- England's current woodland covers only 10% of the country and current regenerative plans are only planning to increase this by 2%, by 2050.
- If woodland cover was increased to 26%, 10% of the nation's carbon would be adsorbed naturally, whilst supporting dwindling wildlife.
- Rewilding - allowing woodland to regenerate naturally on a large scale - is the most effective way to increase woodland cover.
Allowing trees to naturally establish over huge areas could massively expand Britain’s woodlands more effectively and at a fraction of the cost of tree planting, according to research by Rewilding Britain.
Britain is one of Europe’s least wooded countries. Rewilding Britain says the UK government’s draft England Tree Strategy, open for public consultation to 11 September, is woefully inadequate for tackling the climate and nature crises. More ambitious targets and a fresh approach are needed.
Rewilding Britain supports a doubling of the country’s woodland cover over the next decade, from 13 percent now to at least 26 percent. This could help absorb 10 percent of current UK greenhouse emissions annually, and help declining wildlife.

But the government’s draft strategy for reforestation in England fails to set any tree targets, and at best would raise English woodland cover from 10 percent today to just 12 percent by 2050.
The government’s unambitious plans also focus on manual tree planting as a quick fix. But a Rewilding Britain study to be published later this year shows that allowing and enhancing natural regeneration – supported by native tree planting in suitable sites – would be the most effective long-term approach for landscape-scale reforestation.
“We urgently need an expansion of nature’s recovery across Britain that matches the scale of the threats from accelerating climate heating and species extinction – with clear and bold targets from the Government,” said Rebecca Wrigley, Rewilding Britain’s Chief Executive.
“We can’t replace our lost woodlands by planting alone. Protecting ancient woodland fragments, and allowing and assisting trees to naturally regenerate on a big scale, is the most effective way of reversing the sorry fortunes of our crippled forests and woodlands, and so benefiting people, nature and the climate.”
Letting trees and shrubs naturally regrow over much of their former landscapes – with a helping hand where needed, such as preparing the ground when necessary or sowing tree seeds when naturally available seed sources are too far away – would create woodlands better able than plantations to soak up carbon dioxide, support wildlife, and adapt to a changing climate. Costs and management, imported tree diseases, and plastic tree guards would all be reduced.
A doubling of Britain’s woodland cover would include areas of land over which young trees are naturally establishing, and which will grow into the forests and wildwoods of the future.
Major barriers to natural regeneration are attitudes towards scrub – a superb habitat and nursery for young trees, but often seen as a waste of space or untidy – and over-grazing of trees by herbivores.
The government’s new Environmental Land Management Scheme should address these challenges by offering landowners financial incentives for allowing natural regeneration of trees – avoiding the pitfalls of previous schemes which penalised landowners for unmanaged areas – and support marginal upland farming in shifting from low-productivity sheep and deer ranching to rewilding.
How UpLink is helping to find innovations to solve challenges like this
UpLink is a digital platform to crowdsource innovations in an effort to address the world’s most pressing challenges.
It is an open platform designed to engage anyone who wants to offer a contribution for the global public good. The core objective is to link up the best innovators to networks of decision-makers, who can implement the change needed for the next decade. As a global platform, UpLink serves to aggregate and guide ideas and impactful activities, and make connections to scale-up impact.
Hosted by the World Economic Forum, UpLink is being designed and developed in collaboration with Salesforce, Deloitte and LinkedIn.
To double Britain’s woodland cover, the government should raise annual investment from £50 million now to at least £500 million. Economic benefits would include jobs in forestry, tourism and ecosystem restoration. The many benefits of trees – carbon drawdown and storage, flood mitigation, urban cooling, improved soil and water quality, and wildlife habitat – far outweigh such upfront costs.
Rewilding Britain says natural regeneration of woodlands should be part of broader rewilding – the large-scale restoration of nature by letting it take care of itself. This includes better protection for ancient woodlands, and ensuring a diverse mix of better-connected habitats.
Evidence from around the world highlights the benefits of natural regeneration. In Eastern Europe and the former USSR, vast spontaneous reforestation since the Soviet Union’s collapse includes most of over 58 million hectares of abandoned croplands in Russia and Kazakhstan.
Flourishing broadleaved forests in coastal southern Norway – once as deforested and bare as much of Britain today – demonstrate how natural regeneration might happen in upland areas like Cumbria without intense grazing pressure and detrimental management such as moorland burning.
Evidence from Friends of the Earth shows there is more than enough suitable land to double England’s tree cover, without affecting precious habitats such as peatlands or valuable farmland.
“Our ancient woodlands are only absent because we’ve destroyed them and continue to work hard to prevent their return through over-cutting, over-mowing and over-grazing. If we let them, millions of trees would plant themselves across most of Britain,” said Rebecca Wrigley.
Rewilding Britain wants rewilding to flourish – to tackle the climate and extinction crises, reconnect people with nature, and inspire people through new opportunities.
