Judging this enclosure from a single photo, it appears to be lush and possibly a fantastic exhibit for any number of mammals. I can picture Andean bears, coatis, bush dogs, red pandas, any number of felines, etc., all perhaps looking magnificent as they explore the landscape. Orangutans, on the other hand, would seem lost here with the lack of brachiating opportunities and in a totally inadequate exhibit.
I just realised there is an orang in this shot! Not sure I even noticed him on the day...
It certainly looks like it should also have otters in, and it's a real mystery why there aren't vastly more trees and ropes.
