It is believed that the Western Ghats were formed during the breakup of the supercontinent Gondwana around 150 million years ago. The range extends from the Satpura Range in the north, stretching from Gujarat to Tamil Nadu; it extends to the states of Maharashtra, Goa, Karnataka and Kerala. The Western Ghats meet the Eastern Ghats at Nilgiris, Tamil Nadu.
The Western Ghats are one of the four watersheds of India that feed its many rivers. From here originate the Godavari, Kaveri, Krishna, Tungabhadra and Thamiraparani; there are also several famous waterfalls in the range. Various man-made lakes and reservoirs have also been built.
Though man has interfered much with the forests of the Western Ghats, they are still among the ten hottest biodiversity hotspots of the world. The government has established protected areas, biosphere reserves, national parks, forest reserves and wildlife sanctuaries in the Western Ghats.
