Danes Moss Wildfire Latest Example of Rewetting Failure

There is a particular kind of institutional embarrassment that comes from being proven wrong by the people you spent years dismissing. The wildfire at Danes Moss Nature Reserve on Tuesday should be producing exactly that feeling in the offices of every conservation body and every DEFRA official that spent the last decade telling moorland managers, gamekeepers and land agents that they don't know what they're talking about.

They knew. They said so. Nobody listened.

For generations, the people who actually live and work on the uplands and lowland mires of England have understood something that conservation policy has consistently refused to accept: that unmanaged vegetation is fuel, that fuel accumulates, and that accumulated fuel burns. The solution they have practised — carefully, knowledgeably, across centuries of accumulated craft — is controlled burning. Rotational management of surface vegetation that reduces fuel loads, breaks up the continuity of combustible material, and protects the underlying peat from the catastrophic burns that rewetting's advocates claim to fear most.

The conservation establishment's response to this expertise has been contempt dressed as science. Gamekeepers were portrayed as self-interested. Controlled burning was reframed as an act of environmental vandalism. The Moorland Association and those who manage grouse moors were systematically characterised as opponents of nature recovery rather than its most experienced custodians. And in their place, rewetting was elevated to something close to doctrine — the single, sufficient answer to every threat facing the UK's degraded peatlands.

Then came the Heather and Grass Burning Regulations 2021. DEFRA's decision to ban rotational burning on blanket bog SSSIs was presented as a landmark moment for peatland conservation — evidence-based, scientifically sound, long overdue. It was nothing of the sort. It was ideology codified into statute. Moorland managers, gamekeepers, land agents and the organisations representing them said with remarkable consistency and clarity what would follow: fuel loads would accumulate unchecked, surface vegetation would thicken and dry, and the peatlands that the ban was designed to protect would become progressively more vulnerable to the uncontrolled wildfires that controlled burning had historically suppressed.

DEFRA did not engage seriously with that argument. It had campaign groups to satisfy, a political narrative to maintain, and a conservation sector broadly cheering the ban from the sidelines. The voices of the people who actually manage the land were processed as lobbying to be discounted rather than expertise to be weighed.

Danes Moss, managed by the Cheshire Wildlife Trust, is what discounting that expertise looks like on the ground. It is a Site of Special Scientific Interest. It is the largest lowland raised bog in Cheshire. It is, by any measure, a flagship conservation site — the kind of place where best practice is supposed to be demonstrated, not discovered to be wanting. On Tuesday afternoon it burned. Four fire engines and an all-terrain vehicle were needed to stop it. A boardwalk was destroyed. And the only reason the peat itself survived was that a member of the public happened to call 999 in time.

That is not a management success story. That is a near miss dressed up in a press release.

The defence being offered — that the peat didn't ignite, that the rewetting held at depth — is precisely the argument that moorland managers have been making about controlled burning for years, and which the conservation sector has refused to accept.

Managed burns on properly rotated heather do not penetrate peat either. They are conducted in conditions specifically chosen to prevent it. The difference is that controlled burning is a deliberate intervention, carried out by skilled practitioners, at a time and scale of their choosing. What happened at Danes Moss was an uncontrolled fire in March, extinguished by the fire service, with infrastructure damaged and the reserve left ecologically stressed at the start of the growing season.

The deeper problem is this: rewetting addresses hydrology. It does not address fuel load. In a warming climate with drier springs and longer fire windows, a rewetted peatland with decades of accumulated surface vegetation is not a protected habitat. It is a waiting fire. The water table may be rising. The biomass above it is still there, still drying out each spring, still waiting for a discarded cigarette or a carelessly used barbecue or a child with a match. The 2021 regulations have not made these sites safer. They have methodically removed the one tool that kept surface fuel loads in check, left land managers with no legal means of intervention, and handed the job of fire prevention to the fire service and to luck.

This is not conjecture. It was the explicit, detailed, repeatedly stated prediction of the people who opposed the ban — and who were dismissed, briefed against, and in some cases publicly vilified for saying it. The wildfire record on unmanaged and rewetted peatland sites since 2021 is not encouraging. Danes Moss will not be the last. In a dry spring, it may not even be the worst of this season.

Moorland managers have a word for the alternative: management. Not rewetting instead of burning, but burning as part of a broader toolkit — alongside grazing management, drain blocking, and yes, rewetting — that keeps fuel loads in check, maintains habitat diversity, and reduces the catastrophic fire risk that unmanaged vegetation inevitably creates. The empirical record of well-managed grouse moors, where rotational burning has been practised continuously, does not show the ecological devastation that campaign groups promised. It shows, in many cases, lower wildfire incidence, better structural diversity of vegetation, and populations of ground-nesting birds that rewetted nature reserves have conspicuously failed to deliver.

None of this is comfortable for the organisations that lobbied hardest for the burning ban, or for the DEFRA ministers and officials who signed it into law without adequately testing the consequences. But Danes Moss is now on the record. The question of what accumulating fuel loads will do to unmanaged peatland sites in a warming climate is no longer theoretical. It is a Tuesday afternoon in March, 2,500 square metres of burned reserve, and a conservation body that should be asking whether the policy framework it helped create has made its own nature reserves harder to protect.

DEFRA should be asking the same question. It won't, without pressure. But upland communities already know the answer. They gave it in 2021. They were ignored then. The case for listening to them now has never been stronger — or more urgent.
