Environment & Biodiversity Current Affairs MCQs

Notes:
The western tragopan (Tragopan melanocephalus) is one of India’s rarest pheasants and the state bird of Himachal Pradesh, now surviving in small, fragmented pockets in Jammu & Kashmir, Himachal Pradesh, and Uttarakhand. IUCN estimates 3,000-9,500 mature tragopans remain, all in a single subpopulation, with a quarter in western Himalayas and northern Pakistan. Sarahan Pheasantry initiated the world’s first successful captive breeding programme in 2005; 43 captive-born birds recorded between 2007-2015. Captive breeding complements but cannot replace habitat protection, which is essential for species survival.

Notes:
India’s resolution on “Strengthening the Global Management of Wildfires” was adopted at the 7th Session of the United Nations Environment Assembly (UNEA-7) in Nairobi, Kenya. The resolution received wide support from UN Member States, emphasizing global recognition of wildfire threats. India highlighted that wildfires are a pressing global environmental challenge, increasing in number, scale, and intensity beyond seasonal patterns. The resolution aims to enhance international cooperation and coordinated action for wildfire management. India referenced UNEP’s report “Spreading Like Wildfire”, warning wildfires could rise by 14% by 2030, 30% by 2050, and 50% by 2100 if trends continue.

Notes:
A new species of snakehead fish has been discovered and named Channa bhoi. It was found in a small mountain stream near Iewmawlong village in the Ri-Bhoi district of Meghalaya. The species is named to honour the indigenous Bhoi community of the Khasi tribe living in Ri-Bhoi. It belongs to the Gachua group of snakehead fishes, a group rich in species diversity in the Eastern Himalayan region.

Notes:
Lantana camara is a highly invasive, strongly scented flowering shrub that has spread across millions of hectares in tropical, subtropical and warm temperate regions across the world. It is an invasive alien plant species, originally native to Central and South America, where it grew naturally as a harmless ornamental shrub. Due to failed control efforts worldwide, the IUCN declared Lantana camara one of the world’s worst invasive species in 2000. Climate change and global warming are accelerating its spread, although some local communities now use its woody stems for furniture and handicrafts, converting an ecological threat into a livelihood opportunity.

Notes:
During the All India Tiger Estimation 2026 survey, the Indian giant squirrel was sighted in the Atwan region of the Pune forest division. The Indian Giant Squirrel is also known as the Malabar Giant Squirrel and is a large rodent species native to India. It belongs to the category of tree squirrels and is adapted to living in forest canopies. It is among the largest squirrel species found in the world. The species is mainly distributed across the Western Ghats, Eastern Ghats, and the Satpura Range. It is the state animal of Maharashtra and is locally known as Shekru.

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 Delhi government stated that more than 6,500 monkeys rescued by civic bodies from residential and commercial areas were shifted to Asola-Bhatti Wildlife Sanctuary in the last five years. Asola-Bhatti Wildlife Sanctuary covers about 32.71 square kilometres on the Southern Delhi Ridge of the Aravalli hill range along the Delhi–Haryana border. It extends across southern Delhi and parts of Faridabad and Gurugram districts of Haryana. The sanctuary is part of the Northern Aravalli Leopard Wildlife Corridor.

Notes:
A forest fire recently spread inside Pangolakha Wildlife Sanctuary along the Indo-China border at about 13,000 feet altitude in Sikkim. The sanctuary is located in eastern Sikkim and is connected to the forests of Bhutan and Neora Valley National Park in West Bengal. The Pangolakha Range below the Chola Range forms a natural boundary between Sikkim and Bhutan. It has alpine, temperate, and subtropical vegetation zones.

Notes:
A recent faunal survey in Karimpuzha Wildlife Sanctuary has greatly increased biodiversity records of Kerala’s youngest protected area. The sanctuary is located in Malappuram district of Kerala on the western slopes of the Nilgiris. Its name comes from the Karimpuzha River, a tributary of the Chaliyar River. The forest forms part of the Nilgiri Biosphere Reserve (NBR) and the Nilambur Elephant Reserve (ER). It borders Mukurthi National Park (Tamil Nadu) and Silent Valley National Park (Kerala).

Notes:
Nalsarovar Bird Sanctuary recorded over five lakh birds of about 200 species in the latest census, showing a 21% rise from 4.12 lakh birds in 2024. The increase is mainly due to no boating, reduced tourist movement, and very low noise pollution over the last two years. It is located around 64 kilometres west of Ahmedabad in Gujarat. “Nal Sarovar” means Tap Lake and it is a natural shallow lake with muddy lagoons and 36 small islets.
