This is a measure of the number of species that showed genuine changes in their conservation status between the two New Zealand Threat Classification System (NZTCS) listing cycles of 2005 and 2008–11.
Purpose of collection
The number of indigenous animal and plant species with a change in conservation status is reported as an impact of changes in the state of our freshwater, land, and marine environments. A change in a species’ conservation status reflects a change in its risk of extinction.
Method of collection/Data provider
The New Zealand Threat Classification System helps quantify the risk of all indigenous plants, animals, and fungi becoming extinct. The Department of Conservation developed the NZTCS to provide a national system similar to the International Union for Conservation of Nature and Natural Resources (IUCN) Red List. The NZTCS is used to monitor the status of individual species and report on the state of indigenous biodiversity.
