Conservationists have revealed the latest weapon in their fight to preserve and restore threatened heath land in Dorset, England.

Normally it would be an expensive piece of machinery but this time it is something more unusual - a rare breed of hairy pig.

The Mangalitsa pigs will spend a year eating all the rotting plants and wood from the top of the land to get it back to it's natural state.

James Warren is the pig's keeper and told us why they are special.
