There isn’t anything like the North American appreciation of wildness in Europe. Still there are a few things. I’d be interested to hear of more, I’ll post what I can think of here.
Knepp Castle is a 3,500 acre estate in West Sussex, South East England. The owners got into rewilding (a bit at least). There’s a good article about it here:
http://www.theguardian.com/society/2007/may/09/ruralaffairs.conservation
and their website is http://www.knepp.co.uk/
It’s nothing much compared to the other side of the Atlantic, but it’s something. It also gives an insight into the difficulties of rewilding when surrounded by a population of ignorant compliant consumers.
