Don't tell my crofter pals, but

I rather fancy there's room for a couple of small packs in Scotland and I'd be more than up for it. European population estimates for large carnivore distribution:
http://ec.europa.eu/environment/nature/conservation/species/carnivores/conservation_status.htm
Whilst there are a few folk killed by bears every other year in eastern europe (Romania) we don't hear about similar issues with the wolf, despite there being some 15,000+ individual animals estimated to be present within the EU. The greatest 4 legged hazard to the human population is, unfortunately, the domestic dog.
There are however issue for animal husbanders and deer mis managers, stalkers etc. Stock will be lost and stalkers will have to relearn deer movements anywhere the wolves pass. The data from Yellowstone is quite encouraging and the benefits to the native flora, irrefutable. However, as husbanders rely to no small extent on subsidy it wouldn't be beyond the realms of practicality to extend or reconfigure subsidy payments to encourage pasture woodland improvements and compensation for lost livestock (we'd need to keep an eye on that mind, French shepherds are claiming 2,500 lost sheep, and thats not bad going for 100 wolves

). The wolf gets out of hand? shoot them. Improve the habitat and everything benefits, including the lot of upland farmers with grazing animals.
Deer stalking would benefit too, stalking on many estates these days is woefully artificial. A thinning of numbers, a spooked and on the move population; would greatly improve the experience for people who are genuinely into stalking rather than, as it is for most, a modern stalking spectacle more akin to a turkey shoot. I tender that the only people really experiencing true stalking these days, are those who still poach for the pot on the hill, and there aren't many of those at that these days.
