Wot, you mean like reducing numbers of sheep on the mountains and moors, so that the heather and ling is old and shrubby and crowds out new growth and wild flowers, with all the associated birds and insects? The drainage channels fill up with vegetation and make the ground so boggy it's too wet for the waders to nest. Bog asphodel spreads and sheep can no longer graze the land at all, as it's poisonous to them ....? Yup, I'm a shepherd and somehow I just know he isn't.
