Over a 3rd of India’s wild tiger inhabitants resides exterior the 50 tiger reserves, the newest All-India Tiger Population Estimation Report has revealed. As many as 1,923 tigers or 65% the overall tiger inhabitants was discovered inside tiger reserves and the remaining have been estimated to have a spread that was largely present in neighbouring forest blocks, the govt’s report on 2018 tiger inhabitants estimation confirmed.
The 2018 examine additionally estimated 2,967 tigers in India’s forests they usually occupy practically 88,985 sq.kms of locality. In the report, the govt has described the tigers residing exterior tiger reserve boundaries as ‘tigers utilizing tiger reserves’ so as to distinguish them from ‘tigers within the tiger reserve’.

Thus, over a 3rd of India’s wild tiger inhabitants largely reside in forested patches which aren’t throughout the notified locality of a tiger reserve. The National Tiger Conservation Authority (NTCA) and Wildlife Institute of India (WII) arrived at an estimated count of such tigers primarily based on camera entice photos.
“There is always an issue of defining a number within an area that has a contiguous habitat that can potentially be used by tigers outside of tiger reserves (Tiger Reserves not having hard boundaries but embedded within larger forested areas). In such cases, tigers that are photo-captured within a reserve could potentially have their activity centres way beyond the boundaries of a tiger reserve, but visit and use the TR and thus get photo-captured,” the govt report defined.
This estimate of tigers exterior the reserves once more reinforces the significance of contiguous forest habitats, tiger corridors and sink habitats that make sure the dispersal of tigers between totally different habitats.
NTCA and WII calculated the estimated numbers and acknowledged that tiger reserves like Corbett, Dudhwa, Bandhavgarh, Pench, Tadoba, Mudumalai, Nagarhole, Bandipur and Sathyamangalam have a sizeable share of such tigers whose residence vary was largely exterior reserves however in addition they go to the tiger reserve locality.

In Corbett, an estimated 231 tigers have been discovered contained in the boundaries of the tiger reserve whereas 35 have been discovered visiting the adjoining forest blocks. While in Kanha, Madhya Pradesh, 88 tigers have been discovered inside tiger reserves and 20 have been utilized within the locality of the reserve. The Mandla forest division in MP serves as a vital hyperlink for the Kanha- Pench habitat hall and throughout the 2018 estimation; 9 particular person tigers have been recognized on this division.
“These forests act as a buffer to Kanha tiger reserve. Movement of tigers has been regularly observed between Kanha Tiger reserve and Mandla Forest Division. Hence, protection of this area becomes crucial for dispersing tigers,” the report added.
A lot of tigers roaming exterior reserves have been present in Uttarakhand, Madhya Pradesh Maharashtra, Karnataka forest divisions, stated WII’s Qamar Qureshi, a lead scientist and co-authors of the 2018 tiger inhabitants estimation report.
“Some of the forest territorial forest divisions in Uttarakhand, MP, Maharashtra and Karnataka have equal or more tigers than some tiger reserves in the country. Forest departments need to be allocated more funds for wildlife protection and conservation,” he stated.

In Maharashtra, Bramhapuri Forest Division shares lots of its tigers with Tadoba Andhari Tiger Reserve. These forests function sink habitats to dispersing tigers from Tadoba and are subsequently necessary in long run viability of the central Indian tiger inhabitants, the govt report claimed. The fact can be helpful to research man-animal battle as a few of the forest blocks are dotted with human settlements- the Brahmapuri and Chandrapur forest divisions are prime examples.
YV Jhala, lead scientist and co-author of the estimation train report stated that exercise facilities of the tigers have been mapped to find out their vary. “We tried to determine the centre of the tiger’s activity to arrive at its range. The tigers have been captured at various locations on camera traps and using the geographical coordinates we were able to determine if tigers were largely found outside the tiger reserve,” Jhala stated.
“These tigers that are found largely outside the tiger reserves are important as they ensure gene flow between two habitats and they are vital for gene exchange and survival of this species,” he added.
Independent consultants stated that this fact was encouraging and proof of performance of tiger corridors. “It is encouraging to see that nearly 1/third of tigers are exterior Protected Areas. Our camera trapping research in Maharashtra over the past 5 years additionally appear comparable figures. It will likely be good to see dispersal occasions throughout the four years estimation cycles if any such occasions have been recorded. We want increasingly proof of performance of corridors to be documented to save lots of them,’ stated Milind Pariwakam, a Wildlife Biologist with Wildlife Conservation Trust.
