The mountain range is also a “Hottest Hotspot” of biodiversity, being one of eight in the world. The Western Ghats contain 39 properties that include national parks, reserve forests and wildlife sanctuaries. The mountains of the range cover an area of approximately 140000 sq. km. It is 1600 km long interrupted only by a low mountain pass called the Palakkad Pass.

The Western Ghats are extremely important from several points of view. One is its geomorphic importance. It is older than the Himalayas and is considered an ‘evolutionary ecotone’ illustrating the “Out of Africa” and the “Out of India” hypotheses. The Ghats also have a major influence on the ecological and biophysical processes on the entire peninsula of India. They also influence the monsoon weather patterns across the country. They present a classic example of the tropical monsoon system. The mountains act as a barrier to the rain-laden southwest monsoon winds in late summer in India.

Another reason for the Ghats’ significance is the enormous diversity and abundance of species of flora and fauna in this region. Many of these species are also endemic to the region. There are 4 – 5 thousand plant species here out of which 650 tree species are found. And, out of the 650 tree species, 352 are endemic.
