    Bustard Poaching in Pakistan

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Great Indian Bustard

    Mains level: Wildlife conservation efforts

    The recent shooting of two Great Indian Bustards (GIBs) in Pakistan’s Cholistan desert has left wildlife activists in Rajasthan shocked and outraged.

    Great Indian Bustards

    • The GIB is one of the heaviest flying birds and can weigh up to 15 kg which grows up to one metre in height.
    • In July 2011, the bird was categorised as “critically endangered” by the International Union for Conservation of Nature (IUCN).
    • It is considered the flagship grassland species, representing the health of the grassland ecology.
    • For a long, conservationists have been demanding to secure this population, warning that the bird might get extinct in the coming decades.
    • It would become the first mega species to disappear from India after Cheetah in recent times.
    • Till the 1980s, about 1,500-2,000 Great Indian Bustards were spread throughout the western half of India, spanning eleven states.
    • However, with rampant hunting and declining grasslands, their population dwindled.

    Why in news?

    • The GIB, which is the state bird of Rajasthan, is considered India’s most critically endangered bird.
    • It is one of the most critically threatened species in India, with less than 150 birds left in the wild.

    Indian Rhino Vision 2020

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Indian Rhino Vision 2020

    Mains level: Not Much

    The ambitious Indian Rhino Vision 2020 (IRV 2020) came to a close with the release of two rhinos — an adult male and a female — in Assam’s Manas National Park transported from Pobitora Wildlife Sanctuary about 185 km east.

    Try this PYQ:

    Q.Recently there was a proposal to translocate some of the lions from their natural habitat in Gujarat to which one of the following sites?

    (a) Corbett National Park

    (b) Kuno Palpur Wildlife Sanctuary

    (c) Mudumalai Wildlife Sanctuary

    (d) Sariska National Park

    What is IRV 2020?

    • In 2005, conservationists, alongside the Bodoland Territorial Council and the Government of Assam, came together to develop a long-term strategy to manage the species.
    • Their vision was ambitious; to build a 3,000-strong wild population of Greater one-horned rhinos by 2020, spread across seven sites in the state of Assam.
    • Thus the “Indian Rhino Vision 2020” (IRV2020) was born.

    Success of the IRV

    • Designed in 2005, the IRV2020 is believed to have achieved its target of attaining a population of 3,000 rhinos in Assam.
    • But the plan to spread the Rhinoceros unicornis across four protected areas beyond Kaziranga National Park, Orang National Park and Pobitora could not materialise.
    • Assam had at least five rhino-bearing areas till the 1980s.
    • Manas, in focus for the near-extinction of the pygmy hog, lost the World Heritage Site tag it received in 1985 along with Kaziranga from the UNESCO.
    • The translocated rhinos helped Manas National Park get back its World Heritage Site status in 2011.

    Species in news: Hypnea Indica

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Red algae

    Mains level: Seaweeds and their significance

    Two new species of seaweed have been discovered by a group of marine biologists from the Central University of Punjab, Bathinda.

    What are the species?

    • Named Hypnea indica (after India) and Hypnea bullata (because of the blisterlike marks on its body – bullate), the seaweeds are part of the genus Hypnea or red seaweeds.
    • They grow in the intertidal regions of the coast, namely the area that is submerged during the high tide and exposed during low tides.

    Do you know?

    Red Algae have great ecological importance. They form a vital part of the food chain and are also involved in producing about 40 to 60 per cent of the total global oxygen for both terrestrial habitat and other aquatic habitats.

    Details of the genus

    • The genus Hypnea consists of calcareous, erect, branched red seaweeds.
    • While Hypnea indica was discovered Kanyakumari in Tamil Nadu, and Somnath Pathan and Sivrajpur in Gujarat, Hypnea bullata was discovered from Kanyakumari and Diu island of Daman and Diu.
    • There are 61 species of which 10 were reported in India.

    Significance for the food industry

    • Species of Hypnea contain the biomolecule carrageenan, which is widely used in the food industry.
    • As the two species have been found on the west and south-east coasts of India, it suggests good prospects for their cultivation which can be put to good use economically.
    • The extensive calcareous deposit on the body that has been observed also provides room for thought.
