WILD LIFE SANCTUARIES It is an initiative to conserve wild life

animals. Provides opportunity for wild

animals to live in their natural habitat.

Controlled interference of man without harming the environment and free life of animals.

No kind of human intervention is allowed. All organisms are given opportunities to

live as part of nature. They are rich storehouses of biological

wealth. E.g. Eravikulam and silent valley

BIOSPHERE RESERVES They are replicas of the biosphere. These include many national park and

wild life sanctuaries. No human activities is allowed in the

core zone of it . The buffer zone around the core zone

will contain many natural resources. These resources can be utilized for
