Blue-Faced grazers

This caught my eye the other day. A PhD thesis on sheep populations. As I didn’t have my specs on at the time I thought it was an political map of sorts. But thought that a bit strange as I was looking for something about rewilding. Was struck by the similarity of density ( non pun intended) of Tory voters and where the majority of sheep live in Scotland. Just an observation really and doubt if there’s any sound statistical correlation.
