Yes, they are still on the hardstand; no, there appeared to be no sign of a dividing fence being erected. There are other ZooChat contributors better placed to comment on giving the wildebeest access to the paddock, so I’ll leave it to them to answer.
They're definitely planning to give them paddock access, but, like with proper branchiation for the gibbons, I have no idea when or how at the moment as it seems to be constantly fluctuating. It looked like this would happen last summer when scaffolding for a fence boundary appeared in the paddock, but this seemed to disappear overnight.
