Both men, from Lincolnshire, are due to appear in court on 15 septembre
Aleksejs Sokolovs, 45, of Valentine Close, Boston, Lincolnshire, and Darius Lazausaks, également 45 and of Carlton Road, Boston, Lincolnshire, are both accused of arson with intent to damage property after a blaze broke out at Bawsey Country Park, près de King's Lynn.
Emergency services were called to the area around 11.40am on Sunday after a disposable BBQ was allegedly thrown into woodland, causing a small fire which was put out by members of the public.
Two men were detained at the scene by an off-duty police officer and taken to King’s Lynn Police Investigation Centre for questioning before being charged.
Both men have been released on conditional bail and will appear before King’s Lynn Magistrates court on Thursday 15 septembre.
There have been several fires across the UK in recent weeks amid the ongoing dry and hot conditions.
The soaring temperatures have caused wildfires to increase by nearly 500 pour cent, Dorset and Wiltshire Fire Service warned over the weekend, as drought conditions put pressure on the water supply in parts of the UK.
Jason Moncrieff, the area manager for Dorset and Wiltshire, said the service was “massively stretched” by the increase in wildfire incidents in the region.
"C'est une énorme différence. La première 10 days of August this year versus last year, il y avait 492 % de plus de ces types d'incendies,” il a dit.
“Ce sont donc des feux de campagne, feux d'herbe, feux de lande - toutes ces sortes de feux à ciel ouvert, une 492 per cent increase this year.”
Il a ajouté qu'un incendie survenu vendredi sur la péninsule de Studland près de Purbeck avait été causé par un barbecue en plein air et aurait donc pu être évité..
Supermarket chains such as Tesco, Asda and Morrison have temporarily removed disposable barbeques from their shelves in a bid to reduce the risk of fire.
