A lot of effort and money has also been spent planting both zoos with exotic plants. In fact both zoos are very much botanical gardens as well. Plenty of water features, like ponds, moats, cascades, found in almost every exhibit. The climate allows for great outdoor displays of tropical species. The Singapore Zoo is also known as the 'Open Zoo'.
Enclosures are all nicely 'furnished' with branches, logs, rocks, plants, pools, etc.
They are refurnished every few months. The only iron-barred exhibit in the Zoo house the pumas. It is pretty old and small. No iron-barred exhibits at the Night Safari at all. Most of the conservation is done within the zoos , in the captive breeding of endangered species.
