The High Ranges of the Western Ghats are a lofty collection of plateaus that contain the tallest mountains in the Western Ghats. They fall in Kerala’s Idukki district but are contiguous with the Anaimalai and Palani Hills of Tamil Nadu. To their south lie the lower Cardamom Hills while in the north the Palgat Gap separates this block of mountains from the Nilgiri Hills. For the most part the High Range has been converted to sprawling tea estates with the settlement of Munnar being the focal point. The most notable protected area in the High Range is Eravikulam National Park. It contains the best-preserved and largest undisturbed shola/grasslands habitat left in the Western Ghats. The park surrounds the awesome Anai Mudi peak (2,695m), peninsular India’s highest peak south of the Himalaya. Eravikulam was established as a national park in 1978 to protect the endangered Nilgiri tahr (Hemitragus hylocrius), the endemic cloud goats of southern India. Chinnar is another notable wildlife sanctuary on the north-eastern slopes of the High Range. It hosts dry deciduous forest and has a significant population of Giant Grizzled Squirrels (Ratufa macroura). The Anaimalai Hills host one of the largest protected areas in Tamil Nadu (now called Indira Gandhi Wildlife Sanctuary) but are also home to tea plantations and several huge hydroelectric reservoirs.
