@@Bio-cultural diversity is a concept that embraces biological diversity, cultural diversity and the important interactions between them. A bio-cultural approach to development is an opportunity to reframe the international development conversation as it lifts the voices of local and indigenous people and their cultures and creates a more resilient and beautifully diverse world. It includes all the levels of biodiversity, from species to ecosystems, and all the manifestations of cultural diversity, from ideas to cultures and including linguistic diversity. It focuses particularly on the relationships between different cultures and their natural environments.Nepal is multicultural, multilingual and multi-religious country is a good example of having rich bio-cultural diversity. Nepal covers all shades of climate from tropical to alpine and even to dry desertic in trans Himalayan, resulting in environmental diversity giving Nepals ecosystem a unique wealth and variety. With 118 ecosystem types, 75 vegetation types, and 35 forest types, it houses about 6,500 species of flowering plants, of which over 370 species are found to be endemic and around 2000 species as medicinal and aromatic plants. Even though Nepal shares only 0.1％ of the total land area of the world, it still harbours 2.7 ％ of the worlds flowering plants, 9.3％ birds, and 4.5％ of mammals of the world. This diversity is found in the dense tropical monsoon forests of the Terai, the deciduous and coniferous forests of the subtropical and temperate regions, and the sub-alpine and alpine pastures and snow covered peaks of the Himalayan mountain range.
