A frozen zoo is a storage facility in which genetic materials taken from animals (e.g. DNA, sperm, eggs, embryos and live tissue) are gathered and thereafter stored at very low temperatures for optimal preservation over a long period (see cryopreservation). Some facilities also collect and cryopreserve plant material (usually seeds). SanDiegoZooSignOnStreet1.jpg Zoos such as the San Diego Zoo and research programs such as the Audubon Center for Research of Endangered Species cryopreserve genetic material in order to protect the diversity of the gene pool of endangered species, or to provide for a prospective reintroduction of such extinct species as the Tasmanian Tigerand the Mammoth. Frozen Zoo at San Diego Zoo Conservation Research has been freezing biological materials from animals and plants in liquid nitrogen (−196 °C) since 1976.[6] They currently store a collection of 8,400 samples from over 800 species and subspecies. Frozen Zoo at San Diego Zoo Conservation Research has acted as a forbearer to similar projects at other zoos in the United States and Europe including the Frozen Ark Project. However, there are still less than a dozen frozen zoos worldwide. At the United Arab Emirates Breeding Centre for Endangered Arabian Wildlife (BCEAW), Sharjah, the embryos stored include the extremely endangered Gordon’s wildcat (Felis silvestris gordoni) and the Arabian leopard (Panthera pardus nimr) (of which there are only 50 in the wild)
