The world's fastest land mammal is racing toward extinction, with the latest cheetah census suggesting that the big cats, which are already few in number, may decline by an additional 53 percent over the next 15 years.
"That's really perilous," says Luke Hunter, president and chief conservation officer for Panthera, the global wild cat conservation organisation."That's a very active decline, and you have to really step in and act to address that."
Today there are just 7,100 cheetahs left in the wild, according to the new study, which appeared recently in the Proceedings of the National Academy of Sciences. That's down from an estimated 14,000 cheetahs in 1975, when researchers made the last comprehensive count of the animals across the African continent, Hunter says.
In addition, the cheetah has been driven out of 91 percent of its historic range ” the big cats once roamed nearly all of Africa and much of Asia, but their population is now confined predominantly to six African countries: Angola, Namibia, Zimbabwe, Botswana, South Africa and Mozambique. The species is already almost extinct in Asia, with fewer than 50 individuals remaining in one isolated pocket of Iran.
Based on these results, the study authors are calling for the cheetah's status to be changed from"vulnerable" to"endangered" on the IUCN Red List.
"These large carnivores, when they are declining at that sort of rate, then extinction becomes a real possibility," Hunter says.
DOUBLE WHAMMY
Perhaps unsurprisingly, humans are the main reason that cheetahs are in peril.
Like other large carnivores, cheetahs face habitat loss driven by conversion of wilderness areas into managed land dedicated to agriculture or livestock. People will then sometimes kill cheetahs if they perceive the animals as a threat to their livestock, even though cheetahs rarely take domesticated animals, Hunter says.
Cheetahs are also subject to vehicle collisions and poaching for their skin and other body parts. Sometimes they're even killed for bushmeat, though that threat is mostly targeted at cheetah's prey species, such as antelopes, gazelles, impalas and warthogs. All are ideal cheetah prey, and all are heavily hunted by people in many areas, Hunter says.
"Cheetahs are facing a double whammy: They are getting killed directly, and then also their prey species are getting killed in these savanna areas, so the cheetahs have nothing to subsist on," Hunter says.
Other threats include high demand for cheetah cubs as pets, mainly in the Middle East, which results in the illegal trade of cubs from North Africa.
CONSERVATION CATALYST
Some cheetahs already live in protected areas like national parks, where it is safer and more accessible, and the animals are expected to be subjected to fewer threats, says study leader Sarah Durant of the Zoological Society of London.
But during the new assessment, Durant and her colleagues found that two-thirds of the cheetah population lives outside of these protected zones, in part because the animals need room to roam.
"We can't have any more cheetahs in protected areas ... the density is already the maximum it can be," Durant says."The key to the survival of the cheetah is its survival outside of protected areas."
The study team, led by Panthera, the Zoological Society of London and the Wildlife Conservation Society, hopes that its results will spur the IUCN to reclassify the cheetah as endangered.
It is likely too late to grow and protect the species in areas like West or Central Africa, where these big cats have long been on the decline, Hunter adds. But there is enormous potential for the population to rebound quickly in other areas.
The new conservation status would provide a platform for these groups to try and reverse the trends affecting cheetahs. For instance, such a change can create openings for funding streams that are available only to endangered species, and they might allow for conversations with African governments about cheetah conservation programmes.
"What we are really hoping," Durant says,"is this will catalyse action to start thinking outside the box for cheetah and landscape conservation, to start looking beyond the protected-area system and looking at how we can get communities engaged in and supportive of conservation, and make sure we have the policy and financial policy framework in place so that they will benefit from conservation."
