Protection of rear species. Creating national parks and sanctuaries. Declaring some areas as reserved bio-diversity zones. Undertaking special projects to nurture specific species. To compile and document traditional knowledge. Ex. Seed bank, gene bank

Reserved Bio-diversity zones. In this area wildlife is protected but the local people are permitted to carry on with their daily life and work. A treaty for protecting plants and wild animals in danger of extinction because of international trade has come into force since 1975. this treaty regulates the import and export of all kinds of wildlife.
