Wolves in Scotland?

The "Wolf Trust" is working to lay the groundwork for re-introducing wolves into Scotland, where they have not lived in 250 years. Part of the motivation is that ever-growing deer herds are changing the landscape by their overgrazing -- in some areas the alder trees they like to eat have disappeared and there is nothing left but evergreens. The problem, of course, is that while wolves like to eat deer they like to eat sheep even more.
