In 1980s, there were fewer than 200 of these lizards left in the world, all of them living on the small island of Anegada, the northernmost Island of the British Virgin Islands. Introduced predators and habitat destruction had reduced their numbers to a critical low. The one of biggest challenges for the species was that all of the hatchlings were being eaten by feral cats, resulting in the population consisting only of aging adults. If the San Diego Zoo had not stepped in, the species would have gone extinct. Working with the British Virgin Islands National Parks Trust, the Fort Worth Zoo, and The Caribbean Wildlife Foundation, San Diego Zoo Global began an effort in 1997 to jump start the species. They started by bringing baby iguanas into an on-island facility where they were raised until they were large enough to survive on their own. Successfully rearing these animals required the husbandry experience of Zoo, knowledge that has since been shared to the in-country partners. Since 2003, over 200 head-started iguanas have been released on Anegada, resulting in a near doubling of the wild population. Zoo scientists continue to observe the population and guide the program to ensure healthy genetics among the lizards. The commitment and expertise of the San Diego Zoo has been vital in saving this species from extinction and providing …show more content…
San Diego Zoo Global has worked to save rhino species from extinction. The combined efforts of the veterinary staff and conservation scientists have led to over 90 Southern White Rhinos born at the San Diego Zoo since 1974. The Zoo also works with the International Rhino Foundation as a member of their Zoo Partners Program. With funding from the San Diego Zoo, the International Rhino Foundation works to protect vulnerable white rhino populations in South Africa. They also develop new methods to combat and reduce poaching. In addition, they have gathered eggs, sperm, and other genetic material from rhino, which are stored in the Frozen Zoo.
The Frozen Zoo located in the San Diego Zoo Conservation Research Center, is a collection of unique low-temperature units containing genetic materials from 10,000 living cell cultures, sperm, and embryos. These genetic materials represent nearly 1,000 animals, including one extinct species. The purpose of the facility since 1972, is to sequence as much DNA from extinct or rare species with hope to reintroduce them to the world one day. So far there are a few Frozen Zoos in the US, but Frozen Zoos have been developing in Australia like the Animal Gene Storage and Resource Center of
