Why in news?

Madhya Pradesh forest department seeks to revive the plan to reintroduce Cheetahs in Nauradehi sanctuary.

About the Plan

•   National Tiger Conservation Authority (NTCA), is nodal agency for the Cheetahs reintroduction plan.
In 2009 Project Cheetah was launched and Kuno Wildlife Sanctuary (MP) and Shahgarh area in Rajasthan were also identified as other two sites for cheetah reintroduction plan.
Nauradehi was found to be the most suitable area for the cheetahs as its forests are not very dense to restrict the fast movement of Cheetahs.

Significance of the move

It will make India the only country in the world to host six of the world's eight large cats, including lions, tigers, jaguars, panthers and leopards.
Cheetah is the flagship species of the grasslands. This will help dryland ecosystems of India to return to their natural state.

Issue Involved

Earlier plans for reintroduction of Cheetah have been stalled due to insufficient funds and inadequacy of field assessment.
Some wild life experts are on the view that the introduction of African cheetah may act as an alien species to the native ecosystem which might generate negative effects on indigenous wild life species.

Recently, Nagaland government declared the Singphan Wildlife Sanctuary as an Elephant Reserve, with the approval of central government.

About the Singhphan Elephant Reserve

It is located in Mon district of Nagaland and spreads over an area of 5825 acres.
It  has  huge  tracts  of  forest,  strategically  located  in contiguity with the Abhaypur Reserve Forest of Assam.
Presently, elephant distribution habitat in Nagaland is highly fragmented, this move will give better protection and conservation of elephants in the state.


Related Information
Status of elephant conservation;
Elephant  is  National  Heritage  Animal  and categorised as Endangered under IUCN list.
It is under schedule I of the Indian Wildlife (Protection) Act, 1972 and in Appendix I of the Convention on International Trade in Endangered Species of Flora and Fauna (CITES).
Singhbhum Elephant Reserve in Jharkhand is the first Elephant Reserve of the Country.
Karnataka has the highest number of elephants followed by Assam and Kerala respectively.
•   After the declaration it became the 30th Elephant Reserve in the country.

Union Science and Technology Minister dedicated the National   Wildlife   Genetic Resource    Bank   (NWGRB) in Hyderabad.

More on News

It  is  established  at  Laboratory  for  Conservation  of Endangered  Species (LaCONES)  and can store 17,000 vials worth of samples.
So far, genetic resources from 23 species of Indian wild animals have been collected and preserved. However, it is planned to contain genetic resources from 250 species in the beginning.


Related Information
Wildlife   Genetic   Resource   Banking (GRB)   is   a systematic collection and preservation of tissues, sperm, eggs and embryos, genetic material (DNA/RNA) of living beings.
Laboratory for Conservation of Endangered Species
It is a dedicated laboratory of the CSIR-Centre for Cellular and Molecular Biology (CCMB), Hyderabad.
It is the only institute in the country working towards conservation of endangered wildlife using modern biotechnologies to save endangered wildlife species of India.

Utility of the institute

This facility would increase the collection of genetic resources from wildlife by facilitating exchange of genetic material between Indian zoos for maintaining genetic diversity.
•   It would also facilitate research work.

Recently, World's largest 3D-printed reef installed in Maldives, for coral reefs survive due to threat posed by climate change and warming waters.

About the 3D-Printed Artificial Reef

It was developed using computer modelling and a 3D printer, which resemble reef structures typically found in the Maldives.
The reef structure is cast in ceramic, an inert material similar to the calcium carbonate found in coral reefs.
Live coral was then transplanted  within the artificial reef, where it will grow and colonize the structure.

Significance

Rising temperatures across the reefs have led to coral bleaching thus the initiative is vital to ensure the survival of marine habitats.
Traditionally,  coral  reefs  take  hundreds  of years  to form. However, given the speed of ongoing man-made habitat destruction, reefs wouldn’t have time to recover.


Related Information
What is an Artificial Reef?
It is a human made structure, similar to natural coral reef, built with the specific aim of promoting the marine life of an area.
Most   common   forms   of   artificial   reefs   are submerged shipwrecks, bridges, lighthouses, etc, which often start functioning as marine habitat after a period of time.
Similar Initiatives
In 2017, Tamil Nadu govt in collaboration with IIT Madras have been restoring Vaan Island in Gulf of Mannar by deploying artificial reefs.
What is 3D-Printing Technology?
It  is  an  additive  process  wherein  an  object  is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced horizontal cross-section of the eventual object.
Artificial reefs helps in generating marine ecosystem and boosting commercial activities by providing fishing grounds.
