Environment & Biodiversity Current Affairs MCQs

Notes:
A recent report by the Wildlife Justice Commission (WJC) says global trafficking of pangolin scales has dropped sharply since 2020 due to COVID-19 disruptions, strong law enforcement, and changing smuggling methods. Pangolins are insect-eating mammals found in tropical forests, grasslands, and farms, often near people. There are 8 species of pangolins — 4 in Africa and 4 in Asia, including the Indian pangolin found in India, Nepal, Sri Lanka, and Bangladesh. They eat ants and termites, helping control pests and improve soil, which supports healthy ecosystems. Pangolins are hunted for their meat and scales used in traditional medicine. The Indian pangolin is listed as Endangered and the Chinese pangolin as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List.

Notes:
Public trespassing in the ecologically sensitive Bhimgad Wildlife Sanctuary (BWS) in Khanapur taluk has raised major concerns among conservationists recently. Bhimgad Wildlife Sanctuary is located in the Western Ghats in the Belgaum district of Karnataka. It was declared a wildlife sanctuary in December 2011 to protect its rich biodiversity. The sanctuary is named after the historic Bhimgad Fort, built by Shivaji Maharaj in the 17th century to defend against Portuguese forces. It borders Dandeli Wildlife Sanctuary, Bhagwan Mahaveer Sanctuary, Mollem National Park, Netravali Wildlife Sanctuary, and Mhadei Wildlife Sanctuary.

Notes:
Rajaji National Park has abundant reservoirs and water holes that help limit elephant movement into human-populated areas. The park is located in Uttarakhand, spanning three districts: Haridwar, Dehradun, and Pauri Garhwal. It lies along the hills and foothills of the Shiwalik ranges, representing the Shiwalik ecosystem. In 1983, Rajaji Wildlife Sanctuary was merged with Motichur and Chilla sanctuaries to form Rajaji National Park. The park is named after the famous freedom fighter, Rajgopalachari, also known as “Rajaji.” Situated at the transition zone between the temperate western Himalaya and the central Himalaya, it boasts rich species diversity.

Notes:
In a recent case of man-animal conflict, four people were injured in a bear attack while collecting tendu leaves in the Kawardha range of Bhoramdeo Wildlife Sanctuary. Bhoramdeo Wildlife Sanctuary is located in Kawardha district of Chhattisgarh and is part of the Maikal range in the Satpura hills. It is named after the nearby Bhoramdeo Temple, which is over a thousand years old and called the “Khajuraho of Chhattisgarh.” The sanctuary spans about 352 square kilometres and lies within the Kanha-Achanakmar Corridor connecting two major protected areas. Its landscape includes hilly terrain, dense forests, and many streams. The Fen and Sankari rivers originate here. The forest types include tropical moist and dry deciduous forests with trees like Saaj, Sal, Tendu, and Nilgiri.

Notes:
Glaciologists and local communities recently mourned the loss of Nepal’s Yala Glacier, now believed to be the first glacier in Nepal to be declared “dead.” Yala Glacier is located in Langtang National Park in Nepal’s Himalayan region. It lies at an altitude of around 5,000 meters above sea level. It is a small plateau glacier, commonly used for training in glaciological studies and mountaineering. Since the 1970s, the glacier has shrunk by 66% and retreated by 784 meters. Scientists expect it to disappear completely by 2040 due to climate change and rising global temperatures.

Notes:
The Blyde Rondavel Flat Gecko was rediscovered in the Blyde River Canyon, Mpumalanga Province, South Africa, after being unseen for 34 years. This flat-bodied lizard grows up to 8–9 cm and is adapted to live on cliffs and rocky outcrops, making it hard to spot. It was first discovered in 1991, but no sightings since then led to fears of extinction or doubts about it being a distinct species. The International Union for Conservation of Nature (IUCN) had listed it as “Data Deficient” due to lack of data. The Endangered Wildlife Trust (EWT) confirmed its rediscovery during a special expedition to a remote rocky area. This gecko is the fifth lost species rediscovered by the Endangered Wildlife Trust in recent years, after a dune mole, a butterfly, a lizard, and a frog.

Notes:
Recent camera trap images from Udanti Sitanadi Tiger Reserve (USTR) in Chhattisgarh show a positive rise in wildlife activity with carnivores, herbivores, and omnivores using the forest widely. USTR is located in the Gariaband and Dhamtari districts of Chhattisgarh. It was formed by merging Sitanadi and Udanti Wildlife Sanctuaries. The main river in the reserve is the Mahanadi, along with Udanti, Sitanadi, Indravan, and Pairi Rivers as tributaries. The reserve connects with forests of Kanker and North Kondagaon, forming a corridor to Indravati Tiger Reserve in Bastar.

Notes:
The Uttarakhand Forest Department has set up the state’s first Cycad Garden at Haldwani. The garden covers about 0.75 hectare and showcases 31 cycad species, 17 of which are threatened. It includes 9 species native to India, like Cycas andamanica, Cycas beddomei, and Cycas circinalis. The project is funded by the Japan International Cooperation Agency (JICA). Cycads are ancient plants from the Mesozoic era and are called “living fossils.” They grow slowly, reproduce less, and are vulnerable to habitat loss. They are ecologically important and fix nitrogen through symbiosis with cyanobacteria in their roots. This garden aims to support research, conservation, and public awareness.

Notes:
Scientists recently discovered a new species of damselfly called Caliphaea sinuofurcata in Arunachal Pradesh. It was found during biodiversity surveys in the Upper Siang and Lower Dibang Valley districts. The species is proposed to be named the “Bearded Bronzeback” due to its unique appearance. This is only the second species of the genus Caliphaea ever recorded in India. The first species, Caliphaea confusa, was documented more than 165 years ago. The genus Caliphaea is usually found in Southeast Asia and China, making this a significant discovery for Indian biodiversity.

Notes:
A new genus and species of eusauropod dinosaur named Jinchuanloong niedu was recently discovered from a fossilized partial skeleton with a nearly complete skull in Gansu province, China. Jinchuanloong niedu is an early member of Eusauropoda, a group of long-necked, herbivorous, four-legged dinosaurs. Its fossil was found in the lower Xinhe Formation near Jinchang city, dating back to the Middle Jurassic period, about 165 million years ago. Sauropods are known for their large size, long necks and tails, four legs, and plant-based diet. They were the largest land animals ever and lived from the Early Jurassic to Late Cretaceous worldwide. After a global warming event in the late Early Jurassic, eusauropods became the only surviving sauropod lineage.
