What are the different categories used by the IUCN Red List to classify species conservation status?
Extinct, Extinct in the Wild, Critically Endangered, Endangered, Vulnerable, Near Threatened, Least Concern, Data Deficient
What does the ‘Least Concern’ category mean on the IUCN Red List?
Species that are widespread and abundant
What does the ‘Critically Endangered’ category mean on the IUCN Red List?
Species facing an extremely high risk of extinction
What does the ‘Data Deficient’ category mean on the IUCN Red List?
Species for which there is insufficient information to determine their conservation status
What is the purpose of the IUCN Red List?
To provide information on the conservation status of species
Which organization maintains and updates the IUCN Red List?
International Union for Conservation of Nature (IUCN)
What is the main criteria used to assess a species’ conservation status on the IUCN Red List?
Population size, rate of decline, geographic range, and degree of population and distribution fragmentation
What is the Red List Index used for?
To track trends in the overall conservation status of groups of species over time
Which category on the IUCN Red List indicates a species is facing a high risk of extinction in the wild?
Critically Endangered
What does the ‘Near Threatened’ category mean on the IUCN Red List?
Species that are close to qualifying for a threatened category
What does the ‘Endangered’ category mean on the IUCN Red List?
Species facing a very high risk of extinction
What does the ‘Vulnerable’ category mean on the IUCN Red List?
Species facing a high risk of extinction
What does the ‘Extinct’ category mean on the IUCN Red List?
Species that are no longer in existence
What does the ‘Extinct in the Wild’ category mean on the IUCN Red List?
Species that exist only in captivity or as a naturalized population outside their historic range
Which category on the IUCN Red List indicates a species is not currently threatened with extinction?
Least Concern
What does the abbreviation IUCN Red List stand for?
International Union for Conservation of Nature Red List
How are species assessed for their conservation status on the IUCN Red List?
Using a set of criteria based on population size, rate of decline, geographic range, and fragmentation
What category on the IUCN Red List indicates a species’ conservation status is uncertain due to lack of data?
Data Deficient
What is the ultimate goal of the IUCN Red List?
To prevent species from becoming extinct
What is the significance of the IUCN Red List for conservation efforts?
It helps prioritize conservation actions and resources for species at greatest risk
What does the ‘Population size’ criterion on the IUCN Red List assess?
The number of individuals in a species population
What is the main purpose of the IUCN Red List Index?
To provide a measure of trends in the overall conservation status of groups of species
What does the ‘Rate of decline’ criterion on the IUCN Red List assess?
The speed at which a species population is decreasing
