摘要

Graphic diagram showing the 2008 New Zealand Threat Classification System categories, used by the New Zealand Department of Conservation. These categories replace the 2002 NZTCS.

At Risk categories

2002 Categories	Description	2008 Categories
	Range Restricted (RR): small population only found in a particular habitat or area.	Now a qualifier, not a NZTCS category
	Sparse (SP); rare and localised.	Now a qualifier, not a NZTCS category
	Gradual Decline (GD): a moderate to large population with a small to moderate rate of decline.	No longer a NZTCS category
	Serious Decline (SD): a moderate to large population with moderate to large predicted decline.	No longer a NZTCS category
—	Naturally Uncommon (NU): naturally occurring as small or widely-scattered populations.
—	Relict (REL): occupying less than 10% of their former range, but stable or increasing.
—	Recovering (R): previously declining, but now showing an ongoing or predicted increase.
—	Declining (D): buffered by a large population or a slow decline rate, but may become Threatened in the future.

Threatened categories

2002 Categories	Description	2008 Categories
	Nationally Vulnerable (VU): a small or localised population facing gradual decline.
	Nationally Endangered (NE): a small to moderate population declining at a moderate to high rate.
	Nationally Critical (NC): a very small (less than 250 individuals) or very localised population, or one rapidly declining, or both.

Other categories

2002 Categories	Description	2008 Categories
	Not Threatened (NT): an assessed native NZ species that does not qualify as At Risk or Threatened.
	Data Deficient (DD): insufficient information is available to make as assessment on conservation status.
	Extinct (EX): there is no reasonable doubt that no individuals exist. For these lists only species that have become extinct since 1840 are listed.
