Environment & Biodiversity Current Affairs MCQs

Notes:
A viral video of a Himalayan red fox near Pangong Tso in Ladakh has drawn attention, while wildlife officials warned against human interference. The Himalayan red fox is a subspecies of the red fox with the scientific name Vulpes vulpes montana. It is native to the Himalayan region across India, Nepal, Bhutan, and Tibet. In India, it is found in Jammu and Kashmir, Himachal Pradesh, Uttarakhand, Sikkim, and Arunachal Pradesh. It lives at high altitudes between 2,500 and 5,000 metres in diverse habitats. Its conservation status under the International Union for Conservation of Nature (IUCN) Red List is Least Concern.

Notes:
Bihar government approved a revised proposal to notify Kaimur Wildlife Sanctuary as a Tiger Reserve. The proposal will be sent to the National Tiger Conservation Authority (NTCA) for final clearance. Kaimur Wildlife Sanctuary is the largest sanctuary in Bihar with rich biodiversity and dense forests. It is located in Kaimur and Rohtas districts within the Kaimur Range. The area covers parts of the Kaimur Plateau and Rohtas Plateau.

Notes:
Recently, an ultra-rare leopard colour morph was documented in Vijayanagara district of Karnataka, marking the first such sighting in the state and the second in India. The leopard has been named the “Sandalwood Leopard” due to its pale reddish-pink coat resembling sandalwood. The animal is a female leopard (Panthera pardus), around seven years old, seen with a normally coloured cub. Such leopards are globally called “strawberry leopards” and are extremely rare. Globally, this colour morph has been recorded only five times, including one earlier sighting in Rajasthan in 2021.

Notes:
Ladakh’s double-humped Bactrian camels will debut at the 77th Republic Day parade, highlighting their unique heritage. Scientifically known as Camelus bactrianus, they are large even-toed ungulates called Ladakh’s “silent warriors”. They are native to Central Asia, ranging from Afghanistan to China, mainly in the Mongolian steppes and Gobi Desert. In India, small populations survive in the high-altitude cold desert of Nubra Valley, Ladakh. They are mainly herbivores and are listed as Critically Endangered by the International Union for Conservation of Nature (IUCN).

Notes:
Kerala and Tamil Nadu have started restoring habitats and strengthening monitoring of the grey slender loris. The grey slender loris, scientifically called Loris lydekkerianus, is a primate belonging to the family Loridae and is a prosimian, an ancient group of primates. It is found in southern India, mainly Karnataka, Kerala, and Tamil Nadu, and also in Sri Lanka. It lives in rainforests, dry forests, scrublands, bamboo areas, swamps, and montane cloud forests. It is listed as Near Threatened by the International Union for Conservation of Nature.

Notes:
Research at 27 test lakes in northeastern Germany showed an increase in the abundance of charophytes. Charophytes are a type of green algae found in freshwater ecosystems. Fossils of charophytes date back to the Silurian Period, about 443 million years ago. This period marked the shift of plants from water to land, and charophytes are the closest living relatives of land plants. They grow in silt, mud, peat, or sand and often colonize newly cleared areas first.

Notes:
The Union Minister for Environment, Forest and Climate Change chaired a meeting of NIRANTAR, the National Institute for Research & Application of Natural Resources to Transform, Adapt and Build Resilience. NIRANTAR is a collaborative platform of institutions under the Ministry of Environment, Forest and Climate Change (MoEFCC) aimed at strengthening coordination and cooperation. The platform is organised into four verticals that focus on research, assessment, and utilisation of natural resources, with special emphasis on bioresources. NIRANTAR seeks to promote sustainable use of bioresources to support development while ensuring ecological balance.

Notes:
The Miyawaki method is increasingly used in cities where green cover has declined over decades, and it is often seen in recent urban greening drives. It is an afforestation technique developed in the 1970s by Japanese botanist Akira Miyawaki. Trees and shrubs are planted very close together, also called the pot plantation method. Only native species are planted, creating a resilient and balanced ecosystem. Forests grow nearly 10 times faster and become very dense with high biodiversity. Recent municipal projects have used this method to convert polluted and barren urban land into green spaces, reducing pollution, improving soil, and enhancing ecological balance.

Notes:
Recently, the second rangewide survey of riverine and estuarine dolphins in India was launched from Bijnor, Uttar Pradesh under Project Dolphin. The initiative is led by the Union Ministry of Environment, Forest and Climate Change to strengthen river ecosystem conservation. The survey updates population estimates, assesses habitat conditions, and identifies emerging threats to dolphin species. It is coordinated by the Wildlife Institute of India (WII), Dehradun, with State Forest Departments and partners like WWF India, Aaranyak, and Wildlife Trust of India.

Notes:
The Tripura Forest Minister announced that the state has received over ₹57 crore for the modernisation and further development of Sepahijala Wildlife Sanctuary. Sepahijala Wildlife Sanctuary is located in the Sepahijala district of Tripura. The sanctuary includes important water bodies such as Abasarika Lake and Amrit Sagar Lake. Clouded Leopard National Park is a part of the Sepahijala Wildlife Sanctuary.
