Hundreds of pigs will snack on acorns and beechmasts for the next two months as the New Forest’s annual pannage kicks off.

The autumn tradition, dating back centuries, improves the condition of the soil and reduces the risk to ponies and cattle, who can be poisoned if they eat too many nuts and acorns.

Up to 600 domestic pigs have been released for around 60 days by people who occupy surrounding land in Hampshire.

“They have a wonderful time while they’re out there,” Sue Westwood, clerk to the verderers of the New Forest, told the PA news agency.

“They’ve got free range of the forest.

“We do always say to people not to get too close – they can be a bit spiteful.”

While Ms Westwood warned against approaching any of the pigs, she maintained the animals love pannage as it helps to fatten them up.

“Sometimes we extend the pannage season a bit if we still (have) a lot of acorns and we think that the pigs can still do some good,” she explained.

“Pannage is one of the old rights of the forest so it goes back hundreds of years.”
