The cause of a huge wildfire that destroyed parts of a nature reserve could not be determined, according to a fire service.

Large parts of Dunwich Heath and of the neighbouring RSPB Minsmere on the Suffolk coast were destroyed by a fire the size of 210 football pitches, which started on 29 July.

It took Suffolk Fire and Rescue Service two weeks to stand down from the scene and while investigations have identified where the fire originated, its cause remained undetermined.

A spokesperson for the fire service said the severity of the blaze had meant any potential evidence on its cause had been destroyed.

"Following a detailed investigation into the Dunwich Heath wildfire, Suffolk Fire and Rescue Service has concluded that the cause of the fire cannot be determined," it said.

"While investigators were able to identify the general area where the fire originated, the severity of the fire meant that any potential evidence that may have identified a cause was destroyed."

It added: "Although the cause remains undetermined, this incident serves as a reminder of how quickly fire can spread during periods of prolonged dry weather.

"We continue to encourage residents and visitors to take extra care in the countryside and follow wildfire prevention advice to help protect Suffolk's communities, wildlife and landscapes."

Watch: Smoke fills the sky from heathland fire

Tristan Gale, Suffolk County Council's cabinet member for the fire service, thanked those who had been involved in the response to the incident.

"While it is disappointing that the exact cause cannot be conclusively established, the incident reinforces an important message for all of us," he said.

"As periods of hot, dry weather become more common, we must all remain vigilant and do what we can to stop the risk of wildfire."

At its peak, 120 firefighters were at the scene, with all 35 of Suffolk's stations involved and many other crews called in from other counties.

The fire caused nearby holiday parks to be evacuated and volunteers stepped in to house those who had been displaced.

Local farmers also helped to create firebreaks to slow the spread and ultimately no properties were lost.

There had also been some positive signs of nature returning to the area.
