I read the position last night, and wasn't entirely surprised by it. I've never been under the impression that TUC is an angler's group (likewise Ducks Unlimited isn't a bird hunters group). Their mission statement is pretty clear on that. I think TUC are resigned to the closure decision, and they don't intend to expend energy fighting against something that appears to be pretty clearly written in stone at this stage. The statement is, at least, "conditional support" and does outline several of the very same concerns and confounding factors that those opposed to the closure have expressed. I might not entirely agree with their stated support of the closure, but it is pretty hard to disagree with much of the land use/habitat, angling, and enforcement pieces they go on to describe.
