Federal and state conservation status codes are distinguished by the use of upper case or lower case letters

ROTAP Codes
The following categories are used in the Schedules to the Endangered Species Protection Act and in the ANZECC lists of threatened flora:
Endangered
- A species is Endangered if:
- it is likely to become Extinct unless the circumstances and factors threatening its abundance, survival or evolutionary development cease to operate; or
- its numbers have been reduced to such a critical level, or its habitats have been so drastically reduced, that it is in immediate danger of Extinction; or
- it might already be Extinct, but is not presumed Extinct.
- A species is Vulnerable at a particular time if:
- within the next 25 years, the species is likely to become Endangered unless the circumstances and factors threatening its abundance, survival or evolutionary development cease to operate.
- A species is presumed Extinct at a particular time if:
- it has not been definitely located in nature during the preceding 50 years; or
- it has not been definitely located in nature during the preceding 10 years despite thorough searching during the period.
ROTAP Codes
- The 'ROTAP Codes' are those given in Briggs & Leigh (1996) Rare or Threatened Australian Plants.
- There are an aggregate code giving the Distribution Category (1, 2 or 3), the Conservation Status (X, E, V, R, or K, with or without C) and and indication of the Size Class or Reserved Populations (a, i, t, -, or +):
- 1 Known from one collection only
- 2 Geographic range in Australia less than 100 km
- 3 Geographic range in Australia greater than 100 km.
- X Presumed extinct. Comparable to ANZECC and ESP categories.
- E Endangered. Comparable to ANZECC and ESP categories.
- V Vulnerable. Comparable to ANZECC and ESP categories.
- R Rare.
- K Poorly known.
- C Reserved. At least one population in National Park or other proclaimed reserve(s).
- a 1000 plants or more are known to occur within a conservation reserve(s).
- i Less than 1000 plants are know to occur within a conservation reserve(s). - Reserved population size is not adequately known.
- t Total known population is reserved.
- + Taxon has a natural occurrence overseas.
