Following on from Stephen Ambrose's Federal definitions, following are
extracts of descriptions of "Division 2 - Classes of Wildlife", as
defined on pages 50-52 of the Queensland Nature Conservation Act 1992:
Presumed Extinct, Endangered, Vulnerable, Rare or Common.
- if it has not been sighted in the wild for a period critical to its
life cycle despite thorough search.
- in danger of extinction;
- survival in the wild is unlikely if threatening processes continue.
Taken to be in danger of extinction if:
a) its number has been reduced to a critical level or its habitat has
been so drastically reduced that it may be in immediate danger of
b) it has not been sighted in the wild for a period critical to its life
cycle although no thorough search has been made for it.
- survival in the wild is vulnerable if threatening processes continue
a) its population is decreasing because of threatening processes; or
b) its population has been seriously depleted and its protection is not
c) its population, while abundant, is at risk because of threatening
d) its population is -
i) low or localised; or
ii) dependent on limited habitat that is at risk because of
- population is represented by:
a) a relatively large population in a restricted range; or
b) smaller populations thinly spread over a wider range
- common or abundant; and
- likely to survive in the wild.
I will check further on Monday, but at this stage it appears that, for
Queensland, the Beach Thick-knee is cited as "vulnerable" in the Nature
Conservation (Wildlife) Regulation 1994 SL No. 474, but the Bush
Thick-knee is not mentioned.
For the State of Queensland, as per the Regulation, a bush thick-knee
may be considered as common, as a "common" bird is "a bird indigenous to
Australia, other than a presumed extinct, endangered, vulnerable or rare
Where did you read the definition of "threatened" for the Bush
