The Banteng is an ox. Hunting pressure and loss of habitat are just two things that make bantengs endangered. Southeastern Asia has endangered this species. Wild cattle habitat is prime for domestic cattle and the introduction of disease from livestock also threatens bantengs in the wild. As of February 2005, the banteng population of the Cobourg Peninsula is 10,000, making the population in the Northern Territory the largest herd in the world. It was believed that only 5,000 pure-strain Banteng survived worldwide. In their native range the largest herd numbers were less than 500 bantengs. Some Banteng were introduced to Northern Australia during British colonization in 1849 where they are doing extremely well having grown in numbers. The SSP is trying to save the banteng, they've taken them a long ways. Now, There are about 1.5 million domestic bantengs, but there aren't even close to as many banteng left in the wild.
As a carnivore the African wild Dogs 'weed out' sick animals. They also create competition with others. Most believe that African Wild Dogs are a threat to livestock, but very rearly do they attack livestock. The African Wild Dog is endangered because of Domestic dogs bringing disease to them. The diseases include: rabies, distemper, parvo, adenovirus, coronavirus, and herpesvirus. Another reason is because traffic injur or kill the African Wild Dog. Other factors of the numbers going down is: competition with other larger carnivores, limited food supply, and predation by lions and occasionaly hyenas. In Southern Africa the Wild dog is possibly visible, Mid Africa is probably not visible, little parts of east and west Africa they are probably extinct, and the southern part of Africa they are Extinct.
Cheetahs are listed as a vulnerable species. There are only an estimated 9,000-12,000 left in the wild. Cheetahs are adapted for life on grassy plain but humans are taking that away from them. The main threat to cheetahs is loss of habitat because of human settlement and agriculture. But people are trying to reintroduce the cheetah.
Elephants are increasingly threatened by human intrusions and poaching. Elephants were once numbering in the Millions. Now the African Elephant population has dwindled between 470,000 and 690,000 individuals. The Elephant is now a protected species worldwide with the restriction in place on their capture, domestic use, and trade in products such as ivory.
In 1930 there were between 5 and 10 million African Elephants. By 1979 there, were 1.3 million. In 1989, (when they were added to the international list of most endangered species), there were only 600,000 elephants remaining in the wild, less then one percent of their original number.
In an effort to save this species from extinction, a Species Survival Plan (SSP) was created through the American Zoo and Aquarium Association (AZA). The SSP goals include island wide education and outreach, research, the protection of existing habitat, the creation of new ponds, and the establishment of at least five reproducing populations in the wild. A reintroduction program is a large factor of the recovery plan for this species. Each year, captive toads from zoos and aquariums in the United States and Canada are bred, and tadpoles are sent to Puerto Rico for release.
The Puerto Rican crested toad once flourished on Puerto Rico and Virgin Gorda. The toad’s decline has led to a listing as being threatened by the United States Fish and Wildlife Service and Critically Endangered by the International Union for Conservation of Nature and Natural Resources. Right now, the only known wild population is the southern form, which is a small pond located within Guanica National Forest.
