R: 



Declared Rare Flora – Extant Taxa 

 

 



Taxa which have been adequately searched for and are deemed to be in the 

wild either rare, in danger of extinction, or otherwise in need of special 

protection, and have been gazetted as such. 

 

X: 



Declared Rare Flor a – Presumed Extinct Taxa 

 

 



Taxa which have not been collected, or otherwise verified, over the past 50 

years despite thorough searching, or of which all known wild populations have 

been destroyed more recently, and have been gazetted as such. 

 

1: 



Priority One – Poorly Known Taxa 

 

 



Taxa which are known from one or a few (generally <5) populations which are 

under threat, either due to small population size, or being on lands under 

immediate threat, e.g. road verges, urban areas, farmland, active mineral 

leases, etc., or the plants are under threat, e.g. from disease, grazing by feral 

animals, etc.  May include taxa with threatened populations on protected 

lands.  Such taxa are under consideration for declaration as ‘rare flora’, but are 

in urgent need of further survey. 

 

2: 



Priority Two – Poorly Known Taxa 

 

 



Taxa which are known from one or a few (generally <5) populations, at least 

some of which are not believed to be under immediate threat (i.e. not currently 

endangered).  Such taxa are under consideration for declaration as ‘rare flora’, 

but are in urgent need of further survey. 

 

3: 


Priority Three – Poorly Known Taxa 

 

 



Taxa which are known from several populations, and the taxa are not believed 

to be under immediate threat (i.e. not currently endangered), either due to the 

number of known populations (generally >5), or known populations being 

large, and either widespread or protected.  Such taxa are under consideration 

for declaration as ‘rare flora’ but are in need of further survey. 

 

4: 



Priority Four – Rare Taxa 

 

 



Taxa which are considered to have been adequately surveyed and which, 

whilst being rare (in Australia), are not currently threatened by any 

identifiable factors.  These taxa require monitoring every 5-10 years.

Appendix A: 



Definitions of Threatened Ecological Communities 

(DEC 2009b) 

 

 



Presumed Totally Destroyed (PD) 

An ecological community which has been adequately searched for but for which no 

representative occurrences have been located. The community has been found to be 

totally destroyed or so extensively modified throughout its range that no occurrence 

of it is likely to recover its species composition and/or structure in the foreseeable 

future. 


 

An ecological community will be listed as presumed totally destroyed if there are no 

recent records of the community being extant and either of the following applies ( A 

or B): 


 

A) Records within the last 50 years have not been confirmed despite thorough 

searches of known or likely habitats or 

 

B) All occurrences recorded within the last 50 years have since been destroyed 



 

Critically Endangered (CR) 

An ecological community that has been adequately surveyed and found to have been 

subject to a major contraction in area and/or that was originally of limited distribution 

and is facing severe modification or destruction throughout its range in the immediate 

future, or is already severely degraded throughout its range but capable of being 

substantially restored or rehabilitated. 

 

An ecological community will be listed as Critically Endangered when it has been 



adequately surveyed and is found to be facing an extremely high risk of total 

destruction in the immediate future. This will be determined on the basis of the best 

available information, by it meeting any one or more of the following criteria (A, B 

or C): 


 

A) The estimated geographic range, and/or total area occupied, and/or number 

of discrete occurrences since European settlement have been reduced by at 

least 90% and either or both of the following apply (i or ii): 

 

i) geographic range, and/or total area occupied and/or number of discrete 



occurrences are continuing to decline such that total destruction of the 

community is imminent (within approximately 10 years); 

 

ii) modification throughout its range is continuing  such that in the 



immediate future (within approximately 10 years) the community is 

unlikely to be capable of being substantially rehabilitated. 

 

B) Current distribution is limited, and one or more of the following apply (i, 



ii or iii): 

 

i) geographic range and/or number of discrete occurrences, and/or area 



occupied is highly restricted and the community is currently subject to

known threatening processes which are likely to result in total destruction 



throughout its range in the immediate future (within approximately 10 

years); 


 

ii) there are very few occurrences, each of which is small and/or isolated 

and extremely vulnerable to known threatening processes; 

 

iii) there may be many occurrences but total area is very small and each 



occurrence is small and/or isolated and extremely vulnerable to known 

threatening processes. 

 

C) The ecological community exists only as highly modified occurrences that 



may be capable of being rehabilitated if such work begins in the immediate 

future (within approximately 10 years). 

 

 

Endangered (EN) 



An ecological community that has been adequately surveyed and found to have been 

subject to a major contraction in area and/or was originally of limited distribution and 

is in danger of significant modification throughout its range or severe modification or 

destruction over most of its range in the near future. 

 

An ecological community will be listed as Endangered when it has been adequately 



surveyed and is not Critically Endangered but is facing a very high risk of total 

destruction in the near future. This will be determined on the basis of the best 

available information by it meeting any one or more of the following criteria (A, B, 

or C): 


 

A) The geographic range, and/or total area occupied, and/or number of 

discrete occurrences have been reduced by at least 70% since European 

settlement and either or both of the following apply (i or ii): 

 

i) the estimated geographic range, and/or total area occupied and/or 



number of discrete occurrences are continuing to decline such that total 

destruction of the community is likely in the short term future (within 

approximately 20 years); 

 

ii) modification throughout its range is continuing such that in the short 



term future (within approximately 20 years) the community is unlikely to 

be capable of being substantially restored or rehabilitated. 

 

B) Current distribution is limited, and one or more of the following apply (i, 



ii or iii): 

 

i) geographic range and/or number of discrete occurrences, and/or area 



occupied is highly restricted and the community is currently subject to 

known threatening processes which are likely to result in total destruction 

throughout its range in the short term future (within approximately 20 

years);

ii) there are few occurrences, each of which is small and/or isolated and 



all or most occurrences are very vulnerable to known threatening 

processes; 

 

iii) there may be many occurrences but total area is small and all or most 



occurrences are small and/or isolated and very vulnerable to known 

threatening processes. 

 

C) The ecological community exists only as very modified occurrences that 



may be capable of being substantially restored or rehabilitated if such work 

begins in the short-term future (within approximately 20 years). 

 

 

 



Vulnerable (VU) 

An ecological community that has been adequately surveyed and is found to be 

declining and/or has declined in distribution and/or condition and whose ultimate 

security has not yet been assured and/or a community that is still widespread but is 

believed likely to move into a category of higher threat in the near future if 

threatening processes continue or begin operating throughout its range. 



 

An ecological community will be listed as Vulnerable  when it has been adequately 

surveyed and is not Critically Endangered or Endangered but is facing a high risk of 

total destruction or significant modification in the medium to long term future. This 

will be determined on the basis of the best available information by it meeting any 

one or more of the following criteria (A, B or C): 

 

A) The ecological community exists largely as modified occurrences that are 



likely to be capable of being substantially restored or rehabilitated. 

 

B) The ecological community may already be modified and would be 



vulnerable to threatening processes, is restricted in area and/or range and/or is 

only found at a few locations. 

 

C) The ecological community may be still widespread but is believed likely to 



move into a category of higher threat in the medium to long term future 

because of existing or impending threatening processes.
