Approved Conservation Advice  

(s266B of the Environment Protection and Biodiversity Conservation Act 1999

Approved Conservation Advice for 

Verticordia crebra  

This Conservation Advice has been developed based on the best available information at the 

time this Conservation Advice was approved; this includes existing plans, records or 

management prescriptions for this species.  



Description 

Verticordia crebra, Family Myrtaceae, also known as Crowded Featherflower, is a spreading 

shrub with few branches that grows to 75 cm high and looks like a miniature pine tree. Leaves 

are dark-green, 15 mm long, fine, pointed and linear, and are crowded over the entire plant. 

Pale-yellow flowers have 3 mm long petals which are mostly hidden by the leaves. A yellow 

style is evident and protrudes to an unusual degree. Flowers are held in the leaf axis and are 

scattered towards the end of the branches. Flowering occurs from May to October (Robinson 

& Coates, 1995; Brown et al., 1998; DEC, 2008). 

Conservation Status 

Verticordia crebra is listed as vulnerable.

 

This species



 

is eligible for listing as vulnerable 

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

Act) as, prior to the commencement of the EPBC Actit was listed as vulnerable under 

Schedule 1 of the Endangered Species Protection Act 1992 (Cwlth). The species is also listed 

as declared rare flora under the Wildlife Conservation Act 1950 (Western Australia).



 

Distribution and Habitat 

Verticordia crebra is endemic to Western Australia and is known from five populations 

within the Fitzgerald River National Park. The total number of plants is estimated to be 4100. 

One population has not been surveyed since its initial discovery in 1981, and plant numbers 

are not recorded for this population. The extent of occurrence is approximately 150 km

2



There are insufficient data to determine the area of occupancy. All populations have 



decreased in size following a fire in 2008 (DEC, 2008).  

Verticordia crebra favours open areas surrounded by scrub and mallee on heavy red loams 

over decomposed spongelite, above and on the slopes of breakaways and near drainage lines. 

Associated species include Comb-leaved Grevillea (Grevillea pectinata), Daviesia sp.Hook-

leaved Mallee (Eucalyptus uncinata), Lerp Mallee (E. incrassata), Purple-leaved Mallee (E. 



pluricaulis subsp. porphyrea), Hibbertia sp., Phebalium rude and Oak-leaved Dryandra 

(Dryandra quercifolia) (Robinson & Coates, 1995; Brown et al., 1998; DEC, 2008). This 

species occurs within the South Coast (Western Australia) Natural Resource Management 

Region. 


The distribution of this species is not known to overlap with any EPBC Act-listed threatened 

ecological community. 



Threats 

The main identified threat to Verticordia crebra is inappropriate fire regimes. Adult plants are 

susceptible to fire in the vegetative and flowering phase, but regenerate well from seed 

(Brown et al., 1998).

Research Priorities 

Research priorities that would inform future regional and local priority actions include: 

 

Undertake survey work in suitable habitat and potential habitat to locate any additional 



populations/occurrences/remnants. 

 



More precisely assess population size, distribution, ecological requirements and the 

relative impacts of threatening processes. 

 

Design and implement a monitoring program or, if appropriate, support and enhance 



existing programs. 

 



Undertake seed germination and/or vegetative propagation trials to determine the 

requirements for successful establishment. 

 

Undertake research into the fire ecology of this species, including identifying the 



appropriate intensity and interval of fire to promote seed germination. 

Regional and Local Priority Actions  

The following regional and local priority recovery and threat abatement actions can be done 

to support the recovery of V. crebra

Habitat Loss, Disturbance and Modification 

 

Monitor known populations to identify key threats. 



 

Monitor the progress of recovery, including the effectiveness of management actions and 



the need to adapt them if necessary. 

 



Minimise adverse impacts from land use at known sites. 

 



Manage any other known, potential or emerging threats. 

Fire 


 

Develop and implement a suitable fire management strategy for V. crebra



 

Provide maps of known occurrences to local and state Rural Fire Services and seek 



inclusion of mitigative measures in bush fire risk management plans, risk register and/or 

operation maps. 

Enable Recovery of Additional Sites and/or Populations 

 



Undertake appropriate seed collection and storage. 

 



Investigate options for linking, enhancing or establishing additional populations. 

 



Implement national translocation protocols (Vallee et al., 2004) if establishing additional 

populations is considered necessary and feasible.  



 

This list does not necessarily encompass all actions that may be of benefit to Crowded 

Featherflower, but highlights those that are considered to be of highest priority at the time of 

preparing the conservation advice.  



Existing Plans/Management Prescriptions that are Relevant to the Species 

 



Wildlife Management Plan No 20, Declared Rare and Poorly Known Flora in the Albany 

District (Robinson & Coates, 1995), and  

 

Fitzgerald River National Park Management Plan 1991–2001 (CALM, 1991). 



These prescriptions were current at the time of publishing; please refer to the relevant 

agency’s website for any updated versions.
