摘要

International Union for Conservation of Nature (IUCN, temporarily named World Conservation Union 1990-2008) Red List categories

**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 program 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**
2001 Categories & Criteria (version 3.1)	Description	1994 Categories & Criteria (version 2.3)
	Vulnerable (VU), considered to be facing a high risk of extinction in the wild
	Endangered (EN), considered to be facing a very high risk of extinction in the wild.
	Critically Endangered (CR), facing an extremely high risk of extinction in the wild.

**Other categories**
2001 Categories & Criteria (version 3.1)	Description	1994 Categories & Criteria (version 2.3)
	Extinct in the Wild (EW), known only to survive in cultivation, in captivity or as a naturalized population (or populations) well outside the past range.
	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.
	Possibly Extinct in the Wild (PEW), A term used within the IUCN Red List. A subcategory of CR.
Image:Status iucn3.1 PLC.svg	Possibly Least Concern (PLC), Used for a term within the IUCN Yellow List. A subcategory of NT.	Image:Status iucn2.3 PLC.svg
	Extinct (EX), there is no reasonable doubt that the last individual has died.

This file is translated using SVG <switch> elements. All translations are stored in the same file! Learn more.

For most Wikipedia projects, you can embed the file normally (without a lang parameter). The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:Status iucn3.1.svg|lang=en]] for the English version. Do not specify a lang parameter if it is not needed. The parameter may prevent the use of a subsequent translation.

To translate the text into your language, you can use the SVG Translate tool. Alternatively, you can download the file to your computer, add your translations using whatever software you're familiar with, and re-upload it with the same name. You will find help in Graphics Lab if you're not sure how to do this.
