Bhutan’s two-thirds of the land area is covered by forests – one fourth being protected as national parks. Bhutan’s present King’s father  Jigme Singhe Wangchuk maintained that the at least 62% of the land should be covered with forests. Although, he has been criticized by Human Rights organizations for evicting the Bhutanese of Nepalese origin, the Bhutan King received the 2006 J. Paul Getty Award for Conservation Leadership for his three decades of work to conserve the environment. Bhutan’s diverse vegetation range from tropical forests at 200 meters to alpine grasslands at 4,000 meters. The forests are home to around 165 species of mammals, and 700 species of birds. The endangered species like the tiger, one horned rhino, golden langur, clouded leopard, hispid hare and the sloth bear live in the lush tropical lowland and hardwood forests in the south. Bhutan is currently one of the only countries in the world where the Bengal Tiger can be found in viable numbers in temperate upland forest habitats. The Golden langurs are found only in Bhutan. A yak like creature Takin is Bhutan’s national animal & the Blue Poppies are national flower. Some rare medicinal herbs like Cordyceps are found in Bhutan mountains.
