Which IUCN category is assigned to species that are widespread and abundant?
Correct Answer: D. Least Concern (LC)
Least Concern (LC) is assigned to taxa that have been evaluated and do not qualify for Critically Endangered, Endangered, Vulnerable, or Near Threatened categories. Least Concern taxa are widespread and abundant. The Common Leopard and Jungle Cat are examples of species classified as Least Concern.
The IUCN category 'Data Deficient (DD)' means:
Correct Answer: C. Inadequate information to assess extinction risk
Data Deficient (DD) is assigned when there is inadequate information to make a direct or indirect assessment of the risk of extinction based on the species' distribution and/or population status. A DD species may or may not be threatened. It is not a threatened category but indicates a need for more research.
Which IUCN category applies to a species that has not yet been evaluated against the Red List criteria?
Correct Answer: C. Not Evaluated (NE)
Not Evaluated (NE) is assigned to a taxon that has not yet been assessed against the Red List criteria. This may be because the species was only recently discovered, is very difficult to study, or has simply not been assessed yet. It does not imply any particular level of conservation concern.
The Gharial (Gavialis gangeticus) is listed under which IUCN Red List category?
Correct Answer: D. Critically Endangered (CR)
The Gharial is listed as Critically Endangered (CR) on the IUCN Red List due to severe population decline caused by habitat loss, sand mining, and depletion of fish stocks. Its population dropped by over 98% in the 20th century. It is found in a few river systems in India and Nepal, including the Chambal, Girwa, and Gandak rivers.
The Hangul (Kashmir Stag) is listed under which IUCN Red List category?
Correct Answer: B. Critically Endangered (CR)
The Hangul or Kashmir Stag (Cervus hanglu hanglu) is listed as Critically Endangered on the IUCN Red List, with fewer than 200 individuals remaining. It is found only in the Dachigam National Park in Jammu and Kashmir. Poaching, habitat destruction, and military activities have drastically reduced its population.
The Great Indian Bustard (Ardeotis nigriceps) is classified under which IUCN category?
Correct Answer: C. Critically Endangered (CR)
The Great Indian Bustard is classified as Critically Endangered on the IUCN Red List, with fewer than 150 individuals remaining in the wild. It faces threats from habitat loss due to agricultural expansion, power line collisions, and hunting. Project Great Indian Bustard has been launched by India to conserve this species primarily found in Rajasthan and Gujarat.
The Malabar Large-spotted Civet is listed under which IUCN Red List category?
Correct Answer: D. Critically Endangered (CR)
The Malabar Large-spotted Civet (Viverra civettina) is listed as Critically Endangered on the IUCN Red List due to its extremely restricted range in the Western Ghats of Kerala and Karnataka. It is one of the world's most endangered carnivores. Habitat destruction, hunting, and pesticide use have drastically reduced its population to fewer than 250 mature individuals.
The Bengal Tiger (Panthera tigris tigris) is listed under which IUCN Red List category?
Correct Answer: C. Endangered (EN)
The Bengal Tiger is classified as Endangered (EN) on the IUCN Red List, though its population has been increasing due to conservation efforts in India. India's tiger census 2022 recorded over 3,167 tigers, the world's largest tiger population. The species faces threats from poaching, habitat fragmentation, and human-wildlife conflict.
The Asiatic Lion (Panthera leo persica) is listed under which IUCN Red List category?
Correct Answer: B. Endangered (EN)
The Asiatic Lion is classified as Endangered (EN) on the IUCN Red List. Its wild population is entirely restricted to the Gir Forest National Park in Gujarat, India, making it one of the most geographically restricted big cats in the world. The population has grown from 177 in 1968 to over 674 in the 2020 census.
The Asian Elephant (Elephas maximus) is classified under which IUCN Red List category?
Correct Answer: D. Endangered (EN)
The Asian Elephant is classified as Endangered (EN) on the IUCN Red List, with the population declining due to habitat loss, fragmentation, and human-elephant conflict. India holds the largest population of wild Asian Elephants, with over 27,000 individuals. Project Elephant was launched in India in 1992 to protect elephant habitats and corridors.
