NZCTS database Find reports and assessment data from the current and historic New Zealand Threat Classification System (NZTCS) database.

Naturally Uncommon: naturally small population and therefore susceptible to harmful influences.

Relict: small population stabilised after declining.

Recovering: population increasing after previously declining.Declining: population declining but still moderately common.Nationally Increasing: small but increasing population still facing a risk of extinction in the medium term.Īt Risk species aren’t considered Threatened, but they could quickly become so if conservation management reduces, if a new threat arises, or declines continue unabated.Nationally Vulnerable: facing high risk of extinction in the medium term.Nationally Endangered: facing high risk of extinction in the short term.Nationally Critical: most severely threatened, facing an immediate high risk of extinction.Threatened species have the greatest risk of extinction. An endangered species is one specific risk category.A threatened species is an umbrella term used to describe a range of risk categories.In the New Zealand Threat Classification System these terms mean two different things.

Is the population state a result of human-induced effects?ĭifference between endangered and threatenedĮndangered species and threatened species are to many people just different ways of describing the same thing-an at-risk plant or animal.

If the population is stable, has it declined in the past?.How much is the population estimated to rise or fall over either the next three generations or 10 years (whichever is longer)?.What’s the current population size? This can be the number of breeding adults or the area of occupied habitat.Panels of experts from New Zealand’s scientific community determine a species' conservation status using the following assessments:
