The Mourne Heritage Trust estimates April’s Silent Valley fires scorched up to 1,700 acres, leaving “virtually nothing” behind, according to Andrew Baird, who surveyed the damage near Ben Crom dam.

The fire, which burned for four days, had to be fought manually. “There was water at all around here and we were just using shovels,” said Baird, who questioned why no helicopter support was provided.

The Department of Agriculture, Environment and Rural Affairs (DAERA) said it would consider a seasonal fire ban. The Northern Ireland Fire and Rescue Services (NIFRS) said a helicopter was not used due to factors like wind speed, fire behaviour, and ground crew safety – not due to budget concerns.

Rebecca Allen of NI Water, which manages Silent Valley Reservoir, said a full ecological survey hasn’t yet been possible. She described the habitat as a rare mosaic of deep peat, heather, and moss, now exposed to erosion. While there is no immediate risk to drinking water, treatment costs may rise.

Local environmentalist John Ross McMahon, who witnessed the fire along Sandbank Road, said some damage is likely permanent. In areas where fire burned deep into the peak, “the soil has essentially collapsed.”

He and Baird agree that active restoration is essential. Mourne Heritage Trust is piloting hydroseeding – spraying seed mixtures to encourage regrowth – but recovery may take up to a decade.

Daera noted that a new peatland restoration funding is in place and a broader Peatland Strategy will be launched once approved by the Stormont Executive.

Mr Baird urged a ban on fires during amber or red wildfire warnings to prevent future devastation.
