Explanation of Conservation Codes 

 

Table C.1: Definition of categories described under the EPBC Act. 

Conservation Category 

Definition 

Extinct 


A species is extinct if there is no reasonable doubt that the last member 

of the species has died. 

Extinct in the wild 

A  species  is  categorised  as extinct in the wild if it is only known to 

survive in cultivation, in captivity or as a naturalised population well 

outside its past range; or if it has not been recorded in its 

known/expected habitat, at appropriate seasons, anywhere in its past 

range, despite exhaustive surveys over a time frame appropriate to its 

life cycle and form. 

Critically Endangered 

The species is facing an extremely high risk of extinction in the wild in 

the immediate future. 

Endangered 

The species 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. 

Vulnerable 

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. 

Conservation Dependent 

The species is the focus of a specific conservation programme, the 

cessation of which would result in the species becoming vulnerable, 

endangered or critically endangered within a period of five years. 

 

Table C.2: Definition of Declared Rare and Priority categories.

 

Code 



Definition 

DRF 


 

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.  

P1:  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. 

P2:  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. 


P3:  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. 

P4:  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.

Table C.3: Explanation of codes for Threatened Ecological Communities (TEC) and Priority 

Ecological Communities (PEC) 

 

Code 

Definition 

TECs 

PD:  Presumed Totally 

Destroyed 

An ecological community that 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 

CR:  Critically 

Endangered 

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. 

EN:  Endangered 

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. 

VU:  Vulnerable 

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. 



PECs 

P1:  Priority One 

Ecological communities with apparently few, small occurrences, all or most 

not actively managed for conservation (e.g. within agricultural or pastoral 

lands, urban areas, active mineral leases) and for which current threats 

exist.  Communities may be included if they are comparatively well-known 

from one or more localities but do not meet adequacy of survey 

requirements, and/or are not well defined, and appear to be under 

immediate threat from known threatening processes across their range. 

P2:  Priority Two 

Communities  that  are  known  from few small occurrences, all or most of 

which are actively managed for conservation (e.g. within national parks, 

conservation parks, nature reserves, State forest, unallocated Crown land, 

water reserves, etc.) and not under imminent threat of destruction or 

degradation.  Communities may be included if they are comparatively well 

known from one or more localities but do not meet adequacy of survey 

requirements, and/or are not well defined, and appear to be under threat 

from known threatening processes. 

P3:  Priority Three 

(i)  Communities  that  are  known from several to many occurrences, a 

significant number or area of which are not under threat of habitat 

destruction or degradation or: 

(ii) Communities known from a few widespread occurrences, which are

Definition 

either large or within significant remaining areas of habitat in which other 

occurrences may occur, much of it not under imminent threat, or; 

(iii) Communities made up of large, and/or widespread occurrences, that 

may or not be represented in the reserve system, but are under threat of 

modification across much of their range from processes such as grazing by 

domestic and/or feral stock, and inappropriate fire regimes.  

Communities may be included if they are comparatively well known from 

several localities but do not meet adequacy of survey requirements and/or 

are not well defined, and known threatening processes exist that could affect 

them. 

P4:  Priority Four 



Ecological communities that are adequately known, Rare but not threatened 

or meet criteria for Near Threatened, or that have been recently removed 

from the threatened list.  These communities require regular monitoring.   

(a)  Rare.  Ecological communities known from few occurrences that are 

considered to have been adequately surveyed, or for which sufficient 

knowledge is available, and that are considered not currently threatened or 

in need of special protection, but could be if present circumstances change.  

These communities are usually represented on conservation lands. 

(b)  Near Threatened.  Ecological communities that are considered to have 

been adequately surveyed and that do not qualify for Conservation 



Dependent, but that are close to qualifying for Vulnerable

(c) Ecological communities that have been removed from the list of 

threatened communities during the past five years.   

P5:  Priority Five  

Ecological communities that are not threatened but are subject to a specific 

conservation programme, the cessation of which would result in the 

community becoming threatened within five years. 

 

 



Table C.4: Explanation of codes for Declared Weeds in Western Australia. 

Priority 

Requirements 

P1 

 

Prohibits movement 



The movement of plants or their seeds is prohibited within the 

State.  This prohibits the movement of contaminated machinery 

and produce, including livestock and fodder. 

P2 

 

Aim is to eradicate 



infestation 

Treat all plants to destroy and prevent propagation each year until 

no plants remain.  The infested area must be managed in such a 

way that prevents the spread of seed or plant parts on or in 

livestock, fodder, grain, vehicles and/or machinery.

Priority 

Requirements 

P3 

 

Aims to control infestation by 



reducing area and/or density 

of infestation 

 

The infested area must be managed in such a way that prevents 



the spread of seed or plant parts within and from the property, on 

or in livestock, fodder, grain, vehicles and/or machinery. 

Treat to destroy and prevent seed set for all plants: 

  within 100 metres inside of the boundaries of the 



infestation.  

  within 50 metres of roads and high-water marks on 



waterways.  

 



within 50 metres of sheds, stock yards and houses.  

Treatment must be done prior to seed set each year. 

Of the remaining infested area: 

  Where plant density is 1-10 per hectare, treat 100% of 



infestation.  

  Where plant density is 11-100 per hectare, treat 50% of 



infestation.  

 



Where plant density is 101-1000 per hectare, treat 10% of 

infestation.  

Properties with less than two hectares of infestation must treat the 

entire infestation. 

Additional areas may be ordered to be treated.  

P4 

 

Aims to prevent infestation 



spreading beyond existing 

boundaries of infestation 

The infested area must be managed in such a way that prevents 

the spread of seed or plant parts within and from the property, on 

or in livestock, fodder, grain, vehicles and/or machinery. 

Treat to destroy and prevent seed set for all plants: 

 

within 100 metres inside of the boundaries of the infested 



property.  

  within 50 metres of roads and high-water marks on 



waterways.  

 



within 50 metres of sheds, stock yards and houses.  

  Treatment must be done prior to seed set each year.  



Properties with less than two hectares of infestation must 

treat the entire infestation. 

Additional areas may be ordered to be treated.  

Special considerations:  

In the case of P4 infestations where they continue across property 

boundaries, there is no requirement to treat the relevant part of the 

property boundaries as long as the boundaries of the infestation 

as a whole are treated.  There must be agreement between 

neighbours in relation to the treatment of these areas.  

P5 

 

Infestations on public lands must be controlled.
