The Asiatic Cheetah, also known as the Iranian Cheetah, is a subspecies of cheetah that was once found in various parts of Asia, including India. However, due to various factors such as habitat loss, poaching, and declining prey populations, the Asiatic Cheetah population in India has significantly declined over the years. Currently, it is believed to be extinct in India.

Explanation:
The correct answer is option 'D' - in 1952. Here's an explanation of why this is the correct answer:

1. The decline of the Asiatic Cheetah in India:
- The Asiatic Cheetah population in India started declining due to habitat loss and fragmentation caused by human activities such as agriculture, urbanization, and infrastructure development.
- As their natural habitat disappeared, the cheetahs had to compete with humans for land and resources.
- Additionally, the decline in prey populations, such as deer and antelope, further contributed to the cheetah's decline in India.

2. Conservation efforts:
- Recognizing the declining population of Asiatic Cheetahs, efforts were made to conserve the species.
- In 1972, the Indian government implemented the Wildlife Protection Act to protect endangered species, including the cheetah.
- However, despite these efforts, the cheetah population continued to decline, and by 1952, it was declared extinct in India.

3. Conservation measures in Iran:
- While the Asiatic Cheetah is extinct in India, small populations still exist in Iran.
- The Iranian government has taken significant steps to conserve the remaining cheetah population, including establishing protected areas and implementing conservation programs.
- Efforts are also being made to reintroduce cheetahs into their former range in Iran.

In conclusion, the Asiatic Cheetah was declared extinct in India in 1952. The decline of the cheetah population in India can be attributed to habitat loss, poaching, and declining prey populations. While the cheetah is extinct in India, conservation efforts are ongoing in Iran to protect and restore the remaining population.

Declaration of Asiatic Cheetah Extinction in India
The Asiatic Cheetah, also known as the Iranian Cheetah, is a critically endangered subspecies of cheetah that was once found in various regions including India. However, it has been declared extinct in India. The exact year of its declaration varies in different sources, but it is generally recognized to have been declared extinct in India in the early 1950s.
Here is a detailed explanation of the timeline leading to the declaration of Asiatic Cheetah extinction in India:
1. Decline in Population:
- The Asiatic Cheetah population in India had been decreasing due to various factors such as habitat loss, hunting, and fragmentation.
- By the mid-20th century, the cheetah population in India had become critically low.
2. Last Sightings:
- The last confirmed sighting of an Asiatic Cheetah in India was reported in 1947 in the Chhattisgarh region.
- After this sighting, there were no further confirmed sightings or evidence of the presence of Asiatic Cheetahs in India.
3. Extinction Declaration:
- Based on the lack of sightings and evidence, wildlife experts and conservationists concluded that the Asiatic Cheetah had become extinct in India.
- The exact year of the declaration varies, with some sources stating 1952 and others suggesting the early 1950s.
It is important to note that while the Asiatic Cheetah is extinct in India, small populations of this subspecies still exist in Iran. Conservation efforts are ongoing to protect and increase the population of Asiatic Cheetahs in their remaining range.
