The Biodiversity Heritage Sites in Odisha & their significance – N.F Times


Biodiversity Heritage Sites (BHSs) are well-defined areas having unique and fragile ecosystems in terms of biological and ecological significance.

They may spread over terrestrial, aquatic, coastal, inland and marine ecosystems having rich biodiversity.

The Biodiversity Heritage Sites are endowed with wild as well as endangered species.

Importance of Biodiversity Heritage Sites

Biodiversity is closely linked to ecological security. Loss of biodiversity and bio-resources may lead to ecological imbalance.

The biodiversity heritage site status entails long-term protection, conservation and management of species that are classified as endangered and endemic to the region.

BHS declaration marks the voluntary participation of communities in protection and conservation of biodiversity in a region.

As per Section 37 of the Biological Diversity Act, the state governments are empowered to notify areas with biodiversity importance as Biodiversity Heritage Sites.

The state governments, in consultation with local bodies as well as the Central government, may frame rules for the management and conservation of BHS.
