What efforts have been taken for biodiversity conservation? Write in detail.

National parks: These are protected areas reserved exclusively for preserving the flora and fauna, landscape and buildings, i.e., the entire ecosystem, and monuments of historic importance of an area. In these areas grazing and cultivation are not permitted. There are some 92 national parks in our country. 
Wildlife Sanctuaries: These provide protection and suitable condition for wild animals to flourish. These are areas where hunting is not allowed at all. Animals which are on the verge of extinction are protected here. Private ownership rights are permitted only to such an extent that the animals are not harmed. There are about 492 Wildlife sanctuaries in our country. 
Biosphere Reserves: A biosphere reserve is a specified area in which multiple use of land is permitted to preserve the biodiversity. The reserves also preserve traditional life of people. These reserves have been set up recently by 'man and biosphere (MAB) programme of the UNESCO. There are 243 biosphere Reserves in our country which mainly conserve the biodiversity of the specific areas and provide protected areas for ecological and environmental research.
