It could take thousands of years for a cross-border peatland destroyed by fire to return to ecological health, a conservation group has warned.

The fire on Slieve Beagh raged for three days in May.

The bog is an important site for biodiversity and is home to the endangered hen harrier.

Roy Spence, from the River Blackwater Catchment Trust (RBCT), said it was "a battle" to get the ecosystem back to where it should be.
