The wolf is considered a threat to our way of farming, but our fear may be misplaced. Perhaps predators are needed to bring nature back into balance

There’s a monument near Brora, 60 miles short of John o’Groats, that claims to mark the spot where the last wolf in Sutherland was killed. I pass it often in the car. The wolf, it says, was killed by the hunter Polson in or about the year 1700.

I know this story. Polson, so it goes, was standing watch outside the wolf’s lair while his sons laid waste to the pups inside. When the she-wolf returned from the hunt, racing to the aid of her young, she bounded past the hunter and, as she did, he grabbed her by the tail. From inside the den – now plunged into darkness as Polson and the wolf struggled at its entrance – came, in Gaelic, a shout of alarm: “Father! What’s blocking the light?” To which Polson replied: “If the tail comes away at the root, you’ll soon find out!”
