Red Data List of Threatened Iranian Fungi

IUCN categories in Iran

EXTINCT (EX)

A taxon is presumed extinct when surveys in known and/or expected habitat throughout its historic range have failed to record an individual. For this evaluation, a period of 50 years is generally used, providing there have been reasonable attempts to re-discover the species concerned.

NEAR THREATENED (NT)

A taxon is Near Threatened when it is has been evaluated against the criteria but does not qualify for Critically Endangered, Endangered or Vulnerable now, but is close to qualifying for or is likely to qualify for a threatened category in the near future.

LEAST CONCERN (LC)

A taxon is Least Concern when it has been evaluated against the criteria and does not qualify for Critically Endangered, Endangered, Vulnerable or Near Threatened. Widespread and abundant taxa are included in this category.

DATA DEFICIENT (DD)

A taxon is Data Deficient when there is inadequate information to make a direct, or indirect, assessment of its risk of extinction based on its distribution and/or population status. Whilst Data Deficient could be considered not to be a category of threat, in practice it must be a matter of grave concern that a threat status cannot be assigned. Some of these species could be critically endangered. Consequently a high priority should be attached to securing resources to further investigate these species.

NOT EVALUATED (NE)

A taxon is Not Evaluated when it has not yet been evaluated against the criteria. There can be many reasons for this. Often it is due to some taxonomic issue.
