Apparently the government is about to reveal new grey squirrel control strategies early next year, which are rumoured to possibly legislate for landowners to have to take compulsory measures to cull them. That's a moral minefield. "Thou shalt kill or be punished for not killing?"
http://www.bbc.co.uk/news/uk-30241900Personally, I'd have thought the most effective strategy from a govt point of view would be a bounty. (fee per squirrel head, not the coconut bar).
While accepting the case for control and recognising it would be wonderful to see a widespread return of the red, I would feel uncomfortable with a duty to personally carry out the killing. If a fee was paid to cover the cost of getting someone else to do it and I personally didn't have to pull the trigger, that would be an agreeable compromise. Hence why a bounty system might work.
