Lower risk categories
2001 Categories & Criteria (version 3.1)	Description	1994 Categories & Criteria (version 2.3)
	Least Concern (LC or LR/lc), lowest risk. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
	Near Threatened (NT or LR/nt), is close to qualifying for or is likely to qualify for a threatened category in the near future.
No longer a Red List category	Conservation Dependent (LR/cd), the focus of a continuing taxon-specific or habitat-specific conservation programme targeted towards the taxon in question, the cessation of which would result in the taxon qualifying for one of the threatened categories below within a period of five years.

Threatened categories

	Data Deficient (DD), inadequate information to make a direct, or indirect, assessment of its risk of extinction.
	Not Evaluated (NE), not yet been evaluated against the criteria.
	Possibly Extinct (PE), a category given by BirdLife International. A subcategory of CR.
