The polar bears’ new home will be housed within River Safari’s Frozen Tundra exhibit, which aims to educate visitors on the importance of glaciers and semi-frozen freshwater ecosystems, amongst the most threatened of the world’s biomes.
The polar bear dens and indoor areas will be climate controlled, with temperatures that simulate the Arctic north. Three viewing elevations will be available for visitors, including the hugely popular underwater view, and visitors can admire the animals through windows cut into frozen rocks.
Modelled closely after their natural habitat, Inuka and Sheba’s new home is part of WRS’ commitment in upgrading these bears’ living space. In 2006, the Animal Welfare and Ethics Committee (AWEC) decided that it was in the polar bears’ best interest for them to remain in Singapore. This decision was reached after considering the animal’s ages, their familiarity with their keepers and environment, and the uncertainty of whether other facilities would be able to provide the same high level of care that Inuka and Sheba are used to. It was also at this time that WRS started the conceptualisation of the Frozen Tundra exhibit, to further upgrade the polar bears’ habitat.
Native to the Arctic Circle, polar bears are the world’s largest land carnivore and adult males can weigh up to 650 to 700 kg. Classified as vulnerable by the IUCN, the bear occupies a narrow ecological niche and preys almost exclusively on seals. Polar bears hunt mostly on ice floes in winter months and retreating sea ice due to global warming has resulted in the diminishing of their hunting grounds and food sources. If global temperatures continue to rise, polar bears may become extinct across most of their range within a hundred years.
Some of the innovative features of Frozen Tundra include “ice rocks” where our polar bears can soak in the coolness of “freezed” rocks and also an ice cave where both Sheba and Inuka can retire to, so as to enjoy a polar siesta. The new habitat also incorporates a large freezer unit able to produce huge blocks of ice as enrichment for the bears. Natural substrates, trees, and also pools and streams will be incorporated, to provide the bears with a rich and varied home.
As construction begins on the Frozen Tundra exhibit, the polar bear enclosure at the Singapore Zoo will be closed from 30 August 2010. Inuka and Sheba look forward to seeing everyone again in 2012 with the opening of River Safari.
New habitat for Singapore’s polar bears will be three and a half times bigger and feature innovative climate-controlled features
