Its actually a valuable large exhibit area pretty much right in the centre of the Zoo. If they had money, I think the sensible thing to do would be to deconstruct this enclosure completely and use it for some sort of major new build- any species is possible really.... But as they haven't, it will probably just stay as it is with the Camels.
Its a pity they don't have giraffes any more-IMO a major loss. This enclosure might not seem very suitable for them now but I would like to see them return on a more open site there.
