Oh right, ok. And I forgot about the place being fenced off from predators, which can't help. Despite being a limp vegetarian I do say 'send in the ferrets' I think.
It's ridiculous to say things can't be done because it's an SSSI, it's only chalk grassland Because of the grazing regime.
And to say they won't pay for it - well why don't they (because of the insurance, yes) just ask for some bloody volunteers for the scrub removal, I'm sure they'd have plenty of takers.
In fact why don't some people just go and DO IT and by the time EH have got off their office chairs to tell them off it'll all be done.
