Smooth-coated otter sighted for first time in Krishna sanctuary

Smooth-coated otter was sighted for the first time in the mangrove forest near the Krishna wildlife sanctuary (KWS) in Krishna district, Andhra Pradesh.

In all, seven otters were sighted in the mangrove forests and brackish water channels of Eelachetladibba and Lankevennedibba and other areas outside the KWS. The presence of the otter is a key indicator for rise of the mangrove cover in the KWS.

Okha-Kanalus, Porbandar-Wansjaliya sections of Gujarat become Green Train Corridors

The Union Ministry of Railways has declared the Okha-Kanalus and the Porbandar-Wansjaliya railway sections of Gujarat as Green Train Corridors.

All trains passing on these 175-km long lines (141-km-long Okha-Kanalus route and the 34-km-long Porbandar-Wansjaliya route) are now equipped with bio-toilets.

On these routes, about 29 trains consisting of nearly 700 coaches have been equipped with bio-toilets to prevent open discharge free zone on tracks as part of the Swachh Bharat Mission.

What are Green Train Corridors?

  • Green Train Corridors are sections of the railways which will be free of human waste discharge on the tracks. Trains running on these corridors will be equipped with bio-toilets.
  • Thus, it will completely stop discharge of human waste from trains onto the ground which in turn would help in improving cleanliness and hygiene.
  • The 114-km long Rameswaram-Manamadurai section of Tamil Nadu was made the India’s first Green Rail Corridor in July 2016

Background

The Union Ministry of Railways has taken up a mammoth task of equipping human discharge free bio-toilets in all its coaches by 2021-22 in order to contribute to mission ‘Swachh Bharat Abhiyan’. It aims at completely stopping discharge of human waste from trains onto the ground in order improving cleanliness and hygiene

What are Biotoilets?

  • The environment-friendly bio-toilets for passenger coaches were developed jointly by Indian Railways and Defence Research and Development Organisation (DRDO).
  • In the bio-toilet fitted coaches, human waste is collected in biodigester tanks below the toilets and is decomposed by a consortium of anaerobic bacteria.
  • By the process of hydrolysis, acetogenesis, acidogenesis and methanogenesis, the anaerobic bacteria converts human faecal matter into water and small amount of gases (including methane).

IUNC to declare Kashmir’s Red Stag as Critically Endangered

The International Union for Conservation of Nature (IUCN) is going to declare the Kashmiri Red Stag (also known as Hangul) as a Critically Endangered species.

The critically endangered status to the Kashmiri Red Stag will help it to get more protection and enhance the conservation efforts to increase its rapidly declining population.

About Kashmiri Red Stag

  • The Kashmir Stag or Hangul is a subspecies of elk native to India.
  • Earlier it was believed that it is a subspecies of red deer. But mitochondrial DNA genetic studies have revealed that it is part of the Asian clade of elk.
  • It is found in dense riverine forests in the high valleys and mountains of Kashmir Valley and northern Chamba district of Himachal Pradesh.
  • As per Bombay Natural History Society (BNHS) nearly 3000 to 5000 Hanguls existed around the 1940s.
  • But at present, only about 150 of them survive within its last bastion in Dachigam National Park located on foothills of Zabarwan range on the outskirts of Srinagar, J&K.
  • Protection status: It has been listed under Schedule-I of the Wildlife (Protection) Act, 1972 and J&K Wildlife (Protection) Act, 1978. It also has been listed among the top 15 species of high conservation priority by the Central Government.
  • Reasons for decline in population: (i) habitat destruction, (ii) over-grazing by domestic livestock, and (iii) poaching.
