Shot the first one over thirty years ago on Forestry ground at Netherfield, nr Battle, have never seen or heard another there.
Have seen quite a few near and around ground I hunt at Herons Ghyll over the last few years.
2-3 weeks ago I was barked at several times while stalking at Heathfield, the woodland is so thick there that it would be sheer luck to see it. I had pigs in the wooded valley 10 years ago, but they went when the farmer stopped rearing pigs in the adjacent fields.
I have two land owners near Nutley who say they have seen and heard them, mainly in their gardens, their gardens are huge bye the way, but to date have not seen any in either when I have been hunting the woods around.
