How many cheetahs are there




















As well as providing a regional framework, these strategies also provide a framework for national conservation action planning. There are also a number of different projects established across southern and eastern Africa that are either dedicated specifically to the conservation and research of cheetah, or to the guild of large carnivores.

Many of these projects carry out important site-based conservation activities that benefit cheetah, and some also provide support for capacity development of national wildlife authorities. In Iran, the Asiatic cheetah is completely protected. AWF provides both proactive and reactive strategies to prevent human-wildlife conflict. We work with local communities to construct bomas—enclosures for livestock that protect them from big cats like cheetahs.

We also provide consolation funding to farmers who have lost livestock to carnivore predation. This allows farmers to replace lost livestock, with the assurance they will not retaliate against big cats and other carnivores. This cat is a solitary animal. Males have been seen living in coalitions, where they appear extremely tolerant of close proximity to other males.

The related members of the coalition will even take part in play and physical contact such as grooming, whereas the unrelated males will generally stick to themselves while remaining in the coalition. Like all females, there are some males who stick to themselves who do not belong to a coalition. They never stay in one place for long and are referred to as nomads. At times, a male will accompany a female for a short while after mating, but most often the female is alone with the cheetah cubs.

Mothers spend a long time teaching their young how to hunt. Small, live antelopes are brought back to cheetah cubs so they can learn to chase and catch them. It gets as close to the prey as possible; then in a burst of speed, it tries to outrun its quarry. These big cats are the fastest of all land mammals. Once the cat closes in, it knocks the prey to the ground with its paw and suffocates the animal with a bite to the neck. Once it has made a kill, it eats quickly and keeps an eye out for scavengers—lions, leopards, hyenas, vultures, and jackals will steal from this timid predator.

The majority of hunts result in failure. The historic distribution of this species is very wide. But in the s, European settlers saw these big cats as vermin to be eradicated, and populations were widely reduced. Currently, they only inhabit about 10 percent of their historic range. Their range occurs widely but is extremely sparse and fragmented in the regions they still inhabit. Cheetahs have small heads, lean bodies, long legs, and a yellowish-tan coat with distinctive black spots.

Cheetahs face extinction pressure from climate change, hunting by humans, and habitat destruction, which is reducing the size of their populations. Cheetahs' own genes also pose a challenge to their continued survival. Cheetahs have a low rate of reproductive success , meaning that as a species they are not always able to reproduce. With fewer offspring, the population can neither grow nor adapt to changes in the environment.

There are various theories concerning cheetah evolution, including a popular one holding that cheetahs descended from the same ancestor as the American puma. About 10, to 12, years ago, around the end of the last ice age, an extinction event took place that wiped out many large mammal species around the world, including the wild cheetahs of North America and Europe.

The extinction of these early cheetah species left only the Asian and African populations of cheetahs. Since then, they have faced pressure from climate change, habitat loss, and human activities. At the turn of the 19th century, more than , cheetahs are estimated to have been living in Africa, the Middle East, and elsewhere in Asia.

Today, cheetahs are found in the wild in several locations in Africa, and a tiny population of another subspecies, the Asiatic cheetah, is found in Iran.

Scientists estimate that fewer than 8, African cheetahs are living in the wild today and that there may be fewer than 50 Asian cheetahs left in the world. These data reflect an overall decline of about 50 percent in the last four decades, as well as a significant shrinkage in the historic range of the species.

Cheetahs today are heading toward extinction, though notably cheetahs have faced and overcome the threat of extinction before. Genetic analysis of wild cheetahs shows they may have survived two historical bottlenecks, events that sharply reduce the size of a population. When this happens, the few remaining individuals end up inbreeding , or mating with relatives.

Inbreeding reduces the size of the gene pool , which can lead to problems such as decreased genetic variability and the persistence of potentially harmful mutation s, making it harder for the remaining population to adapt to changes in their environment.

In a very small population, any mutations that occur are much more likely to be passed on to offspring and propagate through successive generations. The first bottleneck event that cheetahs may have undergone occurred around , years ago when cheetahs expanded their range into Asia, Europe, and Africa. This range expansion is believed to have occurred rapidly, dispersing the cheetahs over a very large area and thus restricting their ability to exchange genes. The second likely bottleneck event occurred about 10, to 12, years ago, around the end of the last ice age.

In this bottleneck the cheetahs of North America and Europe went extinct, leaving extant only the species' Asian and African populations.

As large mammals died out across the world, the number of surviving cheetahs dwindled, which caused extreme inbreeding. Even though the number of cheetahs grew to as many as , during the 19th century, their genetic variability remained low due to the extreme bottleneck event that took place thousands of years previously. Present-day cheetah populations have relatively low genetic variability, evidence for which comes from several different indicators. One way to test for the degree of inbreeding is to perform a skin graft.

This involves transplanting a piece of skin from one cheetah onto another to see if the receiving cheetah accepts or rejects the graft. In inbred populations, skin grafts are easily accepted by individuals unrelated to the donor. This occurs among cheetahs, suggesting they have lost some genetic diversity. Another sign of inbreeding is asymmetrical skull development.

In inbred animals, the skull is more asymmetrically shaped.
