CONSERVATION STRATEGIES

In-situ (on-site) conservation includes the protection of plants and animals within their natural habitats or in protected areas. 

Biosphere Reserve   2. National Park   3. Wild Life sanctuary 

Ex-situ (off-site) conservation of plants and animals outside their natural habitats. These include botanical gardens, zoo, gene banks, seek bank, tissue culture and cryopreservation.
