To conserve the representative ecosystems, a Biosphere Reserve program is being implemented. Ten biodiversity rich areas of the country have been designated as Biosphere Reserves applying the UNESCO/MAB criteria. These reserves aim at conserving the biological diversity and genetic integrity of plants, animals and microorganisms in their totality as part of the natural ecosystems, so as to ensure their self-perpetuation and unhindered evolution of the living resources. India has a vast protected area network, which also includes the Biosphere Reserves.
