Sikkim
Biodiversity of Sikkim Sikkim is almost 1/20 of the size of the Western Ghats, yet it has almost the same richness of life as the Western Ghats. There are more than 100 species each of primulas and of rhododendrons and over 900 species of orchids in the Eastern Himalayas. Flora: Sikkim is home to around 5,000 species of flowering plants, 515 rare orchids, 60 primula species, 36 rhododendron species, 11 oak varieties, 23 bamboo varieties, 16 conifer species, 362 types of ferns and ferns allies, 8 tree ferns, and over 424 medicinal plants. A variant of the Poinsettia, locally known as “Christmas Flower”, can be found in abundance in the mountainous state. The Noble Dendrobium, an orchid, is the official flower of Sikkim, while the rhododendron is the state tree. Orchids, figs, laurel, bananas, sal trees and bamboo grow in the Himalayan subtropical broadleaf forests of the lower altitudes of Sikkim. In the temperate elevations above 1,500 metres (4,900 ft) there are Eastern Himalayan broadleaf forests, where oaks, chestnuts, maples, birches, alders, and magnolias grow in large numbers, as well as Himalayan subtropical pine forests, dominated by Chir pine. Alpine-type vegetation is typically found between an altitude of 3,500 to 5,000 metres (11,500 to 16,000 ft). In lower elevations are found juniper, pine, firs, cypresses and rhododendrons from the Eastern Himalayan subalpine conifer forests. Higher up are Eastern Himalayan alpine shrub and meadows, home to a broad variety of rhododendrons and wildflowers. Fauna The red panda is the state animal of Sikkim. The fauna of Sikkim include the snow leopard, musk deer, Himalayan Tahr, red panda, Himalayan marmot, Himalayan serow, Himalayan goral, muntjac, common langur, Asian black bear, clouded leopard, marbled cat, leopard cat, dhole, Tibetan wolf, hog badger, binturong, and Himalayan jungle cat.
