Wildlife Species in News: Important Animals, Plants and Conservation Updates for UPSC

Wildlife species in news are frequently highlighted due to conservation studies, population surveys, rediscoveries, and ecological research. Understanding why certain species become newsworthy, along with their behaviour and conservation status, is important for developing awareness about biodiversity and environmental protection.

Important flora and fauna that appear in the news are often discussed along with their habitat, ecological role, and IUCN conservation status, as these aspects help explain their significance in current environmental developments. Such themes are commonly relevant in biodiversity and environment-related discussions.

Polar Bear

Polar Bears recently attracted scientific attention because researchers discovered a unique property in their fur that helps them survive harsh Arctic conditions. This finding could also inspire sustainable industrial materials.

• Reason in News: Sebum in Polar Bear fur keeps them dry and water-repellent, a potential sustainable alternative to harmful PFAS.
• Characteristics: “Sea Bears,” largest bears, are excellent swimmers. Thick, fat, and water-repellent fur (due to Sebum) aids Arctic survival.
• Habitat: Arctic regions, mainly ice-covered shallow areas.
• Ecological Role: Top predators, vital for Arctic marine ecosystem, regulating seal populations.
• Conservation Status: Vulnerable (IUCN).

Tiger Green Status Assessment

Tigers are one of the most important flagship species in global wildlife conservation. Recent assessments have evaluated not only their risk of extinction but also the progress of population recovery.

• Context: IUCN’s Red List tracks threatened species; Green Status assesses population revival.
• Reason in News: Tiger Green Status Assessment reported population increase across Asia but highlighted conservation challenges. India’s tiger population rose by 30% in two decades, contrasting with other Asian countries.
• Threats: Habitat loss, human population, declining prey, and climate change.
• Population (India): Over 3,600 wild tigers, over 75% of the global total.
• Conservation Status: Endangered (IUCN), Schedule First (WPA), Appendix First (CITES).

Asiatic Lions

Asiatic Lions are one of the most successful conservation stories in India. Recent census data has highlighted significant population growth in their only natural habitat.

• Concentration: Gujarat’s Saurashtra region, around Gir National Park.
• Population Growth: 674 (2020) to 891 (2025), a 32% increase, with the adult female population (27%) rising. Lions expand into buffer zones.
• Characteristics: Panthera leo persica are smaller than African Lions with a smaller mane.
• Conservation Status: Endangered (IUCN), Schedule First (WPA), Appendix First (CITES).

Elephants

Elephants are key ecosystem engineers and require large landscapes for survival. Regular population surveys help assess conservation progress and habitat health.

• Reason in News: The Interstate Coordination Committee conducted an elephant census in South Karnataka, Kerala, and Tamil Nadu.
• Purpose: Evaluate conservation efforts and understand population dynamics.
• Methodology: Block Sampling, Line Transect Survey, and Water Hole Count (for age/sex determination).
• Conservation Status (Asiatic Elephants): Endangered (IUCN).

Nilgiri Tahr

The Nilgiri Tahr is an endemic mountain ungulate of the Western Ghats and an important symbol of biodiversity in southern India. Population assessments are conducted to track its conservation status.
