Manaslu is the eighth highest mountain in the world at 8,163 metres (26,781 ft) above sea level. It is located in the Mansiri Himal, part of the Nepalese Himalayas, in the west-central part of Nepal. Its name, which means "mountain of the spirit", comes from the Sanskrit word manasa, meaning "intellect" or "soul". Manaslu was first climbed on May 9, 1956 by Toshio Imanishi and Gyalzen Norbu, members of a Japanese expedition. The mountain's long ridges and valley glaciers offer feasible approaches from all directions, and culminate in a peak that towers steeply above its surrounding landscape, and is a dominant feature when viewed from afar. Unlike many other regions, this valley is a sanctuary to many highly endangered animals, including snow leopards, red pandas, lynxes, Asian black bears and grey wolves. Over 110 species of birds, 33 mammals, 11 butterflies and 3 reptiles have been recorded. Conservation of wild life in the area has been achieved by monks of the monasteries in the area by putting a hunting ban in place. This action has helped the wildlife to prosper.
