The concept of hot spots in biodiversity was developed in the year 1988 by Norman Myes. According to him “hot spots are the richest and the most threatened reservoirs of plant and animal life on earth”. This concept was developed on the basis of two important consideration (i) The species which are not founds elsewhere and (ii) difference of loss of habitat.
According to this concept 25 hot spots have been identified for conservation of biodiversity. Amongst these, 15 hot spots have tropical forest in Mediterranean typed zones and the rest are present in tropics.
India has two hot spots. These are Western Ghats and Eastern Himalayas. Both of these areas are inhabited by a variety of flowering plants, reptiles, mammals, amphibian and butter flies.
