of species (aquatic plants, amphibians, aquatic invertebrates) hugely benefit when beavers are present in a landscape. 

Little Sea is surrounded by a dense wet woodland of willow. As the beavers fell trees, they will create glades and open patches. This allows light to penetrate the canopy, attracting myriad wildlife such as dragonflies, bees, butterflies, birds and wildflowers.  The beaver activity doesn't kill the trees - as with traditional coppicing, the trees soon sprout new shoots, creating a much more dynamic woodland with trees of all ages.  

If the beaver introductions at Little Sea are successful, the aim is that they will eventually spread onto the Purbeck Heaths. They will create beaver wetlands that help retain and purify water resources and slow the flow in our rivers, reducing the risk of flooding and drought. These wetlands are also one of the best ways to capture carbon. 

A carefully managed approach

Across the UK beavers are gradually being brought back into the countryside as part of a managed approach. Beavers have been successfully reintroduced into enclosures at several National Trust sites in recent years, including Holnicote in Somerset where several kits have been born.    

We are part of the Dorset Beaver Management Group which consists of trained people who can provide expert advice, information and support, particularly to communities and landowners who are living alongside beavers.

New kits - and wet wetland despite the drought!

There is good news from Little Sea, where our resident beavers have successfully produced kits once again this year. Two young kits have recently been spotted on trail cameras, bringing the Little Sea family group to seven animals in total.

The new arrivals are easy to identify thanks to their small size and distinctive buoyancy. When swimming, young kits bob back to the surface like corks after diving, making them stand out from the adults. The family now consists of two adults, one kit from 2024, two kits from 2025 and two new kits from 2026.

Visitors hoping to spot the beavers have the best chance from the Rees Cox Hide at dawn or dusk, although sightings are also occasionally reported from the Triangular Hide at the north of Little Sea. Anyone who sees beavers is encouraged to contribute to monitoring efforts using the QR codes displayed in the hides.

New beaver wetland stays wet in drought

The adventurous beaver pair that established a new wetland within woodland in Studland continue their eco-engineering activities. Despite recent dry conditions, their network of dams continues to hold water successfully, creating valuable wetland habitat.

A recent drone survey is helping monitor changes across the site, including tree cover and open water. The wetland is already attracting a wide range of wildlife, with specialist volunteers recording seven species of dragonfly and damselfly this summer.

Although this beaver pair was observed mating earlier in the year, no kits have yet been seen. As both animals are still relatively young, there remains plenty of time for them to start a family in the future.

Innovative monitoring techniques

Monitoring beavers is becoming increasingly sophisticated. While some animals can be identified by distinctive features, such as scars or marks on their tails, others are much harder to tell apart.

The team has begun trialling a new identification method that uses unique tail markings and scars to distinguish individuals, following techniques developed by other beaver conservation teams. This approach could improve monitoring accuracy while avoiding more invasive methods.

It’s a wrap!

The project also continues to track signs of beaver activity across Studland. Alongside their preferred willow and birch, beavers have recently been observed feeding on oak trees.

These observations provide valuable insights into how beavers shape their environment and help us develop management techniques. Rangers are already trialling measures such as wrapping selected trees to reduce beaver damage where protection is required, such as for veteran trees or those with sentimental value.

Otters continue to flourish

Otters continue to thrive at Little Sea and surrounding wetlands, co-existing happily with the beavers. Recent footage has captured otters fishing in Little Sea, Eastern Lake and the newer beaver-created wetland, while pups have been recorded in all three locations
