The term "biological diversity" or its conjunct form "biodiversity" is used to describe the number and variety of living organisms and ecosystems on the planet. Nepal is rich in such numbers and varieties of biological species and their living spaces. The global concern over the rapid loss of biodiversity prompted the Earth Summit to promulgate the international Convention on Biodiversity (CBD). Nepal is one of the early countries to ratify to the International Convention and the Ministry of Forests and Soil Conservation (MFSC) is the National Focal Point of CBD. The ministry has formed a National Biodiversity Unit (NBU) to facilitate and implement the CBD under the guidance of the National Biodiversity Steering Committee.

Botanically Nepal forms a transition zone between the plants of the western Himalaya (including western Asiatic and Mediterranean elements) and the eastern Himalaya (with many Sino-Japanese elements). Adding variety to the mix are Tibetan Plateau (Central Asiatic) plants from the north and humid tropical species of the lowland plains (Terai) from the Gangetic plains of India and further a field into Indochina. Central to this is the Himalayan range itself, a unique series of mountain chains formed by geologically recent mountain building events. These young massifs contribute to the diversity of plants, and have provided barriers to and corridors through which plants migrated during the ice ages.

This trek is to commence at Budhanilkantha with the purpose to be amazed with pleasant views of the central and eastern mountain ranges, heavenly views of sunrise and sunset and is good introduction to Nepalese rural life. The end point of the trek appears with two options either at Nagarkot or Dhulikhel and Namobuddha. Nagarkot, (2175m) is by far one of the most popular destination. In the clear weather the Himalaya range, stretching from Dhaulagiri in the west all the way past Everest to Kanchenjunga in the east, emerges from the darkness to greet the happy visitor with its awe inspiring majesty and beauty. Namobuddha is one of the holiest sites for Buddhist in Nepal. It is believed the ancients Buddha was born here as prince. . It is an excellent trip for those who wish to avoid a long strenuous trek or only have time for a short and easy trek.
