Hotspots are those regions of rich biodiversity which have been declared sensitive due to direct or indirect interference of human activities. Norman Myers was the first to develop hot spots concept in 1988 to designate priority areas for in situ conservation. The two main criteria for determining hotspot are - number of endemic species, and degrees of threat in terms of habitat loss. Twenty five terrestrial hotspots have been identified throughout the world. Of these, three are located in India and neighbouring countries. These three hotspots are Western Ghats, Indo-Burma region and the Eastern Himalayas. Western Ghats occurs along the western coast of India extending for almost 1600km through Maharashtra, Karnataka, Tamil Nadu and Kerala to Sri Lanka and are regarded as cradle of speciation.
