I am wondering what is the carrying capacity of Chitwan national park in Nepal. It's twice bigger than Kaziranga and hence theorethicaly could feed 4800 rhinos, but has "only" 600. I hope one day the number of rhinos in Chitwan to surpass at least 1000. Could any other protected aria in the subcontinent as Manas, Dudhwa or Bardia maintain same astronomical density of rhinos as Kaziranga national park and if not - why? Jaldapara is 50% of the territory of Kaziranga but has 12 times less rhinos... So currently the three largest populations of Greater One Horned Rhino are: 1. Kaziranga - around 2400 - 5 animals per 1 sq km 2. Chitwan - 600 - 0,7 animals per 1 sq km 3. Jaldapara - 200 - 1 rhino per 1 sq km  (11-10-2017, 04:29 PM)Wolverine Wrote: I am wondering what is the carrying capacity of Chitwan national park in Nepal.

Kaziranga, Indian Manas & Dudhwa had high percentage of grassland. Gorumara, Jaldapara & Chitwan have lot of dense forests interspersed with grasslands...
That's why I think Manas is a potential rhino super-power.
Yes, percentage of forests in Chitwan is probably much higher than in Kaziranga. Nevertheless hope one day number of rhinos there to surpass at least 1000. And also probably the soil around Brahmaputra river (Kaziranga) is more fertile than the soils in any other park. 
Huge tusker roaming in SouthWest Bengal town..

Corbett has wild elephants but doesn't have gaurs, Kanha has gaurs but doesn't have wild elephants as long as I know. Why Indian biologists do not introduce elephants in Kanha? An ideal Indian jungle should posses both elephant and tiger, Hathi and Sher Chan... as we know from "Jungle book". 
It may be due to poaching by man in kanha some elephant poaching mafia will be there. Or there are no preferred vegetation types for elephants in kanha. The bigger tigers in Corbett besides being overpopulated there should have targeted gaurs immensely that may have lead to their extermination.

Gaurs originated in the East & are still in the middle of their natural westward expansion. Kanha & the similar landscapes haven't had elephants for many years, & it was a natural extinction. They were once found as west as Syria... The forests became too dry about the same time Sahara started expanding about 5k years ago & Asian elephants need water more than African ones do (so.. no desert elephants). By Alexander's time their range have retreated to North-Indian plains. Terai is a much wetter habitat with lots of most-undergrowth are important to support elephants. The eastern parts of Central India, like Orissa, Jharkhand have them. However, the have been recent reports of elephant here's migrating as west as Guru-Ghasidas Tiger Reserve of Chhattisgarh from the Chhotanagpur Plateau. Also, elephants from Nilgiris have been paying visits to the Southern hills of Eastern Ghats after 200 long years of absence (Man-Elephant Conflict and Mitigation - Koundinya Wildlife Sanctuary, Andhra Pradesh). PS: Species aren't just introduced from one forest to another just because "..An ideal Indian jungle should posses both elephant and tiger, Hathi and Sher-Khan". C'mon, be sensible...

So basically what you want to say is that the forests of Central India currently are too dry for Asiatic elephants.
I once read a news that Indian rhino population once was only around 12. I was worried that time that all individuals that survived must have been inbred. But surprisingly NO. That estimate must have been wrong or those 12 or odd surviving rhinos must have been like one individual each from different diverse populations. Whatever has happened to my surprise Indian rhinos in kaziranga have the highest genetic diversity among Indian rhino population elsewhere. Here is the proof from the research that has been conducted.

As we know the action in Kipling's fiction-novel "Jungle Book" (1894) took part exactly in this aria (not far from Seoni, MP) and according to novel "Hathi", the wild elephant was presented there at those times. So know when the foreign tourists visit Kanha or Pench national parks they expect to see Hathi, but they are bit disappointed.... Nevertheless Kanha national park is no doubt one of the most brilliant and remarkable parks in all Asia with probably widest variety of hoofed and carnivorous mammals in all the subcontinent. |
