There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Opposite of Panna TR, it's going to be a casestudy of what not to do during tiger relocation. Not only the man-animal conflict problem still remains, the first three tigers sent from already inbred Ranthambore stock were step-siblings, then followed by first cousins!

With the first male quickly dying & on top of more recent unnatural deaths, further misfortunes fell as ST-4 was killed by ST-6 & his replacement ST-16 (Ranthambore's T-75) soon followed him earlier this month in a complex controversy of septicemia, heatstroke & ostensible tranquilizer overdose
(You'll find in previous posts that he was too small & light for a 7-year-old, no more than 180kg. A "standard dose" for a 220kg male could kill him.)

That again leaves ST-6 as the only ruling male in Sariska (only less than 300km² of the 850km² reserve is tiger habitated) against 8 tigresses. Already all the cubs were fathered by him... Under the original tiger reintroduction program of National Tiger Conservation Authority started in 2008, around 20 tigers were to be reintroduced in Sariska Tiger Reserve. There's been 9 sent until now, with half of them dead, mostly males.

There's also an allegation, soething everybody suspects but nobody knows, is that powerful business lobbies don't want Sariska to stand up to Ranthambore. The deliberate neglect by successive governments have been too evident. Atleast the geniuses have at last had the clue to call in NTCA for review & overseeing.

The breeding problem is another mystery! They took a decade to settle down & finally started breeding.
Multiple tigresses relocated to STR did not have litters and are assumed to infertile but they breed like rats in Ranthambore, even in the human-dominated fringe areas.
Rajasthan now plans to bring 2-3 cats from Madhya Pradesh for Sariska in order to avoid inbreeding... Another folly Even the needs of a "tiger reserve" status for this isolated, fragmented forest was questioned recently. At this point they might as well ditch it & concentrate on creating the new Mukundara Hills genepool that has a future. The new viable population could use MP tigers, so could Ranthambore buffers like Kailadevi Sanctuary. Ranthambore NP has enough surplus cats for exchange, that'll benefit MP tigers' genes as well.

Associate professor at National Center for Biological Sciences, Bangalore, Uma Ramakrishnan, who studied genomes of tigers at RTR said:
Quote:We have sequenced and studied genomes of Ranthambore tigers. Our analyses suggest RTR tigers are isolated, have low genetic variation, are related to each other, and inbred. Inbreeding depression is when inbred tigers have a lower chance of survival. We (and others) do not see telltale signs of inbreeding depression yet. Further research in the coming years is needed to investigate this.

I didn't think that tigers in Sariska or Rajasthan would suffer from similar issues as their stripeless, tawny Gujarati cousins to the south (https://www.epw.in/journal/2019/22/comme...7t6CH-CHLg)! I see that Madhya Pradesh is important not just for the survival and genetic variability of the inbred Gujarati lions that are threatened by disasters such as an outbreak of the canine distemper virus (which massacred about 1,000 of their East African cousins in the Serengeti), but also for Rajasthani tigers. I wonder how many tigers are suffering from issues like this?
