What is the IUCN Red List?

The IUCN Red List is "designed to determine the relative risk of extinction, and the main purpose of the IUCN Red List is to catalogue and highlight those plants and animals that are facing a higher risk of global extinction (i.e. those listed as Critically Endangered, Endangered and Vulnerable). The IUCN Red List also includes information on plants and animals that are categorized as Extinct or Extinct in the Wild; on taxa that cannot be evaluated because of insufficient information (i.e., are Data Deficient); and on plants and animals that are either close to meeting the threatened thresholds or that would be threatened were it not for an ongoing taxon-specific conservation programme (i.e., are Near Threatened)."

Flagship Species

Flagship species are the symbolic pin-up species that lead environmental conservation efforts.

Some species are what WWF terms a priority species. A priority species means that it is one of the most ecologically, economically and/or culturally important species on our planet. And so WWF is working to ensure such species can live and thrive in their natural habitats.
