Question

Species listed in Red Data Book are
A. Vulnerable
B. Threatened
C. Endangered
D. All of the above

Answer 1

Hint: The red data book is a comprehensive document containing information about the various endangered and threatened species of flora and fauna present of each region. It includes information in a colour-coded format that denotes, extinct, endangered, threatened, vulnerable, and rare species. The main idea of the book is to protect and identify species on the brink of extinction.

Complete answer:
The book originated in Russia based on biodiversity research conducted in 1961 to 1964 by biologists in the northeastern region of Russia and was called the Red Data Book of the Russian Federation (RDBRF) or also the Russian Red Data Book. The most comprehensive and detailed information of all species is maintained by the IUCN (International Union for Conservation of Nature). The main ideology behind maintaining the book is to aid in research and help to protect and identify threatened species. The book broadly classifies species into threatened, not threatened, and unknown. In the case of threatened species, the book contains a colour coded system where each colour denotes a specific type of threatened species.
a) Black- extinct
b) Red- endangered
c) Amber-vulnerable
d) White- rare
e) Green- formerly endangered
f) Gray- not threatened
Therefore, the correct answer is option (D).

Note: The main advantage of having the red data book is that it gives an insight as to the conservation status and population status of various species, extremely helpful in taxonomic research, and helps lawmakers make better guidelines for the protection of endangered species. Unfortunately, the red data book is incomplete and un-updated and has no record of microbes.
