Core Event
Across historic estates in England and Scotland, large-scale rewilding programmes are delivering measurable ecological and social outcomes. Projects on the National Trust’s Holnicote estate, the Broughton Hall estate (Broughton Sanctuary), the Castle Howard Estate (Bog Hall scheme) and Trees for Life’s Dundreggan centre have restored wetlands, planted native trees, re-introduced keystone species and linked nature exposure to mental-health improvements.
Background & Context
Decades of intensive agriculture have left the United Kingdom with a loss of over 90 % of its wetlands, according to the Guardian. Land-owners and charities are now treating nature as infrastructure to build landscape resilience against heatwaves, droughts and wildfires.
Data & Statistics
- Holnicote’s re-engineered rivers and restored wetlands stayed green through five consecutive summer heatwaves, while surrounding fields browned (Guardian).
- Broughton Sanctuary spans roughly 2,500 acres; its Nature Recovery team has planted more than 340,000 native trees and recorded about 1,750 wildlife species.
- All five British owl species now breed on the sanctuary, a milestone described by staff as unprecedented.
- Beaver activity and Iron-Age pig introductions are creating ponds, willow stands and bare-ground niches for wildflowers.
- The Bog Hall scheme on the Castle Howard Estate is a 30-year effort that recently introduced a rare herd of White Park cattle; beaver releases are planned for autumn.
- Dundreggan rewilding centre hosts over 4,000 plant and animal species and serves as a field site for a mental-health research programme involving secondary-school students.
Official Statements & Responses
National Trust director of land and nature Harry Bowell urged the government to increase investment in nature-based solutions, emphasizing that climate change “is happening here and now” and that treating nature as essential infrastructure can create more resilient landscapes (Guardian).
Verbatim Quotes
- “Nature is providing solutions to some of the biggest challenges facing society today,” — Ben Eardley, project manager, Holnicote estate
- “It’s places like Holnicote where nature is showing us the way – demonstrating how, by treating and investing in nature as essential infrastructure, we can create landscapes that are more resilient to benefit communities and nature alike.” — Harry Bowell
Why It Matters
Restored wetlands on Holnicote have acted as natural firebreaks, countering claims that rewilding fuels wildfires. The return of apex predators and all native owl species on Broughton Sanctuary shows how trophic cascades can be re-established when habitat connectivity improves. At Dundreggan, engaging teenagers in nature-based activities has already shifted attitudes toward outdoor wellbeing, indicating mental-health dividends alongside ecological ones.
Conflicting Reports & Gaps
No source provides long-term monitoring data to quantify how rewilded wetlands affect regional flood risk or carbon sequestration over decades. Further research is needed to confirm whether the observed biodiversity gains translate into measurable ecosystem services at the landscape scale.
What’s Next
- Castle Howard plans to release beavers in autumn to enhance water retention and create additional wetland habitats.
- The Healthy Young Minds team at Dundreggan is preparing two academic papers and seeking funding to expand nature-based mental-health programmes with NHS Highland and local charities.
These initiatives illustrate a growing movement to embed rewilding within UK land-management strategies, positioning nature as a multifunctional asset for climate adaptation, biodiversity recovery and human wellbeing.
