@Rishi @phatio @Roflcopters, the admixture of Bengal and Indochinese is very much a probability in tigers of the North East. But, studying the tigers camera trapped in Uttarakhand and other parts of himalayas and the similarities in their physique across the Himalayas, I think it’s more about altitude and temperature.
Indochinese tigers don’t occupy any regions with significant altitude difference to their lowland counterparts and they also don’t face the temperatures that these Himalayan dwelling tigers do. So, as much as I agree that there very much are indochinese or admixture of bengal and indochinese in the North East part of India, the ones occupying higher altitudes are a different subset on their own. PS @phatio, genetic analysis of those two Arunachal cubs (Ipra and Chipi) revealed that they were Bengal tigers but not of any subpopulation known.
@Rishi, are Pakke tigers considered from high himalayas or are they like Manas tigers, from the foothill of himalayas?
Personally, the tigers of high himalayas are the most fascinating ones in India simply because of their adaptations to altitude and temperature. Plus, they grow to ridiculous sizes and look like Amur-Bengal hybrids.

These are their core areas.  *This image is copyright of its original author Nameri is completely on the plains, connected to the Kaziranga landscape by the river beds. Pakke is on the foothills at the South to upto 2000m at the northern part. It is connected to Bhutan's tiger landscape that lies just west, about 70-75kms away. The landscape.

Nameri is right on the foothills while Pakke is in the lower to middle Himalayas. Exactly like the dynamic between Manas which is on the edge and Royal Manas in Bhutan which is in lower to middle Himalayas. The altitude in both these parks never exceeds 2000m and in Pakke, it’s highest at 1500m (according to park website). There are parks in Western Ghats who have a similar altitude range.

Nameri has no hills bro... It's completely flat floodplain. And that 1500 m altitude probably only includes the core. India govt officials websites are, wellwell, not very good nor accurate. Both Wiki, Kolkatabirds and travel guide says more than 2000m.
I know Nameri has no hills. That’s why I compared it to Manas which also has no hills. It’s Royal Manas and Pakke where the outer himalayas start.
And, pakke as a park seems technologically adept as they have videos on youtube and produce some digital content. Same can’t be said about other parks unfortunately.

Some DFO thinks of the idea & applies it within his/her own jurisdiction, but because every state works on its own, it is not always is replicated in the other parks.
Tiger spotted at record-high elevation in Nepal
https://www.worldwildlife.org/stories/ti...n-in-nepal DATE: April 28, 2020 AUTHOR: Whitney Kent  *This image is copyright of its original author New camera trap images reveal the highest-elevation sighting of a tiger in Nepal, captured at over 8,000 feet in a densely forested area. The images were taken by one of the 32 pairs of cameras set up in the Dadeldhura district in western Nepal as part of a month-long survey conducted by the Divisional Forestry Office and WWF Nepal. The survey built upon results from a 2017 survey conducted by the Terai Arc Landscape Program, which confirmed the presence of an individual tiger in lower elevations—1,598 feet—in Dadeldhura. Researchers were interested to verify anecdotal evidence of tiger sightings outside the Terai Arc, the only landscape known to be inhabited by tigers in Nepal, and at higher altitudes.  *This image is copyright of its original author Why is this significant? This first-ever recorded evidence of a tiger at this high of an elevation in Nepal supports the notion that high-altitude habitats may provide refuge for tigers and help connect their territory between Nepal and India. The finding also expands Nepal’s known tiger distribution from the Terai Arc Landscape, widening opportunities for potential tiger habitats including the use of high- altitude areas. More research needs to be conducted as to why tigers are using such high-altitude habitats. “We know that tigers are highly adaptable and have been documented at various altitudes in different landscapes, but in this case, it is important to find out why,” said Nilanga Jayasinghe, senior program officer for Asian Species Conservation. “These images are especially significant because they point to the importance of natural corridors that provide safe dispersal pathways between protected areas for tigers and other wildlife.” The Government of Nepal’s flagship Terai Arc Landscape Program has already restored many such connectivity bottlenecks to make the landscape functional, recognizing that main threat to wild tigers in the Terai Arc is habitat loss and fragmentation. Still, more needs to be done to ensure those landscapes stay connected in the future. What's next? Maintaining and restoring key wildlife corridors is essential to expanding tiger populations, but increasing threats from infrastructure development is fragmenting these key habitats. WWF is working with policymakers, companies, and investors to improve sustainable approaches to infrastructure planning and construction to ensure consideration is given to important wildlife passages and crossing points into protected landscapes. Sustainable infrastructure is not only beneficial to tigers and other wildlife, but also important to socio-economic growth, particularly to the rural areas and local communities, and for maintaining functional habitats, ecosystem services, and climate resilience.

Tiger reappearance in Bhutan’s Bumdeling Wildlife Sanctuary: a case for maintaining effective corridors and metapopulations
Evidence of tiger presence in BWS was initially based on an anecdotal sighting at Thiling village in Sherimuhung Geog in 2001, along with several yak predation reported upto 2003. Camera trapping in BWS after 2004, including a comprehensive National Tiger Survey (NTS) from 2014 to 2015, failed to capture any tiger images in northeastern Bhutan until now. Dissatisfied by the poor camera trapping results, sanctuary staff intensified field surveys in 2016 and a tiger pugmark was detected above Rigsumgeonpa monastery in Bumdeling Geog. It is unlikely for tigers here to have arrived from China or India given the functional extinction of the tiger in China (Qin et al. , 2015), and no recent tiger records in Tawang India adjacent to BWS, due to rampant poaching. The male tiger in BWS is more likely to have originated from populations in either Wangchuck Centennial National Park via Corridor 8, or from Phrumsengla National Park via Corridor 7.
