Nepal occupies approximately 0.001% of total land of the earth and 0.01% of Asia, and extends along the Himalayan range between the latitudes 26°22′ – 30°27′ and longitudes 80°04′ – 88°12′ with great altitudinal variation that ranges from less than 60m in the lowland of Terai in the South to the crest of the Himalaya reaching 8848m in the North. Due to such advanced altitudinal variations and geographical locations, Nepal is one of the riches countries in terms of biodiversity wealth where over 5,000 species of non-flowering plants (807 species of algae, 2,025 species of fungi, 771 species of lichens, 1150 species of bryophytes, 534 species of Pteridophytes), 28 species of gymnosperms and 6,653 species of angiosperms or flowering plants are reported. Likewise, Nepal claims 8.5% of its bird species, 4.2% of mammals, 4.2% butterflies, 2.2% of fresh water fishes and is the home of 2.36% of the worlds’ flowering plants, at least 11 different bioclimatic zones, 118 ecosystem, 75 vegetation types and 35 forest types and 59 indigenous nationalities as identified by the government of Nepal. In terms of richness in biodiversity, Nepal occupies the 27thposition from higher in the world, and the 10thposition in Asia. The Diversity Index (DI), which is calculated on the basis of the area of the country, number of species of plants, birds and mammals, endemic species and threatened species in each category, Nepal stands 49thposition in the World.
