Boranical gardens helps in conservation of plants by
(i) Growing important local plant species and keeping record of them.
(ii) Growing and maintaining rare and endangered species.
(iii) Supplying seeds for different aspects of botanical research.
Whereas zoological parks also contribute in conserving biodiversity by
(i) Providing natural environment and open space to animals, i.e., wild life species.
(ii) Keeping them safe from their predators ensuring protection, food and shelter.
(iii) Providing home to different native and exotic wild anials.
