For me, one of the standout talks at the BTO’s Cudyll Cymru Convention earlier this year covered the proposed reintroduction of white-tailed eagles in Wales. The talk, by Dr Sophie-Lee Williams, outlined the obstacles and barriers her organisation face when looking to reintroduce this majestic raptor.

Rewilding continues to be one of the most inspiring concepts in modern conservation. The vision of restoring degraded ecosystems by reintroducing lost native species captures the public imagination and offers a powerful antidote to biodiversity loss. Yet behind the headlines of majestic returns sometimes lies a far more nuanced reality, a point outlined in Dr William’s presentation.

What is often overlooked is that when missing species are reintroduced to areas their ancestors once inhabited, they do not return to the same type of wilderness. They often return to a countryside actively managed and utilised by humans. This interaction can often trigger friction between conservationists and local stakeholders.

The debate surrounding the white-tailed eagle, Britain’s largest bird of prey, with a 2.4-meter wingspan, is one of the clearest examples of this divide. Lost from the UK in the early 20th century due to severe persecution, the eagle has made a remarkable comeback through reintroduction schemes that began in Scotland in 1975, followed by projects on the Isle of Wight and Exmoor. While wildlife enthusiasts celebrate the return of these airborne giants, some upland sheep farmers view them with anxiety.

Conservationists see the return of these apex predators, who are also general scavengers and good at removing carrion from the landscape, as an income generator by boosting eco-tourism. However, on the other side of the argument, farmers cite lamb predation, stress during spring lambing season, and uncompensated losses that are hard for smallholders to absorb as reasons to resist reintroductions.

For an upland sheep farmer operating on thin profit margins, losing even a small percentage of stock to an eagle can significantly hit their livelihood. This tension has led to low support among farming groups in proposed release areas, proving that public enthusiasm for rewilding drops significantly when personal livelihoods are directly on the line.

Friction isn’t limited to deliberate reintroductions; natural range expansions and recovery success stories can also create challenges. The osprey has made an extraordinary recovery across Britain over several decades. As breeding pairs expand from Scottish strongholds into England and Wales, with nesting and foraging sites establishing along river corridors, their success brings unexpected friction to water bodies across the Midlands.

In my own area in Shropshire, where managed coarse and trout fisheries are popular, a visiting osprey presents a distinct commercial challenge. But ospreys enjoy strict legal protections under the Wildlife and Countryside Act; options for fishery owners are limited to non-lethal deterrents like visual scaring devices or overhead stringing, which can be expensive and impractical over large bodies of water.

It’s not just wild places and countryside locations with fisheries that can have problems with certain species. The problem reaches into residential gardens with the grey heron. This species is native, often seen on our waterways, and was never reintroduced. Yet many suburban gardeners (my father included) who spent years cultivating a garden pond stocked with prized koi or goldfish often complain about the local heron. A single early-morning visit from a heron can wipe out hundreds or even thousands of pounds worth of fish in minutes. The conflict highlights a fundamental rule of wildlife interaction: birds do not distinguish between wild habitats and human investments. To a heron, a garden pond is simply a clear, shallow pool with zero tree cover and easy targets.

The tension surrounding white-tailed eagles, ospreys, and even herons demonstrates that rewilding cannot succeed purely on ecological grounds. For species recovery to work in the modern world, conservationists must account for human impacts. Reintroduction proposals should include clear management, a plan for rapid compensation schemes, and possibly mitigation strategies for land managers before release.

In an ideal world, funding should support practical deterrence measures for commercial fisheries and livestock owners. These could include protective netting, non-lethal deterrents, and guarded lambing enclosures. But as we know, sadly, we don’t live in an ideal world. Local land managers, farmers, and business owners also need to be involved as key stakeholders at the start of any wildlife restoration project.

True conservation success isn’t just about bringing a species back—it’s about building a landscape where both wildlife and working communities can sustainably coexist.
