Wildlife Restoration in the UK: A Moral Imperative to Reintroduce Endangered Species

Conservationists leading wildlife restoration projects across the UK say there is a clear moral imperative to reintroduce endangered species into their natural habitats. From river ecosystems to open grasslands and coastal skies, species reintroduction is transforming British landscapes while helping to reverse decades of environmental decline.

Across the South West of England, pioneering projects are restoring biodiversity, strengthening ecosystems, and delivering long-term environmental benefits for both wildlife and people.

Great Bustard Reintroduction on Salisbury Plain

One of the UK’s most ambitious species recovery programmes is led by the Great Bustard Group (GBG).

“It would be wrong of me to depart this world, whenever that may be, with fewer species or less wildlife around me than when I joined this earth,” said executive officer of GBG, David Waters.

The Great Bustard was once a familiar sight in British skies until the mid-1800s. Intensive trophy hunting and large-scale agricultural change led to its extinction in the UK. Today, the species remains at risk of global extinction — the only British bird to hold this status.

Since 2004, conservationists have released hundreds of Great Bustards onto Salisbury Plain in Wiltshire. There are now approximately 50 birds established across south Wiltshire, with successful breeding recorded every year since 2009.

Salisbury Plain offers ideal habitat conditions, providing open grassland and low human disturbance — essential for the long-term survival of this iconic bird.

“They did well in farmlands for hundreds and hundreds of years, but it is the big, wide, open area they like – what I call big sky country,” Waters said.

“Also, within Wiltshire, [the bustard] has always been the symbol of the county, on our coat of arms, the main feature of the Wiltshire flag and the county badge of many organisations including girl guides and army cadets.

“So there’s a cultural restoration as well as an extra tick on the biodiversity sheet.”

Restoring Ecosystems Through Species Reintroduction

According to conservation leaders at the Somerset Wildlife Trust, species reintroduction is about more than saving individual animals — it is about repairing damaged ecosystems.

Simon Clarke, head of recovery at Somerset Wildlife Trust, said: “This enables improvements in biodiversity for a whole range of flora and fauna – it’s about restoring balance,” he said.

“The wider ecological benefits that these species bring is that they will be part of the natural trophic system and have a unique role, providing a function, perhaps a predator which will control numbers of other species that may be detrimental.”

Decades of habitat loss, pollution and human activity have weakened natural systems. Reintroducing key species helps to restore ecological balance, rebuild food chains and increase biodiversity.

Crucially, successful wildlife restoration depends on collaboration with farmers, landowners and local communities. Addressing concerns, providing ongoing monitoring and ensuring transparency are essential parts of responsible conservation.

The Return of the Large Blue Butterfly

A powerful example of successful reintroduction is the large blue butterfly. Declared extinct in the UK in 1979, it has since made a remarkable comeback thanks to careful habitat management and species recovery efforts led by conservation organisations including Somerset Wildlife Trust.

Today, the large blue is once again thriving in carefully managed landscapes — proof that extinction can be reversed with science-led conservation and community support.

Beaver Reintroduction and Natural Flood Prevention

Beavers are natural ecosystem engineers. Their dams slow water flow, improve water quality and reduce downstream flood risk.

Recently, beavers were released into the wild in Somerset for the first time in modern history — a major milestone for nature recovery in the region.

National Trust project manager Ben Eardley said: “These ecosystem engineers play a vital role in helping slowing water flow, creating and holding wetland habitats, reducing erosion [and] improving water quality.

“So that means as well as delivering for nature, those nature-based solutions are really delivering for people and helping to reduce downstream flood risk.”

Projects like these demonstrate how wildlife restoration delivers measurable environmental benefits, including:

• Improved water quality
• Natural flood prevention
• Increased biodiversity
• Healthier wetlands

Organisations such as the National Trust continue to work with landowners to monitor impacts and manage potential risks.

“Part of it is having volunteers and rangers who are skilled, identifying activity and dealing with it accordingly,” he said.

White-Tailed Eagles Return to Southern England

Britain’s largest bird of prey, the white-tailed eagle, is also making a comeback.

Since 2019, the Roy Dennis Wildlife Foundation and Forestry England have been reintroducing white-tailed eagles to southern England. In 2023, a pair successfully bred for the first time — a landmark achievement for the programme.

Several of these majestic birds now regularly visit Exmoor, and further releases of 12-week-old chicks are planned, strengthening the population and restoring a missing apex predator to the ecosystem.

“By choosing a big, obvious bird, we’ve found so many ordinary people – not all birdwatchers or those going to reserves – can see the eagles flying over different parts of the south and it’s proved we can restore nature,” said Roy Dennis OBE.

“There’s been a tremendous response from the public and [that] has given them hope for the future,” the conservationist added.

The Wider Benefits of Wildlife Conservation

Conservationists agree that reintroducing species into the wild benefits both nature and people. Thriving ecosystems contribute to:

• Cleaner air and water
• Reduced flooding
• Increased climate resilience
• Stronger local biodiversity
• Nature-based tourism opportunities

Wildlife restoration projects require enormous commitment, scientific expertise and long-term perseverance — but the results are transformative.

Supporting UK Wildlife Restoration

Across Somerset, Wiltshire and beyond, conservation organisations are demonstrating that species recovery is possible. From Great Bustards on Salisbury Plain to white-tailed eagles over Exmoor, these projects represent hope for the future of British wildlife.

By supporting responsible rewilding and science-led conservation, we can help protect globally endangered species and restore the natural balance of our landscapes for generations to come.

At Natural World Fund, we believe restoring endangered species is central to rebuilding healthy, resilient ecosystems. From Great Bustards to white-tailed eagles and beavers, these reintroductions show how nature can recover with the right support. By backing science-led conservation and working with local communities, we help create landscapes where wildlife — and people — can thrive for generations to come.
