The Minister included this species in the critically endangered category, effective from 19 August 2010 

Advice to the Minister for Environment Protection, Heritage and the Arts  

from the Threatened Species Scientific Committee (the Committee) 

on Amendment to the list of Threatened Species 

under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) 

 

1.



 

Reason for Conservation Assessment by the Committee 

This advice follows assessment of new information provided through the Species Information 

Partnership with Western Australia on: 

Verticordia apecta (Hay River Featherflower) 

 

2.



 

Summary of Species Details 

Taxonomy 

Conventionally accepted as Verticordia apecta (George and 

George, 1994). 

State Listing Status 

Listed as declared rare flora under the Western Australian 



Wildlife Conservation Act 1950. Managed as critically 

endangered by the Western Australian Government. 



Description 

A slender, erect shrub that can grow to 0.45 m high. The flowers 

are white or pink and the flowering period is in November 

(George and George, 1994; Western Australian Herbarium, 

2006). 

Distribution 

 

Endemic to Western Australia and known from a single 

population in the Mt Barker area, approximately 400 km south-

east of Perth. The species occurs on Crown Land in State Forest, 

which is proposed National Park (DEC, 2009).  

Relevant 

Biology/Ecology 

Grows in sandy clay with loam and broken granite, on an upper 

west-facing slope in Eucalyptus wandoo (Wandoo) low open 

woodland and low open shrubland (George and George, 1994). 

The species’ generation length is unknown (DEC, 2009).  

Threats 

 

Past 

Land clearing (DEC, 2009). 

Present 

Inappropriate fire regimes may affect the long-term viability of 

the species. Fire that is too frequent would most likely destroy 

soil-stored seed reserves and reduce vigour if fire occurs before 

regenerating or juvenile plants reach maturity, produce seed and 

replenish the soil seed bank (DEC, 2009). 

Dieback caused by Phytophthora cinnamomi is considered a 

threat to the species and is currently suspected to occur at the 

location of the only known population (DEC, 2009).

Public Consultation 

The information used in this assessment was made available for public exhibition and 

comment for 30 business days. No comments were received.

How judged by the Committee in relation to the EPBC Act criteria and Regulations 

 

Criterion 1: Not eligible 

It has undergone, is suspected to have undergone or is likely to undergo in the immediate 

future a very severe, severe or substantial reduction in numbers 

Criterion element 

Evidence 

Reduction in numbers 

No data. 

 

Criterion 2: Eligible for listing as critically endangered 

Its geographic distribution is precarious for the survival of the species and is very restricted, 

restricted or limited 



Criterion element 

Evidence 

Geographic distribution  

 

Very restricted – extent of occurrence is 100 m



2

 and area of 

occupancy is approximately 8 m

2

 (DEC, 2009). 



Geographic distribution 

precarious 

Yes – exists at a single location and continued decline is 

inferred due to ongoing threats (DEC, 2009). 

 

Criterion 3: Eligible for listing as critically endangered 

The estimated total number of mature individuals is very low, low or limited; and either 

(a) evidence suggests that the number will continue to decline at a very high, high or 

substantial rate; or 

(b) the number is likely to continue to decline and its geographic distribution is precarious for 

its survival 



Criterion element 

Evidence 

Total no. of mature 

individuals  

AND 


Very low – 16 mature plants (DEC, 2009). 

 

Continued rate of decline  



No data.

Criterion 4: Eligible for listing as critically endangered 

The estimated total number of mature individuals is extremely low, very low or low 

Criterion element 

Evidence 

Total no. of mature 

individuals  

Extremely low – 16 mature plants (DEC, 2009). 

 

Criterion 5: Not eligible 

Probability of extinction in the wild that is at least 

(a) 50% in the immediate future; or 

(b) 20% in the near future; or 

(c) 10% in the medium-term future 

 

Criterion element 

Evidence 

Probability of extinction 

in the wild  

No data. 



 

5.

 

Recovery Plan 

The Committee considers that there should not be a recovery plan for the Hay River 

Featherflower as the approved conservation advice for the species provides sufficient 

direction to implement priority actions and mitigate against key threats. 

 

6.

 

Recommendations 

(i) 

The Committee recommends that the list referred to in section 178 of the EPBC Act be 

amended by including in the list in the critically endangered category: 



Verticordia apecta 

(ii)  The Committee recommends that there should not be a recovery plan for this species.
