Abstract

Organization Ecologically, and biologeographically, the Indian sub-continent is one of the most fascinating regions in the world. The subcontinent of India may be taken to extend from Baluchistan, and parts of Eastern Afghanisthan in the North west, through Gilgit, Ladakh, Kashmir, Nepal, Sikkim, Bhutan to the Burma border, including the entire Pakistan, India Bangladesh Ceylon. Defined this at the region stretches from 60 E to 100 E longitude and 6 N to 38 N latitude. Biogeographially the Indian sub-continent may be divide into two broad regions : 1) The cis gangetic region covering most of the Peninsula and 2) the trans gangetic region of Himalaya and Assam. The cis-gangetic region itself comprising of the following sub regions 1 the ganagetic plain 2 the Sahyaderis 3 the chota nagpur region and 4 the rest of peninsula, while the trans gangetic region divided into : 1 Himalayan region 2 Assam region Western Ghats Western Ghats from the river Tapi to Cape Comorin, along with the Western coastal strip is a hilly area with Peaks rising to over 8000 feet. The region receives over 100 inches of rain almost everywhere, with some areas such as Agumbe and Mahabaleshwar receiving as much as 200 to 300 inches. The Western Ghats tract has rich fauna, remarkable for the fact that some species occur only in the Ghats, and now where else in the peninsula. and for the fact that related groups occur only in the Himalayas and the Western Ghats. The rodent genus Platacanthomys is restricted to this region. Of the two species of Tahr in India, One the Nilgiri Tahr Hemitragus hylocrius occurs Nilgiri, Annamalai, Palni ranges while the Himalaynan Tahr H. jemlachius lives alone the Himalayas from Sir Panjal to Bhutan. Of the yellow throatened matens, one species, Martes gwatkinsi occurs in Coorg, Nilgiris and in Kerala while Martes flavigula and M. fiona occur in the Himalayas. The malabar Civet, Viverra megaspila occurs on the Western Ghats and in the Assam and Burma. The Western Ghats forests also rich in the other important forest mammals of the Peninsula such as Gaur, Samber and Elephant. Nilgiri Langur and Liontailed Macaque. The Western Ghats forests are also rich in birds with many not occurring anywhere else in the Peninsula, though found else where in Himalayan or Burmese regions. There are seven genera of reptiles, and five genera of amphibians that are peculiar to the Western Ghats Zoological survey of India reports.
