I wonder if they will try planying more trees in the area, considering the pigs killed a few since moving in?
I know that, and I also know that they are having a real problem with the plants in there and any they have planted due the destructive nature of the pigs.
Sooner or later, all pig enclosures look like this. I think pigs should be housed in paddocks in rotation with other medium sized hoofstock etc. After a year or so, the stock can be moved around and the paddock which the pigs have demolished can be re-landscaped, replanted and left to recover, then something less destructive can be moved in as part of the next rotation.
