Hotspot of Biodiversity (North-East Himalayas)

In this article we will discuss Hotspot of Biodiversity (North-East Himalayas)

North-east Himalayas

From the dense evergreen and semi-evergreen vegetation of the foothills in the Eastern. Himalaya, the character of vegetation changes at altitudes of 1525 m to 1830 m. Qaks, magnolias, laurels and birches covered with moss and ferns replace the sal, silk-cotton trees and giant bamboos of the foothills. At about 2745 m to 3660 m one enters the coniferous forest of pine, fir yew and junipers. There is undergrowth of scrubby Rhododendrons and dwarfs bamboos. Due to high humidity and much higher rainfall, lichens, mosses, orchids and other epiphytes cover the tree trunks. The animal life in the temperate region is different from the western Himalaya and is characterized by the presence of Indo Chinese fauna. The red panda, hog badgers, ferret badgers, crestless porcupines are typical species of this area. Three kinds of goat antelopes also occur in the eastern Himalaya and are relatives of the European chamois. Goral is a smaller goat antelope found throughout the tract on rugged grassy slopes and on rocky grounds near the conifers forests.
