Wild deer are the big issue. There's a small but vocal community pushing for wolf reintroduction, but that has it's own challenges. Scottish land law is extraordinarily complicated and archaic, it remain solely to prevent extinction of a far more damaging animal: the Edinburgh Lawyer.

I'm rarely as concerned about northern forests though. Fir trees count for half, or less, IMO. Without beech, silver birch, oak and yew the forest is fake.

Bring back the wolf, I say.
