Which region of India is known for the unique Shola forests?

Shola forests are a unique type of tropical montane forest ecosystem found exclusively in the high-altitude regions of the Western Ghats across Tamil Nadu, Kerala, and Karnataka. This ecosystem consists of dwarf evergreen forests in valleys interspersed with grasslands on mountain slopes. Shola forests are highly biodiverse and serve as habitats for many endemic species including the Nilgiri Tahr, Lion-tailed Macaque, and Nilgiri Langur. They act as natural water sources for rivers like Cauvery, Vaigai, and Thamirabarani. These forests are protected within various National Parks and Wildlife Sanctuaries such as Silent Valley National Park, Eravikulam National Park, and Mukurthi National Park.
