Nepal has been identified as one of the Asia’s most biologically important countries. The tiny country is the home of nearly 4.5 per cent of the world's mammalian species and over nine per cent of bird species.The country with its wide range of altitude and immense bio-climatic diversity supports more than thirty- five forest types giving rise to 5,833 species of flowering plants, including around 248 species of endemic plant and 700 species of medicinal plants. Nepal's landmass is also home to 185 species of mammals, 847 species of birds, 645 species of butterflies, 170 species of fishes and other animals. At this time, 26 species of mammals, nine species of birds and three species of reptiles are declared endangered.
18% of the total area of Nepal is set aside as national park or wild life conservation areas the largest figure declared for conservation in any country. There are currently 8 national parks, 4 wildlife reserve, 3 conservation areas and one hunting reserve .
Uniqueness of Nepal becomes transparent through the prism of its diverse biogeography, ranging from the warm sub-tropical forests of Chitwan National park to the breathtaking beauty of Sagarmatha (Mt. Everest) National Park which includes the highest peak of the world and a vast unfurling range of summits of the Northern Himalayan region.
The chief aims of the National parks and Reserves are, primarily, to ensure the conservation and management of the natural resources and environment, including the flora and fauna as well as their habitats, and secondly, to develop and promote nature and wild life tourism, where suitable in such areas possessing tourist attractions, so long as these activities are not detrimental to the implementation of conservation programmes. Nepal has so far succeeded in drawing appreciably increasing numbers of foreign and regional tourists every year and it is evident that there is tremendous potential of the national parks and the reserves for future expansion of nature, wild life and jungle adventure holiday tourism.
National parks now a days are gaining increasing importance as one of the most sought after tourist attractions in the world and in recent years have made major contribution in the spectacular growth of tourism in Nepal. Numerous accommodation facilities hotels, wild life camps and cafeterias have mushroomed in the park areas to cater to the increasing volume of visitors.
