They sent inbred tigers to sariska, mukundra, now they do brainstorming about producing more inbred offsprings. No real effort to save tigers, all about tourism and money. In the Ranthambore tiger reserve, a popular tourist attraction in northwest India, some 62 individuals, half of them descended from one matriarch, live in genetic isolation in a 1,115 km2 area. Villages surround the reserve, and there are no other tiger populations nearby to seed new genes. Ramakrishnan and her colleagues have seen markers of inbreeding in the genomes of Ranthambore tigers6. In an unpublished study, they have detected regions of over a million base pairs of DNA without variation. In an average tiger, there are 500 variations in every million or so base pairs. If these stretches harbour deleterious alleles, the offspring could have reduced fitness, increasing the risk of local extinction, she says. https://www.nature.com/articles/d41586-019-03267-z#ref-CR6  (11-02-2019, 03:03 AM)GreenForest Wrote:(10-13-2019, 07:23 AM)Rishi Wrote: Atleast 15 Ranthambore tigers can be moved The genetic diversity issue in Rajasthan tigers definitely deserves more attention. NTCA had pointed out the lack of genetic diversity in the tigers being sent to Mukundara Hills. In 2015 the then Chief Wildlife Wardern of Rajasthan requested NTCA for permission to translocate tigers from Madhya Pradesh & Maharashtra to MHTR, but that went nowhere, probably got bogged in red-tapes. Only this June I came across a news about Rajasthan looking to bring tiger from MP instead of Ranthambore to Sariska.  *This image is copyright of its original author Wildlife experts have emphasised the need for developing tiger corridors to facilitate free movement of big cats from the Ranthambhore Tiger Reserve, where they are facing space crunch. A plan was made in 2012-13(<read) but progress has been slow due to technical difficulties & fund crunch. One towards the Mukundra Hills Tiger Reserve via Ramgarh sanctuary & another to Kuno in MP via Kailadevi buffers. The above plan of rebuilding tiger populations at Kumbhalgarh & Ramgarh while bolstering Mukundara & Sariska are part of a plan for the next decade called Vision-2030.

NTCA Rejects MP-Rajasthan Interstate Tiger Translocation
The National Tiger Conservation Authority (NTCA) has turned down Rajasthan Government’s proposal seeking translocation of two big cats from Madhya Pradesh to Sariska Tiger Reserve (STR) in Alwar, saying it has done nothing to curb “human disturbance” which negatively influenced tigers’ breeding in the protected area. The tiger watchdog has made it clear to Rajasthan that unless it addresses the “irritants” to ensure tiger conservation, the NTCA would not allow shifting of any new tiger in the STR. “Key problems like disturbance from the villagers living in the STR and acute shortage of forest staff continue to exist. There is question of allowing relocation of more tigers in the big cat habitat,” said Anup Kumar Nayak, head of the NTCA. The stinging observation came at a review meeting recently with the State officials when the NTCA, much to its annoyance found that not enough was done to ensure conducive habitat to the tigers in the protected area. There are around 26 villages in the STR spread over 1,200 sq km while staff shortage particularly forest guards is as high as 50%. Due to mismanagement & unforseen circumstances, since 2018, the reserve has lost three fully grown tigers. Presently, the tiger population in the STR is hugely skewed in favour of females — one male tiger for nine tigress. Overall, there are 16 big cats in the protected area —nine tigress, three cubs and four male tigers of which only one is in the reproduction age. Three others are sub-adults, not capable of breeding. Chief Wildlife Warden of Rajasthan Arindam Tomar said as some of the tigress are infertile, the reserve needs a tigress and a male from MP to inject fresh gene pool in the predator family. He said that inbreeding among the existing tigers in the reserve may have been resulting in ‘miscarriage’ and hence there was a need to create a fresh gene pool tigers. However, Tomar admitted that disturbance was also one of the main reasons hampering breeding among the predator. Tomar said that after the gap of three years, relocation process has initiated again. “We hope to relocate good number of villages at the earliest.” In this context, even the Wildlife Institute of India in its study “Monitoring of reintroduced tigers in Sariska Tiger Reserve, Phase 2” spanning four years since 2015, pointed out that “ruggedness