PIGS will be busy performing an important role in the New Forest for the next two months.

Pannage season started yesterday and will run until November 11.

The ancient custom sees New Forest Commoners release their pigs - also known as common of mast - into the Forest each autumn.

The tradition goes all the way back to the time of William the Conqueror.

Pigs play an important role in the management of the Forest by eating acorns, particularly green ones, which are poisonous to ponies and cattle.

They also eat fallen beechmast, chestnuts and other nuts.

Around 600 pigs and piglets work their way through the Forest each year.

They must be fitted with a ring through the nose which enables them to forage but stops them from causing damage to the Forest with their snout.

Some of the breeds of pig that can be found include Tamworth, Gloucestershire Old Spot, the British Saddleback and the Wessex Saddleback.

It is the only time they are allowed to roam the Forest.

Last year’s pannage season was extended to December due to an abundance of acorns.
