Endemic species of India: Out of about 47, 000 species of plant 7000 are endemic. Most of the endemic species are restricted to Himalayas, Khasi Hills and Western Ghats. Some of the important endemic flora includes orchids and species like Sapria himalayana, Uvaria lurida, Nepenthes khasiana, Pedicularis perroter etc. Out of total 81, 000 species of animals in our country is endemic. The Western Ghats are particularly rich in amphibians (frogs, toads etc) and reptiles( Lizards, crocodiles etc). Different species of monitor lizards (Varanus), reticulated python and Indian salamander and Viviparous toad Nectophhryne are some important endemic species of our country.
Conservation of Biodiversity: Due to the immense important associated with the biodiversity it is important to maintain and conserve biodiversity on the earth system. A number of measures are now being taken the world over to conserve biodiversity including plants and wild life. Two types of conservation practices are present: 1) In Situ Conservation ( within habitat): It means conservation of biodiversity in its natural habitat and mainly done by designated the natural habitat as protected area such as Biosphere reserve, National Park, Wild life Sanctuary, Reserve Forest etc. 2) Ex Situ conservation ( Outside Habitat) : This is done by establishment of Zoos, botanical garden, gene banks, seed banks, culture collection etc. In Situ Conservation: At present we have 7 major Biosphere reserves, 80 National Park, 420 Wild life Sanctuary in our country.
Biosphere reserve: The idea of `Biosphere Reserves’ was initiated by UNESCO in 1973 -74 under its Man and Biosphere (MAB) Programme. The Indian National Man and Biosphere (MAB) Committee identifies and recommends potential sites for designation as Biosphere Reserves, following the UNESCO’s guidelines and criteria. By 25 th October 2007, fourteen Biosphere reserves have been established in India and some additional sites are under consideration. Biosphere Reserve (BR) is an international designation by UNESCO for representative parts of natural and cultural landscapes extending over large area of terrestrial or coastal/marine ecosystems or a combination thereof. BRs are thus special environments for both people and the nature and are living examples of how human beings and nature can co-exist while respecting each others’ needs. As on 12 th September, 2007 there were 507 Biosphere Reserves on World Network in 102 countries recognized by UNESCO which include Nilgiri, Sunderbans, Gulf of Mannar and Nanda Devi BRs from India.
Structure and Design of Biosphere Reserves: In order to undertake complementary activities of biodiversity conservation and development of sustainable management aspects, Biosphere Reserves are demarcated into three inter-related zones: 1) The Core Zone: The core zone is kept absolutely undisturbed. It must contain suitable habitat for numerous plant and animal species, including higher order predators and may contain centres of endemism. A core zone secures legal protection and management and research activities that do not affect natural processes and wildlife are allowed. 2) The Buffer Zone: These uses and activities include restoration, demonstration sites for enhancing value addition to the resources, limited recreation, tourism, fishing and grazing, which are permitted to reduce its effect on core zone. 3) The Transition Zone: The Transition Zone is the outermost part of a Biosphere Reserve. The activities in this zone include settlements, crop lands, managed forests and area for intensive recreation, and other economic uses characteristic of the region.
National Park: A national park is an area dedicated for the conservation of some particular species of wildlife along with its environment. Grazing of domestic animals, all private rights and forestry activities are prohibited within a national park. As of April 2007, there are 96 national parks. All national park lands encompass a combined 38, 029. 18 km², 1. 16% of India's total surface area.

Wild life Sanctuaries: These are also protected areas where killing, hunting, shooting or capturing of wildlife is prohibited except under the control of highest authority. However private ownership rights are permissible and forestry operations are also permitted to an extent that they do not affect the wild life adversely.

For the protection and conservation of certain animals there have been specific projects in our country. Example: Project Tiger, Gir Lion Project, Crocodile Breeding Project, Project Elephant, Snow Leopard project etc. Ex-situ conservation: This conservation strategy involve conserving the species outside its natural habitat in a controlled environment such as botanical garden for plants or a zoological park for animals, where there is expertise to multiply the species under artificially –managed conditions. Other majors are creating gene bank/ seed bank and using tissue culture methods to preserve important plant variety. In India, we have following important gene bank/ seed bank facilities: 1) National Bureau of Plant Genetic Resources ( NBPGR): It is located in New Delhi. In this Institution agriculture and horticultural crops and their wild relatives are preserved by cryo-preservation of seeds, pollen etc. by using liquid nitrogen at a temperature as low as -196°C. Crop variety of rice, pearl millet, Brassica, turnip, radish, tomato, onion, carrot, chilli, tobacco etc are preserved using this technique.
2) National Bureau of Animal Genetic Resources ( NBAGR): located at Karnal, Haryana. It preserves the genetic material of domesticated bovine animals. 3) National Facility for Plant Tissue Culture Repository (NFPTCR): It is for the development of a facility of conservation of varieties of crop plant/trees by tissue culture. It is a part of NBPGR.
