IIt's easy to feel hopeless about the biodiversity crisis, but there are many reasons to be optimistic in the midst of despair and gloom. First, this year's study highlighted that conservation efforts are working.
Thanks to the hard work of dedicated organizations, scientists, committed private sector partners and thousands of dedicated local people, the UK is home to many biodiversity success stories. Beavers and eagles may dominate the headlines, but there's so much more out there, from impressive butterflies to tiny plants, from reimagined rivers to reborn mountain slopes.
Conservation is a complex undertaking, but new methods are emerging to conserve, improve and create new habitats, often bringing back or reintroducing species that haven't been seen for decades. . After a nudge, the ecosystem itself often does much of the heavy lifting. An inciting example can be the source of a massive counterattack. It's time to fight inertia and look to a brighter future for Britain's biodiversity. Let's pick out the field visits that are worth putting on your calendar for next year.
better blues
The plight of Britain's butterflies never makes the news, but it's not all about downward arrows and furrowed brows at lepidopterists. Dramatic revival of rare species including Purple Emperor (apatula iris) and Duke of Burgundy (Hama Alice Lucina), a noteworthy counter to the pessimistic narrative.
The most successful of all will almost certainly be the big blue (Fengaris ArionIt was declared extinct in 1979. Thanks to careful reintroduction plans since the early 1990s, its range now extends across south-west England. Underpinning it all was understanding its highly specialized life cycle. In addition to eating wild thyme, the big blue ant relies on a single heat-loving ant. Myrmica Sabretito bring the pupa into the nest. Special care is required to ensure that food plants appear at the right time and near the right ant colonies. Royal Entomological Society I've been doing it for decades.
More than 40 sites have been restored to large-scale habitat suitable for blues, starting with the Polden Hills in Somerset. Its scope has also been expanded with the help of evolution: Early after reintroduction, a new type arose that flew longer distances to find a suitable location.
One of the big blue houses that stands out is Daneway Banks in the Cotswolds. This success story has its roots in a chance encounter between Simcox and his colleague Jeremy Thomas with a farmer in a nearby pub. They volunteered to graze rare sheep on the property, maintaining the best vegetation for the species to thrive.
“As soon as we properly grazed the site, it took off completely,” Simcox says. “In a good year, it is said that 150,000 eggs are laid. It is now large enough to serve as a donor site for colonizing new areas.” Those new areas. Simcox is “sworn to secrecy” as to where it is located. Watch this space.

peel the willow
Forests are vitally important to ecosystems, and forest decline is felt more markedly in highlands, where many specialized species live. As a result of overgrazing, some of Scotland's native mountain trees have been pushed to the margins, but none has been more affected than the arctic alpine willow. By the early 1990s, these trees were nearly extinct, covering an area the size of a tennis court and clinging to the edges of steep cliffs.
How has their outlook changed? More than 30 years of joint efforts by conservationists and landowners have led to an inspiring comeback. Approximately 400,000 willow trees have been planted across the country using locally sourced seeds and cuttings, successfully ensuring thousands of hectares are thriving. This has practical benefits: strengthening tree lines can prevent flooding, avalanches and rockfalls at lower elevations. They also provide important habitat.
High-altitude willows support a diverse community of birds, mammals, and insects. In Scotland, 20 species of rare sawflies depend on sawflies, but continued restoration efforts will likely help ringwuzels (Thrush Torquatus), protected area red-listed birds, and the elusive highland nymph moth (Callisto Coffeela).
“Everything grows very slowly at high altitudes, so you have to have a long-term view and some patience, but I think that's really exciting,” says Sarah Watts. tracked progress For restoration of willow scrub.
Both willow and birch have returned to great effect in the Ben Lowers area, where fences exclude grazing animals, but Watts says fences present their own challenges. The next step for other projects is to sustainably manage free-roaming large mammals in parallel with continued tree regeneration, and early signs are promising.

