Talk:New Zealand Threat Classification System

Template needed

A range of diagrams for the differing conservation status levels exists at commons:Category:NZTCS Category diagrams. A template using these should be made and added to all species listed in the New Zealand Threat Classification System lists. A BIG job! Any such template should not override the IUCN Red List conservation status template. -- Alan Liefting (talk) - 06:05, 3 May 2008 (UTC)

There is a template, @Alan Liefting:. It is in the taxobox/speciesbox template system: Wikipedia:Conservation status#New Zealand: NZTCS. However, it seems out of date. But then again, so is this article. Current evaluations are here. Nessie (talk) 16:07, 2 February 2018 (UTC)

There are now diagrams for both the original (2002) and revised (2008) TCS categories at commons:Category:NZTCS Category diagrams (Alan, I corrected the misprint in your link above). The template has also been updated but the categories DD and NT are not currently working. —Giantflightlessbirds (talk) 07:44, 4 September 2021 (UTC)

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.
