Practice question
Question
Which book lists species according to their extinction risk?
Explanation
Red Data Book was conceived by IUCN in 1964 under Sir Peter Scott, chairman of Survival Service Commission, to systematically document threatened species globally. It evaluates taxa against quantitative criteria for extinction risk, population trend, and distribution. Publication uses categories from Extinct to Least Concern, supported by detailed justification, maps, and threats analysis. Red Data Book provides scientific basis for national wildlife protection acts, CITES appendices, and conservation prioritization. Regional and national Red Data Books extend global assessments to local contexts. Such details are high-yield for NEET and CUET as they link morphological classification with modern molecular phylogeny insights.
