Correct Answer: B

Detailed Solution

    • The Sathyamangalam Tiger Reserve is located at the meeting zone of the Eastern and Western Ghats in the Erode district of Tamil Nadu.

    • Its geographical position makes it an important ecological link and wildlife corridor between the two mountain systems.

    • It connects the wider forest landscape of the Nilgiri Biosphere Reserve in the west with the forests of the Eastern Ghats.

    • This connectivity enables tigers, Asian elephants, leopards, dholes, gaur and other wildlife to move between different protected areas.

    • Wildlife corridors maintain gene flow between separate populations and reduce the risk of inbreeding.

    • These corridors help animals move between different regions in search of food, water, breeding grounds and seasonal habitats.

    • The Nilgiri landscape containing Mudumalai, Bandipur, Nagarhole and Wayanad lies to the west and south-west of Sathyamangalam.

    • Towards the east and south-east, its forests establish connections with different forest blocks of the Eastern Ghats and the Cauvery landscape.

    • The Sathyamangalam region contains dry deciduous forests, moist deciduous forests, thorn scrub, riverine forests and grasslands.

    • The Bhavani and Moyar rivers and their tributary streams are important for the ecology and wildlife of this landscape.

    • Sathyamangalam was declared a tiger reserve in 2013.

    • Nallamala Forest forms part of the Eastern Ghats in Andhra Pradesh and Telangana and is associated with the Nagarjunsagar-Srisailam Tiger Reserve.

    • Nallamala Forest does not itself form a direct ecological link between the Western and Eastern Ghats.

    • Nagarhole National Park is located in the Western Ghats and Nilgiri landscape of Karnataka, but it is not the connecting zone between the two Ghats.

    • Seshachalam Biosphere Reserve is situated in the Seshachalam Hills of the Eastern Ghats in Andhra Pradesh and is known for endemic flora such as red sanders.

    • Seshachalam is also not the principal link between the Eastern and Western Ghats.
