Conservation of Bio-diversity:

Biodiversity can be conserved by two methods as follows-


In-situ conservation:

The biotic resources are conserved in their natural or reformed ecosystem. It is an ideal method of conserving biotic resources. The system of naming and management are managerial based on national forest, natural landscape, reserved biosphere sanctuary etc.

Ex-situ Conservation:


Ex-situ conservation is a method of conserving germplasm of endangered species of living beings and their culture in the laboratory for their propagation in future. In this method, the species are conserved in a place other than their habitat, such as zoo, botanical garden. Different countries establish gene bank for the conservation of tech species. The main objective of gene bank is to conserve the rare, endangered species and going to be extinct species, which are used for different needs. The objectives of gene bank are made successful through establishment of field gene bank, seed bank and cry bank.
