Q and A about why we MUST be clear about Cheetahs
Can you explain briefly why we need to save cheetah
Cheetah as a species survived a genetic bottleneck approximately 12,000 years ago, when only a few thousands individuals were left in the world. Cheetah recovered in numbers, and in the beginning of 20th Century there were around 100,000 animals in Africa and Asia. Growth of human population, its activities and expanding their territories led to the drastically declining of cheetahs in the wild. Today the known cheetah population is only 6,700 (IUCN Red List, 2015) and estimated to be not more than 10,000! Such a rate of declining could lead to the total extinction of the species in the next 50 years. Saving the cheetah for posterity – is protecting its environment by working with local communities, stakeholders and authorities, as well as with international organizations and people.
When the big crash in numbers happen?
There were several crushes in wildlife numbers. The global climate changes took place at different times leading to a periodicextinction of countless species. By the beginning of the Pliocene (about 5 million years ago) in Europe, 13% of families of terrestrial mammals has disappeared. At that time, the order Carnivora lost 12 of the hyena species and 6 species of felines. During the last 1.6 million years, in the northern hemisphere at least 4 times glaciers moved from low to high latitudes causing massive extinction of animals. It is known, that 20 000 years ago, ancient cheetahs were widely spread throughout the world inhabiting the vast areas ofAfrica, Asia, Europe, India and even North America. The last glaciation of the northern hemisphere at the end of the Pleistocene(about 10 000-12 000 years ago), the Earth’s climate has changed dramatically, which resulted in the disappearance of various animal species. In North America, Europe and Asia 75% of species vanished and among them, saber-toothed cats, lion and American Miracinonyx – the ancestor of a modern cheetah and puma. At the end of the glaciation, cheetah (Acinonyx jubatus) disappeared from East Asia. Only small number of cheetahs survive that are the ancestors of all the currently existing cheetahs. The species has passed through the so-called genetic “bottleneck”, which resulted in inbreeding. However, cheetah population has recovered and now three subspecies have been genetically confirmed, out of which two subspecies are found in Africa (Acinonyx jubatus jubatus andAcinonyx jubatus soemmeringii) and one in Asia (A.j. venaticus), which is the last Asiatic cheetah which survived in Iran in a very low numbers (about 120 animals).
What NOT to do when one sees/hears cheetah
While observing animals in the wild it is very important to remember that we all are guests in their world and have to respect the privacy of with animals. Therefore:
