Plenty of livestock systems around the world work alongside predators. It’s called having shepherds or cowherds along with big dogs who look after the animals, live alongside them, corral them at night and keep predators and thieves away.
Sheep on most farming systems in the UK are only there because of subsidies. Wool no longer even covers the cost of shearing and lambs don’t make a lot of money.
Indeed with the price of land these days about the only profitable crop is windfarms, solar farms or housing. No way can the margins on most arable cover the interest let alone any capital repayments on land.
Contractors to shoot deer cost upwards of £100 a beast. For a full time employee to manage deer you are probably spending best part of £100,000 by the time you have added in vehicles, overhead cost and housing (especially if you take the opportunity cost of a house that rented out for a lot more).
And there are plenty of very wealthy individuals that are buying up large tracts of the UK’s land. And there are plenty of large corporations that will spend good money on carbon credits so they can greenwash their corporate image, and sell this dream to pension funds etc.
Add a few wolves to the situation, in the same way that former ranchland in Southern Africa now has cheetahs and lion all getting fat on impala, kudu etc, and you get even more green points with the green washers.
Buy a big chunk of land, stick on windmills and wolves and you are the big swinging blue eyed wonder of the corporate world. And then charge tourists to see the wolves.
It makes bugger all sense to most on SD, but this is the reality of modern UK.
