Tiger Corridors in India

These are operationalized through a Tiger Conservation Plan, mandated under section 38V of the Wildlife (Protection) Act, 1972.
A tiger corridor is a stretch of land linking tiger habitats, allowing movement of tigers, prey and other wildlife. Without corridors tiger habitat can become fragmented and tiger populations isolated leaving the tigers vulnerable to localized extinction. Corridors are used by other wildlife also.
The corridors across states are important as big cats travel long distances. Tiger travels 1,300 km in 150 days, crossing Maharashtra, Telangana, six districts, and four wildlife sanctuaries to establish its territory.
Section 38 O (1) (g) permits tiger corridor diversion with National Board for Wildlife and National Tiger Conservation Authority approval.
Further, Section 38 V (3) (b) of the said Act, provides for the tiger conservation plan to ensure ecologically compatible land uses in areas linking one protected areas or tiger reserve with another for addressing the livelihood concerns of local people, so as to provide dispersal habitats and corridor for spill over population of wild animal from the designated core areas of tiger reserves or from tiger breeding habitats with other protected areas.

What is need of conservation of Tiger corridors?

It is vital for the long-term survival and viability of tigers
Corridors are under threat from development projects.
Greatest threat: Road and railway expansion causing corridor fragmentation, leading to tiger mortality and human-animal conflicts.
India’s 2018 tiger estimation revealed 2,967 tigers, necessitating corridor mapping for enhanced conservation as they venture outside protected areas.
Need to sensitize villagers along these corridors about conservation of wildlife.
