The chapter on Wildlife Conservation includes detailed descriptions of several significant species such as the Turtle, Big Cat, Crocodile, Vulture, Rhino, and Dolphin. While the topic is important from an ecological perspective, it is categorized as a high-effort, low-reward area for competitive exam preparation—especially in the context of the preliminary exams.
Historically, only one or two objective-type questions are asked from this chapter in the UPSC Prelims. Therefore, aspirants are advised not to spend excessive time memorizing exhaustive details or species-specific characteristics. Instead, the focus should be strategic and efficient.
Prioritize understanding the range and distribution of the key species mentioned. Develop a basic familiarity with their habitats and link these species with National Parks, Wildlife Sanctuaries, Ramsar Sites, and Biodiversity Hotspots where they are commonly found. This interlinking approach helps in better recall and application during the exam.
To streamline your study:
Across ecosystems and continents, a variety of anthropogenic and natural threats continue to challenge the survival of numerous species. These threats often operate in combination, compounding the risks faced by already vulnerable flora and fauna. The most prevalent and concerning threats include:
Understanding and mitigating these threats is essential for any serious conservation effort, especially for critically endangered species.
Both the Gee’s Golden Langur and the Himalayan Brown Bear exemplify the ecological richness and fragility of India’s biodiversity hotspots—the Eastern Himalayas and Western Ghats. Their continued survival hinges on:
These species are not only biologically important but also serve as indicators of ecosystem health, making their conservation a national and global priority.
Among India’s lesser-known but ecologically significant species are the Hispid Hare and the Himalayan Musk Deer. Both are classified as Endangered (EN) on the IUCN Red List and are representative of the unique wildlife found in the Himalayan and sub-Himalayan ecosystems. Let’s take a closer look at their profiles:
Both the Hispid Hare and Himalayan Musk Deer serve as bioindicators of ecosystem health—one representing the endangered grassland ecosystems of the Terai and Dooars, and the other the high-altitude alpine forests of the Himalayas. Their conservation is crucial not only to maintain biodiversity but also to support the ecological integrity of their respective habitats.

Each of these species plays a vital role in maintaining ecological balance within their respective ecosystems. Conservation priorities include:
These species are not just vital to India’s natural heritage—they are also ecological indicators, keystone species, or umbrella species that help sustain entire ecosystems. Their survival ensures the survival of countless other forms of life that share their habitats.
The Vulnerable species listed above are a crucial part of India’s rich biodiversity. Protecting these species from extinction requires combined efforts in habitat conservation, anti-poaching measures, and community-based conservation programs.
Many of the Near Threatened and Vulnerable species highlighted here face growing threats from human activities such as deforestation, habitat encroachment, and poaching. However, their conservation offers an opportunity to protect entire ecosystems. Efforts must be intensified, including:
Trait | Indian Pangolin | Chinese Pangolin |
Size | Larger | Smaller |
Habitat | Terrestrial | Arboreal & terrestrial |
Distribution | All over India | NE India only |
IUCN Status | Endangered | Critically Endangered |
Common Threat: Illegal trade for their scales and meat, used in traditional medicine and luxury cuisine.
The Critically Endangered category under the IUCN Red List includes species that face an extremely high risk of extinction in the immediate future. These birds are at the brink of survival due to rapid population declines, habitat destruction, hunting, and climate change. India, as a biodiversity-rich nation, is home to several bird species under this category. Their protection is vital not just for ecological balance but also for meeting India’s global conservation commitments under the Convention on Biological Diversity (CBD) and Sustainable Development Goals (SDGs).
Birds listed under the Endangered (EN) category of the IUCN Red List face a very high risk of extinction in the near future. These species have experienced significant population declines or exist in fragmented and rapidly shrinking habitats. Conservation of these species is crucial for maintaining ecological balance, wetland health, and the integrity of riverine and forest ecosystems. Here’s a closer look at some prominent endangered birds found in India:
The Black-bellied Tern is a graceful riverine bird, notable for its slender body, black belly, and forked tail.
A critically rare and elusive bird, once believed to be extinct until its rediscovery in 1997.
Also known as the Indian Scissors-bill, it is one of the three skimmer species globally and the only one found in South Asia.
A large raptor with a strong preference for aquatic habitats, this eagle is often mistaken for other sea eagles.
Also known as Nordmann’s Greenshank, it is a migratory shorebird from the sandpiper family.
Distribution: Breeds in eastern Russia and migrates across East, South, and Southeast Asia during winter. In India, it is mainly recorded along the West Bengal and Odisha coasts.
A majestic bird of prey known for its well-feathered legs, hence the nickname “Booted Eagle.”
Distribution: Widespread across Central Asia, migrating to South Asia, Arabian Peninsula, and Africa during winter. In India, seen in open dry habitats, especially in Gujarat, Rajasthan, and Haryana.
Habitat: Prefers open steppes, semi-deserts, and mountainous areas; often perches on electricity poles.
Threats: Collision with power infrastructure, loss of open habitats, and poisoning from carcasses.
Conservation Status:
IUCN: Endangered
CITES: Appendix II
CMS: Appendix I
Conservation Efforts: Includes powerline insulation projects and monitoring migratory routes.
Birds under the Vulnerable (VU) category of the IUCN Red List face a high risk of extinction in the medium-term future if current trends continue. Many of these birds have undergone moderate population declines due to habitat loss, hunting, pollution, or climate change. Here’s a detailed overview of notable VU bird species in India:
A medium-sized diving duck, the Common Pochard is frequently observed in winter months across northern India.
One of the most iconic forest birds, the Great Indian Hornbill is known for its massive yellow casque and unique nesting behavior.
A large migratory eagle, often seen wintering in India. It is sometimes confused with the Steppe Eagle.
A large stork species, more solitary compared to the closely related Greater Adjutant.
A rare, island-endemic hornbill, found only on the volcanic Narcondam Island in the Andaman & Nicobar Islands.
A slender, fork-tailed water bird found in freshwater habitats across Asia.
The tallest flying bird in the world, often seen in pairs with a deep red neck and head.
Also known as the Swamp Partridge, this bird is ground-dwelling and secretive.
A rare songbird found only in certain parts of peninsular India.
Endemism: Restricted to the rocky hills and scrublands of the Deccan Plateau.
Birds listed under the Near Threatened (NT) category by the IUCN Red List are not currently endangered but are likely to qualify for a threatened category in the near future if the factors causing decline are not addressed. This list includes species that are essential indicators of environmental change and conservation priorities.
The Black-necked Crane is a revered species in Himalayan culture and plays a crucial ecological and cultural role.
Also called Hume’s Bar-tailed Pheasant, this bird is a terrestrial beauty and cultural emblem.
