Biodiversity and Conservation Test - 7

Indian forest act 1927 defines the procedure to be followed for declaring an area to be reserved forest and also defines about the forest offences but this law do not say about government does not have any property rights.

Chilika lake is a brackish water lagoon, spread over the Puri, Khurda and Ganjam districts of Odisha state on the east coast of India, at the mouth of the Daya River, flowing into the Bay of Bengal, covering an area of over 1,100 km2. It is the largest coastal lagoon in India and Asia and the second largest lagoon in the world.

In 1981, Chilika Lake was designated the first Indian wetland of international importance under the Ramsar Convention.

In vivo conservation involves a range of actions that can be taken to ensure the survival of organism that are threatened with extinction as keeping in zoo or botanical garden. So, organisms live as well as evolve through in vivo conservation.

Ramsar convention is an inter-governmental treaty on wetlands that provide the framework for national action and international cooperation for the conservation and wise use of wetlands and their resources. It is not affiliated with the united nations systems of multilateral environmental agreements.

Ex-situ conservation is costly procedure. It allows captive breeding and preserves recalcitrant seeds. It is done inside laboratory at low temperature and controlled environmental conditions.

Evil quartet are for process that are responsible for loss of biodiversity. It includes fragmentation, overharvesting, introduction of invasive species and habitat degradation. It do not include fission.

The species that had been recently extinct includes Quagga (Africa), Steller’s Sea cow (Russia) and Dodo (Mauritius). Bengal tiger is not extinct so far.

Amphibians group of animals are more venerable to extinction. About 33% of amphibians are facing danger of extinction followed by 23% of mammals and 12% of birds species.

Habitat destruction is a major cause for biodiversity loss. Habitat loss caused by human activities like deforestation, overpopulation, pollution and global warming.

Species which are physically large and those living in forests or oceans are more affected by habitat reduction.

Habitat conservation is a management practice that seeks to conserve, protect and restore habitat areas for wild plants and animals, especially conservation reliant species, and prevent their extinction, fragmentation or reduction in range.

In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species.
