Campaigners are warning that England's ancient woodlands, some of the country's most precious and irreplaceable habitats, are facing unprecedented pressure from the government's ambitious housebuilding agenda. Despite stringent planning protections, dozens of sites are under threat from developments proposed on their doorsteps.

Protections Under Strain

Ancient woodlands, defined as areas continuously wooded since at least 1600, are havens for biodiversity. Planning policy states they should only be built on in "wholly exceptional circumstances", such as major infrastructure projects. However, the Labour government's pledge to deliver 1.5 million homes by 2029, coupled with the introduction of the "grey belt" policy, which allows development on poorer-quality green belt land, is putting these habitats at risk, campaigners argue.

Lucy Graebe-Watson, chair of Ancient Woodland UK, said: "We are already seeing cases where the existing protections are struggling. We have seen a rise in concerns and alerts from local groups since recent planning reforms." She fears the grey belt policy makes it more likely that land adjacent to ancient woodland, previously shielded by green belt laws, could be developed.

Communities on the Frontline

In Derby, more than 1,500 people have objected to plans for around 150 homes bordering Chaddesden Wood Nature Reserve. Helen Cherry, who has lived nearby for 40 years, described the wood as at least 400 years old, with mature hazel and oak trees. She said building to the edge of the woodland would leave it "closed on all sides", making a "mockery" of its nature reserve status. "Many a day I've been brought to tears, stopped and looked across the field where the buildings may occur and you can see right out across to the Derbyshire Dales," she said. "It's absolutely beautiful. If houses went ahead, the view would be completely obliterated - it would be very sad."

Derby City Council refused the plans in 2025, but surveyors were seen at the site over the summer, fuelling fears that developer JGP Properties Limited will return with amended proposals. JGP Properties said its assessments showed "no loss or deterioration of the ancient woodland and veteran trees".

Similar battles are being fought across the country. In Gillingham, Kent, approved plans for 450 homes within yards of Hook Wood have alarmed residents. In Rossington, South Yorkshire, more than 2,000 people have backed a campaign against a 130-home development near Gelster Wood. Gary Cantrill, a local beekeeper and member of the Preserve Littleworth Lane Group, said: "People feel our village is being treated as an easy target for developers who don't care about our community or our heritage. This isn't just an empty plot. It's 350-year-old historic farmland." He also raised concerns about flooding, as the fields currently absorb vast amounts of rainwater.

The Ecological Cost

Ecologists warn that even when trees are not removed, development can harm ancient woodlands. Matt Shardlow, an ecological consultant, explained that roots extending from the woods can be damaged, while drainage for new housing can dry out certain tree species and pollute water supplies. Noise and light pollution can also drive sensitive species away, and even pet cats can impact ground-nesting birds and bats.

The Royal Society for the Protection of Birds (RSPB) acknowledges that protections for irreplaceable habitats have improved under recent changes to the National Planning Policy Framework (NPPF). However, Carl Bunnage, head of nature policy at the RSPB, argues they remain inadequate. He said the "wholly exceptional circumstances" clause represents a loophole for developers, especially in areas with housing shortages. "If we can give the strongest protections to built heritage features such as historic buildings, then why shouldn't we also be giving the strongest protections to those habitats?" he asked.

A spokesman for the Ministry of Housing, Communities and Local Government insisted that ancient woodlands continue to benefit from "very clear and strong protections". He added that national planning rules explicitly state developments causing loss or deterioration should be refused, with very limited exceptions for nationally significant infrastructure, where compensation measures would be required. A revised NPPF published in August contains clearer policies for assessing proposals affecting irreplaceable habitats, the department said.

As the demand for housing grows, the tension between development and conservation is set to intensify. For campaigners, the message is clear: these ancient woodlands, which have stood for centuries, are too precious to be sacrificed.
