Don't be Surprised if You See Cheetahs in India in the Future!

Cheetah

The cheetah once ranged from the vast windswept plains of Africa to the harsh and arid desert landscapes of Arabia, Iran and neighboring countries, and India. In its historic Asian homelands, this majestic cat was kept as a companion of the royalty who used it to hunt fast game. But as time passed, the cheetah began to vanish into extinction due to wide-scale hunting throughout the regions of Western and southern Asia leaving only small populations confined to Iran. In India, the cheetah had become extinct since 1947. But now, after seventy years of extinction, the cat might be on the path of making a comeback. This was seen in recent news, when, the Supreme Court of India announced that Africa's cheetahs could be introduced in a "carefully chosen location." The court further added that the cheetah would have to be introduced on an experimental basis to see if it can adapt to India's conditions. The decision was lauded by former environment minister of India Jairam Ramesh, who had launched the movement a decade ago.

For more than ten years, cheetah experts, wildlife officials, and conservationists from all around the world had discussed the reintroduction of the cheetah to India. Although they agreed that there was a strong case for it, leading conservationists were afraid that in its hurry to bring the cheetah back, India would end up housing the cats in semi-captive conditions in secured open-air zoos instead of letting them live free. They further added that possible cheetah populations cannot be established without the restoration of prey base and habitat, and the high possibilities of a man-animal conflict. They even pointed to India's inconsistent record of reintroducing animals in the wild. One such example was the reintroduction of Asiatic lions in Chandra Prabha Wildlife Sanctuary in northern Uttar Pradesh during the late 1950s. Although the experiment was successful with lion numbers increasing from three to eleven in 1969, the selected area was not large enough and the animals subsequently disappeared. However, conservationists who had led the cheetah reintroduction initiative insisted that these doubts are baseless and stated that a decision will only take place after the chosen sites are fully analyzed for prey, habitat, and possibility of man-animal conflict.

I really admire this decision made by the Supreme Court of India. It clearly implies that in order to reintroduce an animal into the wild, the first step would be carry out experimental trials to see how well the animal can adapt to a new environment. In addition to that, it is equally crucial to thoroughly examine a potential release site for factors such as habitat and prey base, and the possibility of human-wildlife conflict. In that regard, here are some issues that any wildlife enthusiast would be interested in knowing to gauge the success of this experiment:
  1. How many African cheetahs will be reintroduced in India on experimental basis?
  2. Which sites have been selected for the reintroduction effort?
  3. How will the cheetahs be monitored during the experiment? Radio collars?
  4. What techniques would be implemented in determining the area size of the release site, prey base, and the potential of human-wildlife conflict?
  5. What native wildlife will the cheetahs be sharing their habitat with?
  6.  How will the cheetahs be protected from poachers and other anthropogenic threats?
  7.  Which agencies will be involved in conducting this experimental introduction and overseeing it?
  8. Will this project have public support?     
Since Africa's cheetahs number around 7,100 animals in the world, they have been chosen as likely candidates for India's cheetah reintroduction project. Asiatic cheetahs, which were once found in India and Western Asia, number only about fifty animals; all residing in Iran. When India asked Iran to lend some of its cheetahs as part of the reintroduction effort, the answer was "no" and now since Iran's cheetah numbers are critically low, it is best not to risk bringing any cheetahs to India from Iran. I think it is very important that the above questions should be addressed in order to give the global community some idea on how India's cheetah reintroduction project is being executed. This way everyone would know about the cheetah reintroduction experiment is progressing. But overall, this initiative sounds very good for the Indian wildlife in general and "Indianized" cheetahs in particular.

Is the Chinese Paddlefish Officially Extinct?

Chinese paddlefish

The year 2020 has begun with a very devastating news that the Chinese paddlefish has reportedly become extinct, according to a study in the journal Science of The Total Environment. Researchers who carried out a year-long survey of China's Yangtze River, in which they spotted more than 330 species of fish, did not identify a single paddlefish. The study also indicated that they could not find any of 140 fish species usually found in the river, and most are considered highly endangered. The last live Chinese paddlefish specimen was recorded in 2003. Since then, it has not been seen. Based on the surveys carried out in early 1990s and 2000s, the IUCN Red List lists the Chinese paddlefish as "critically endangered" and estimated its population as less than fifty individuals in 2009. The Red List further added that despite its first-class state protected status, the fish was historically overfished for food and as a result its populations dwindled drastically during the late 1970s. In addition, it was also tremendously affected by habitat fragmentation which was seen in 1970 with the construction of the Gezhouba Dam in the middle of the Yangtze River. The dam cut China's paddlefish population in two - one half on each side - and blocked off the fish's migration route which prevented the adult individuals from swimming to the upper reaches of the river to spawn. In addition, the construction of the Three Gorges Dam in the early 1990s further decimated the paddlefish's habitat.

Although I find this news to be very devastating to the world environment, as well as the animal world, I'm at the same time doubtful of the overall conservation status of the Chinese paddlefish. I saw several reports on various major news websites, including this one (USA Today), and they all cited this recent study that the Chinese paddlefish has become extinct. This probably means that the global public is under the impression that this fish has officially vanished into history. I, on the other hand, am unsure about this. Also, some researchers have reported that the said survey was carried out in a very quick manner covering a very large research area in a comparatively short time. I tend to think (and quite hopeful) that perhaps there are some individuals of this fish still in the Yangtze River which were missed by the researchers.

I recently emailed the IUCN to confirm regarding the Chinese paddlefish's conservation status and was told that the organization updates the Red List twice each year by assessing and reassessing the conservation status of various species. The upcoming dates for 2020 regarding the assessment and reassessment of species can be found in this link. It states that the official date of update is June 2020. I would strongly advise the public to check out this link or at least wait until the given date, instead of blindly believing what the news reports say. Only when the IUCN gives its declaration will we know officially whether the Chinese paddlefish is extinct or not.
