Which color sheet in Red Data Book represents extinct species?

Historic Red Data Book introduced by IUCN used color-coded loose-leaf pages for quick visual signaling of conservation status to policymakers before digital databases. Red sheets indicated endangered, amber vulnerable, white rare, green out of danger recovering, grey insufficiently known, and black sheets denoted species confirmed extinct or possibly extinct. Black symbolized irreversible loss and mourning. Although modern Red List is electronic, textbook references retain black sheet representing extinct because color concept remains memorable mnemonic for school examinations. Knowledge of this distribution aids in understanding endemism patterns and UNESCO heritage site designations across India.

Which book lists species according to their extinction risk?

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.
