Where is the headquarters of the International Union for Conservation of Nature (IUCN)?
Correct Answer: B. Gland, Switzerland
The IUCN is headquartered in Gland, Switzerland, a small town near Geneva. It was founded in 1948 as the world's first global environmental organization. IUCN is the largest professional global conservation network with over 16,000 expert volunteers in more than 160 countries.
In which year was the IUCN (International Union for Conservation of Nature) founded?
Correct Answer: B. 1948
Wait — the correct answer here is 1948. IUCN was founded on October 5, 1948, at a conference in Fontainebleau, France. It was initially called the International Union for the Protection of Nature (IUPN) and later renamed IUCN in 1956. It works to conserve nature and ensure equitable use of natural resources.
In which year was the IUCN founded?
Correct Answer: B. 1948
The IUCN was founded on October 5, 1948, at a conference in Fontainebleau, France. It was initially named the International Union for the Protection of Nature (IUPN) and was renamed IUCN in 1956. It is the world's largest and most diverse environmental network, working to conserve biodiversity globally.
How many categories are there in the IUCN Red List of Threatened Species?
Correct Answer: C. 9
The IUCN Red List has 9 categories: Extinct (EX), Extinct in the Wild (EW), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD), and Not Evaluated (NE). These categories provide a framework for assessing the relative risk of extinction of any species globally. The Red List is the world's most comprehensive inventory of the conservation status of biological species.
Which IUCN Red List category applies to a species that no longer exists anywhere on Earth?
Correct Answer: C. Extinct (EX)
The 'Extinct (EX)' category is assigned to a taxon when there is no reasonable doubt that the last individual has died. A taxon is presumed extinct when exhaustive surveys have been unable to record an individual. The Dodo and Passenger Pigeon are well-known examples of species classified as Extinct.
What does the IUCN category 'Extinct in the Wild (EW)' mean?
Correct Answer: B. The species survives only in captivity or cultivation
Extinct in the Wild (EW) means the species is known only to survive in captivity, in cultivation, or as a naturalized population well outside its past range. Exhaustive surveys throughout the known and/or expected habitat have failed to detect any individuals. The Arabian Oryx was once classified as EW before being successfully reintroduced into the wild.
Which IUCN Red List category indicates a species facing an extremely high risk of extinction in the wild?
Correct Answer: D. Critically Endangered (CR)
Critically Endangered (CR) is the IUCN category assigned to species facing an extremely high risk of extinction in the wild. It is the highest risk category for wild species, just below Extinct in the Wild and Extinct. Species are classified as CR if their population has declined by 80% or more over the last 10 years or three generations.
What is the IUCN Red List category for a species facing a high risk of extinction in the wild?
Correct Answer: C. Endangered (EN)
Endangered (EN) refers to a species that faces a high risk of extinction in the wild. A species is listed as EN if its population has declined by 50-70% over 10 years or three generations, or its extent of occurrence is less than 5,000 sq km. Tigers, Asiatic Lions, and Asian Elephants are examples of EN species.
Under the IUCN classification, a species at high risk of extinction but not yet 'Endangered' is listed as:
Correct Answer: D. Vulnerable
Vulnerable (VU) is the IUCN category for species at high risk of extinction in the wild if the circumstances threatening their survival continue. The population decline threshold for VU is 30-50% over 10 years or three generations. The Gaur (Indian Bison) and Sloth Bear are examples of Vulnerable species in India.
What does the IUCN category 'Near Threatened (NT)' indicate?
Correct Answer: B. The species is close to qualifying as Vulnerable
Near Threatened (NT) indicates that a species is close to qualifying for, or is likely to qualify for, a threatened category in the near future. It does not meet the criteria for Critically Endangered, Endangered, or Vulnerable, but is under watch. The Striped Hyena and Indian Grey Wolf are examples of NT species.
