This is what the slope looks like before the pigs are on it - a tangled mass of gorse etc
And after they've been on it a while... this one taken from the bottom of the slope looking back up the hill. It really is amazing!
John has them on a steepish gorse covered slope, which they happily rooted about in, and it is stunning to see how effective they are at clearing the thicket of gorse etc, leaving John free to move them on and then seed the area they've cleared.
