Need for Preservation - Plants and animals occupy diverse habitats. It becomes practically impossible for a biologist to study each and every plant or animal species in its natural habitat. Hence, over the years attempts have been made to preserve the plant specie..

Management of Wild Animals - Wild life management involves protection, preservation and perpetuation of species in their natural habitats. It involves the following approaches: a) Enactment of wild life legislations to regulate hunting. b) Species preservation to prote..