orchid unit
There is no greater compliment to a species' recovery efforts than officially downgrading the severity of a threat to that species. That's exactly what conservation charities are proposing for orchids found in two areas on opposite coasts of England.
Unlike many other orchids, Fen Orchid (Liparis Roselli) Not an attention seeker. Because it is small and subtle, it has had limited success in the face of human landscape change. It also wasn't easy to find on the large property where surrounding plants tend to grow several feet tall. All of this together means that it has been classified as an endangered species since the UK's Conservation Red List was first created.
Now, that trend appears to be stopping. In the Norfolk Lakes region, numbers have gone from a few hundred to tens of thousands thanks to land management changes that reversed decades of habitat degradation and the reintroduction of expertly cultivated plants to new, suitable locations. It increased sharply in the second half. To do that, Tim Pankhurst says we need to “read everything that's ever been written” about the plant's habitat preferences. plant.
Plant Life now supports downgrading the orchid to 'Near Threatened' status, as visibility for the orchid is improving in the sand dunes of south Wales, but even if this happens, it will not be protected. The activity does not end. Landowners are working on effective management practices that pull species away from cliffs and increase broader biodiversity.
“Many species have been lost, including sandpipers and red-legged sandpipers that breed in inland marshes,” Pankhurst said. “People want them back, and one way to do that is to actually have more fen that is suitable for fen orchids, so that fen orchids can maintain their status as the flagship species of all things. will be established.”

soil solutions
Landscape change often starts with the soil. Director Richard Scott National Wildflower CenterFor most of his professional career, he has been deeply involved in things. He has helped build soil in the heart of northern cities, stripping away degraded topsoil and bringing colorful flowers to the wastelands. But he is a leading proponent of bolder interventions to spread human-centered land restoration more broadly. This approach is good for native wildflowers as well as trees, Scott says.
Some notable sites that highlight the effects of soil inversion include: Please Heath Common Shropshire and flower forestYorkshire's top site for Butterfly Records. Part of the philosophy behind this work is that the transformed patches can seamlessly become part of the landscape and local community. This means that many places where the soil has been “inverted” are not specially marked. One site in Runt, just four miles from Liverpool's wharves, attracted corn rails and short-eared owls.
Rewilding is often associated with hands-off approaches that rely on grazing animals, but this is often not possible where Scott and other enthusiasts work. “The truth is that true biodiversity can be achieved in many different ways and with different forms of stress and disturbance,” Scott says. “Soil inversion is a bit of a metaphor in that sense. I know it seems radical, but in a way it goes back to a more cultural connection that we had with the landscape.”

zero effect
To truly let nature take its course, sometimes we need to help it start from scratch. This is the approach taken at Porlock Vale in west Somerset. Rather than following the traditional route of restoring parts of the river to their current state, the National Trust is restoring the River Aller to its pre-human intervention by filling in parts of the main channel and allowing the water to flow naturally. Returned to “Stage Zero”. . Project manager Ben Ardley says it's part of a shift in thinking from seeing rivers as pipes to sponges, with dramatic effects.
“Since we reconnected the floodplain late last summer and into this year, insect populations on site have been visible and audible, and present in the clouds,” he says. “We then saw huge numbers of swallows, swifts and civets at that location, as well as an apparent increase in numbers of birds of prey such as kestrels, peregrine falcons and barn owls. You don’t have to be an ecologist or a scientist to identify that.”
Not only conservationists but also visitors from as far away as Japan are eager to see this work. “People often think in terms of agriculture and conservation, but we don't have to think so binary,” says Ardley. “You can graze these restored areas, you just have to think about it and do it a little differently.”
Although it has been far from smooth sailing for this project to get off the ground, the process has demonstrated the type of development needed if the UK is to deliver on its biodiversity commitments while mitigating extreme weather events. It became a touchstone for his bold approach. Will we abolish normative solutions to biodiversity and introduce what Ardley describes as “dynamic complexity”? A revolution may be in motion.
