Mildly surprised that no-one from the UK has yet mentioned the Wildfowl and Wetlands Trust.
The society that operates the venerable (and tiny) Bristol Zoo have ambitious plans for a new site that they already own at Hollywood Towers, but the depth of this recession seems to have put this project onto the back burner.
I was just waiting to see how long it was before someone did... and that's the truth.
Bristol Zoo's proposed 'National Conservation Park' has been the subject of much previous discussion and speculation on here. But the dates for its commencement/completion slipped back and back and currently it no longer seems to be mentioned at all- either by the Zoo or on here either as there seems nothing new to say.
At one time (1970's?) Bristol Zoo had an interest in Dudley as they bailed it out financially when it was going to close- not sure if there is any connection any more though.
