Firefighters have issued a warning after a blaze ripped through a marsh at Calshot.

A field erupted into flames last Friday as five crews raced to Calshot Marshes to control the fire.

The blaze was eventually extinguished at around 10pm, though firefighters from Hardley did have to return to the scene the following morning to check for hotspots.

Flames and smoke were seen from as far as the Isle of Wight with people watching the incident unfold on webcams in Cowes, and at Netley Cliff Sailing Club.

One eyewitness, who asked not to be named, said the Calshot field went up "like a tinderbox".

Hampshire fire crews have now issued advice on how to prevent these wildfires from starting and how to keep the countryside safe.

Larry Mackrell, wildlife tactical advisor and group manager at Hampshire fire, said that "warmer weather increases the risk" for these fires, as it becomes easier for "barbecues, campfires and bonfires to spread out of control".

He added: “It is vital that people take extra care when visiting our green spaces, as fires in these areas can cause significant damage.

“By taking a few simple steps you can reduce the risk of a fire starting; extinguish and discard of cigarettes properly, put litter and glass bottles in a bin, take your rubbish home with you, and pack a picnic, not a disposable barbecue.”

Hampshire firefighters have asked those out in the countryside to follow rules and reduce the risks of fire, especially while the weather is warmer.

They say to never start campfires or take barbecues or lit charcoal of any kind to enclosed spaces like tents.

Hampshire fire says to never leave barbeques unattended and not to leave glass bottles in direct sunlight as they could start a blaze.

A spokesperson for Hampshire fire added: "Don’t start a fire or barbecue in areas that strictly state this is prohibited such as the New Forest National Park.

"Make sure cigarettes are out and correctly dispose of them."

The fire service also asks everyone using the countryside to take home their litter and keep a bucket of water or sand nearby in case of an emergency.

Hampshire fire also says to set up barbecues on level ground and to keep them away from dry grass, bushes, fences and other structures.
