Biodiversity Conservation: IUCN Red List Categories, Hotspots, In Situ vs Ex Situ and the Treaty Years

Why Conservation Questions Repeat

Biodiversity is the variety of life at three levels: genes, species and ecosystems. Exams love conservation because it is full of lists with exact numbers, and a list is easy to test with a single wrong option.

The core machinery is small. The IUCN, the International Union for Conservation of Nature, founded in 1948 and based in Gland, Switzerland, grades species on its Red List. The Red Data Book keeps the record, with red pages for threatened species and green pages for ones that have recovered.

Beyond grading, conservation has two routes: in situ, which protects species in their natural habitat, and ex situ, which protects them outside it. Then come the treaties, each tied to one job and one year. Learn the job with the year and the distractors lose their power.

1. Which IUCN Red List category is used when a species survives only in captivity or cultivation?

2. A region qualifies as a biodiversity hotspot if it has at least 1,500 endemic vascular plant species and has lost at least what share of its original habitat?

3. How many of the world's biodiversity hotspots are found in India?

4. Which of the following is an example of ex situ conservation?

5. In the Red Data Book, the pages that list species which have recovered from the threatened status are:

6. Which international agreement, signed in 1973, regulates trade in endangered species of wild fauna and flora?

7. Which IUCN category lies between Vulnerable and Critically Endangered?

8. Which animal was declared extinct in India in 1952?
