Answer:

The IUCN Red List of Threatened Species™ is the world's most comprehensive inventory of the global

conservation status of plant and animal species.

It uses a set of quantitative criteria to evaluate the

extinction risk of thousands of species. These criteria

are relevant to most species and all regions of the world.

With its strong scientific base, the IUCN Red List is recognised as the

most authoritative guide to the status of biological diversity.
