From the ecological point of view, which one of the following assumes importance in being a good link between the Eastern Ghats and the Western Ghats?

1. The question asks to identify an area that serves as an important ecological link between the Eastern Ghats and the Western Ghats. 2. The Sathyamangalam Tiger Reserve (STR) is located in Tamil Nadu, strategically situated at the confluence of the Eastern Ghats and the Western Ghats. 3. This location makes STR a crucial wildlife corridor, facilitating the movement of fauna, including large mammals like tigers and elephants, between the two major mountain ranges. Thus, it assumes great importance from an ecological point of view as a connecting link. 4. Nallamala Forest and Seshachalam Biosphere Reserve are part of the Eastern Ghats but do not serve as the primary connecting link to the Western Ghats. 5. Nagarhole National Park is part of the Nilgiri Biosphere Reserve within the Western Ghats, not a link between the two Ghats. 6. Therefore, Sathyamangalam Tiger Reserve is the most appropriate answer.