and human disturbance significantly influenced the breeding and spatial dynamics of the tigers in Sarsika. While ruggedness had a positive influence, the human disturbance negatively influence tigers’ breeding.” On the basis of the study, the research team comprising of WII scientists Parag Nigam, OK Malik, Bilal Habib and K Sankar prioritized two separate blocks consisting of six villages for relocation to achieve optimum conservation success by clearting an inviolate space for tigers to breed in and for the population to recover. Under the original tiger reintroduction program of (NTCA) started in 2008, around 20 tigers were to be reintroduced in Sariska Tiger Reserve (STR). Of which 9 till date have been reintroduced in STR. Four of them -- three males and a female -- died due to various reasons such as poisoning, territorial fight, poaching, heat stroke, etc. NTCA’s refusal for shifting of big cats in the STR comes following in the wake of translocation fiasco in Odisha’s Satkosia sanctuary where a tiger died and another had to be caged because of locals’ hostilaity. “This is what happened in Odisha’s Satkosia tiger reserve where the state Government did not take the community in confidence for tiger conservation. The result was that we lost two wild tigers,” he said expressing unhappiness at the Rajasthan Government’s failure to provide conducive environment for the big cats in Sariska sancutary. Ghazala Shahabuddin of Centre for Ecology, Development & Research, Dehradun insists the "Tiger Reserve" tag should be stripped off Sariska. “STR does not have any connectivity with other protected areas (PAs),” Shahabuddin said. “Let us keep it for its other wildlife and other ecosystem values such as it being the home of Aravalli fauna and being a store house for water in the region. Out of more than 850 square kilometres, only about 200 sq km in Core Area is good habitat for tigers, tigers are roaming in this area only.” Surrounded by villages, STR is completely cut off from other forests with tigers , she added.
When two tigers are fighting in the jungle, it is commented in the news... The tiger remains present in the India's spirit.

Almost permanent tiger presence, habitat development at Ramgarh-Vishdhari
Preparations are being made to make this sanctuary a satellite tiger reserve. To build preybase in the sanctuary, more than 3 dozens of chital have been released from Delhi zoo.  *This image is copyright of its original author With increased population at home, tigers are coming from Ranthambore through the path of their ancestors, to Ramgarh Vishdhari Wildlife Sanctuary. A dozen tigers were inhabited here in the '80s. According to a report, there were about 70 tigers in Hadoti forests by the 50s. The report also mentions Ramgarh along with Mukundra region. FD intends to shift the tiger to Bundi district by the end of this fiscal-year. The occupation of tigers here is considered to be the main reason behind this. Anand Mohan, Chief Wildlife Conservator of Kota, said that at present there are tigersT-110, T-62, T-115 & T-116 have wandered in Zone No. 10 of Ranthambore. Mother of the last two, tigress T-59 had also been visiting the area. According to the information, already 2 tigers are present in the sanctuary. One of these tigers is T-115. This young tiger has been spotted around Kapren in the Chambal shore district for its new territory, while the second tiger, the T-110, has lived in the forests of Bundi before Mukundara reintroduction of T-98 from same forest. T-62 spent more than a year before moving back to Ranthambore due to absence of females. That issue is to be addressed. Complete preparations are being made to develop Bundi forests as the 4th tiger reserve in the state, even before Kumbhalgarh. A proposal had been drafted and sent to the chief wildlife warden in October week for approval. The upgrade in the status is expected to strengthen the ongoing tiger conservation efforts in the state. A total area of 1, 017 sq. km has been identified as the reserve area comprising two forest blocks of Bhilwara, territorial forest block of Bundi and Indargarh, which falls under extended buffer zone of Ranthambore Tiger Reserve (RTR). According to sources, Dabi forest area, where mining is prevalent, is also included in the tiger reserve. Earlier, sambars had been brought from Delhi to this sanctuary & grassland is being developed along the Mage river by planting native species collected from other parks. National Tiger Conservation Authority has permitted shifting of 2 tigresses from Ranthambore.
