You could try the gamekeepers, someone will have a link. I think what you will find is that anyone with an affinity for the land and for nature will be against the un-natural support of any species. Those who understand the land and nature have cared for it for centuries. As will always be the case there were times when certain species were targeted. Peregrines in particular during the wars, when pigeons were the heroic lifesavers of many. We are now in an age where the Peregrines have protection far beyond that which is required. They are now reaching vermin status along with sparrowhawks, etc, destroying the songbird populations and centuries worth of ways of life for many, notwithstanding the employment of many.
