2021 will be a record year for beaver releases

  • The Wildlife Trusts are releasing a record number of beavers in 2021 – twenty years after bringing the first ever beavers back to Britain.
  • Around 20 beavers will be released this year including to a project in Wales. The first of the year’s releases took place in Dorset this week.

Plans developed by Wildlife Trusts of Dorset, Derbyshire, Hampshire and the Isle of Wight, Nottinghamshire and Montgomeryshire will see new beaver families moving into these counties for the first time. The Wildlife Trusts have been at the forefront of beaver reintroduction and projects in Britain ever since Kent Wildlife Trust released the first pair into a fenced area of fenland in 2001, followed by the Scottish Beaver Trial in 2009.

These industrious herbivores are native to mainland Britain but were hunted to extinction in the 16th century by people who wanted their fur, meat and and scent glands. The loss of beavers led to the loss of the mosaic of lakes, meres, mires, tarns and boggy places that they were instrumental in creating. Their ability to restore and maintain important wetland habitats is why reintroducing this species is so important.

Craig Bennett, chief executive of The Wildlife Trusts says:
“Beavers are a fantastic keystone species that have a hugely important role to play in restoring nature to Britain. It’s brilliant to see Wildlife Trusts across the UK ensuring a better future for wetlands and for a wealth of other wildlife by bringing back beavers whose engineering capabilities inject new life into wild places. The benefits for people are clear – beavers help stop flooding downstream, filter out impurities and they create new homes for otters, water voles and kingfishers. What’s more, people love seeing them and their presence boosts tourism in the countryside.

“We live in one of the most nature-depleted countries in the world which is why we have a big ambition to protect 30% of land and sea for nature by 2030. We’re calling on the government to come up with an ambitious strategy to enable beavers to return to help tackle the climate crisis and improve wetlands for wildlife.”

Five years of research by Devon Wildlife Trust shows that beavers bring a valuable range of improvements for people and wildlife:

  • They create a wonderful range of wetland habitats that provide homes for other wildlife and greatly enhance conditions for nature to thrive
  • The channels, dams and wetlands that beavers engineer hold back water and release it more slowly after heavy rain, helping to reduce the risk of flooding
  • Their activities prevent soil being washed away after rainfall – their dams filter water, cleaning it and reducing pollution downstream

Devon Wildlife Trust and its partners in the River Otter Beaver Trial have developed extensive experience supporting people to live alongside these industrious creatures once again. DWT led a locally-agreed management strategy which has proved crucial in enabling local communities, volunteers and landowners to work together to maximise the benefits beavers bring, and successfully manage localised problems which can occur.

This year, individual Wildlife Trusts are raising funds to bring the beavers back, making their new homes ready and carrying out the checks they need. Future releases are expected to trap, vet-check and move beavers from a substantial population in Scotland.

New Wildlife Trust beaver releases for 2021 – for the first time in these counties:

Dorset Wildlife Trust
On Monday 8th February two beavers were released at an enclosed site in Dorset following feasibility studies and careful monitoring to look at the difference they could make to an enclosed wetland. Following several years of preparation, including installing a specialist fence to enclose the site and recording baseline data with experts from University of Exeter and Wessex Water, the pair of Eurasian beavers (Castor fiber), an adult male and female, are now settling in. (See separate images in the dropbox further below.)

Derbyshire Wildlife Trust
Two beaver families and their kits will be released this year into a 12 hectare enclosed area of Willington Wetlands reserve in the Trent valley following a very successful fundraising campaign and feasibility studies. Beavers will help to increase the water storage capacity of the nature reserve. The site is being made ready for beavers to be rehomed from a site in Scotland later this year.

Hampshire and Isle of Wight Wildlife Trust
Subject to a successful licence application, the Trust plans to release beavers on the Isle of Wight for the first time. The results from the Trust’s feasibility research on their reserves in the Eastern Yar were very positive and show the habitat would be well suited to beavers – it is hoped that they can be officially released into an open area, rather than fenced enclosures. The Trust is looking forward to discussions with landowners and local communities about a potential beaver release over the course of the year.

Nottinghamshire Wildlife Trust
The Trust plans to reintroduce at least four beavers this summer into a huge enclosure in the spectacular Idle Valley Nature Reserve in North Nottinghamshire. This will be part of a project to harness the power of natural processes to transform what is already one of the best inland nature-watching places in the region.

Montgomeryshire Wildlife Trust
The Welsh Beaver Project (led by North Wales Wildlife Trust on behalf of the five Wildlife Trusts in Wales) has been assisting Montgomeryshire Wildlife Trust with their plans to release a pair beavers into an enclosure at their Cors Dyfi Nature Reserve, near Machynlleth. It will be the first officially licenced release of beavers in Wales. The beavers will play a vital role in managing invasive willow and scrub which threatens wetland areas of this lowland bog. An application with supporting information has been submitted to Natural Resources Wales for their decision and they hope to see beavers at Cors Dyfi Nature Reserve this spring.

Urban beavers – new for 2022!
Shropshire Wildlife Trust have identified a 12 hectare site in central Shrewsbury where a pair of beavers will be released in an enclosure in 2022. The beavers will be replacing grazing cattle to prevent trees and scrub for invading the wetland. The site is surrounded by housing estates and a school, so there will be plenty of opportunity for local people to be involved.

Recent beaver releases by The Wildlife Trusts
In November 2020 Cheshire Wildlife Trust reintroduced a pair of beavers at Hatch Mere Lake. The couple settled into their new 4.5-hectare enclosure as part of a five year project. The Trust will monitor the changes these eco-system engineers make, checking the quality of the water and the effects on wildlife including breeding birds, bats, aquatic invertebrates and the rare plants and mosses.

Also in 2020, Cumbria Wildlife Trust was involved in the reintroduction of two beavers to an enclosure at the Lowther Estate in the Lake District. This film shows the amazing work that the pair have done in the past month to slow the flow of water and improve the habitat for other wildlife.

Additionally, in the last twenty years The Wildlife Trusts have been involved in beaver reintroductions and projects in Kent, Argyll, Devon, Cornwall and Sussex.

The Wildlife Trusts expect Defra to release a public consultation on a beaver strategy for England shortly, which will look in more detail at the management of beavers in the wild and future reintroductions. The Wildlife Trusts want to see clear support for beaver reintroductions into catchments across the country. We are calling on the government to:

  • Clarify their legal status in England. Beavers became a legally protected native species in Scotland in 2019.
  • Agree an ambitious strategic approach to enable their return to help tackle the climate crisis and improve wetlands for wildlife.
  • Make funding available for landowners and local beaver management groups to help reintegrate beaver into our countryside.
