Approved Conservation Advice for 



Verticordia apecta (Hay River Featherflower) 

(s266B of the Environment Protection and Biodiversity Conservation Act 1999

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 apecta, Family Myrtaceae, also known as Hay River Featherflower or Scruffy 

Verticordia, is a slender, erect shrub with one stem that can grow to 0.45 m high. The lower 

leaves are linear, three-sided, rounded at the end and 3–9 mm long. The stem leaves are 

narrowly elliptic, rounded at the end and 7 mm long. The petals are deep pink, the finer fringe 

lobes white, and 4 mm long. Flowering has been observed in November (George and George, 

1994; Western Australian Herbarium, 2006). 

Hay River Featherflower is similar to V. habrantha (Hidden Featherflower) in habit, leaves 

and floral arrangement, but the shortly bearded style and fimbriate, pink petals readily 

distinguish it from that species (George and George, 1994). 

Conservation Status 

Hay River Featherflower is listed as critically endangered. This species is eligible for listing 

as critically endangered under the Environment Protection and Biodiversity Conservation Act 

1999 (Cwlth) (EPBC Act) as the estimated total number of mature individuals is extremely 

low, and it has a very restricted geographic distribution which is precarious for its survival 

given the nature of ongoing threats (TSSC, 2009). 

Hay River Featherflower is also listed as declared rare flora under the Western Australian 



Wildlife Conservation Act 1950, and is managed as critically endangered (according to IUCN 

criteria) by the Western Australian Government. 



Distribution and Habitat 

Hay River Featherflower is endemic to Western Australia. It is known from a single 

population in the Mt Barker area, approximately 400 km south-east of Perth (DEC, 2009). 

The extent of occurrence of the species is approximately 100 m

2

 (10 m x 10 m) and its area of 



occupancy is approximately 8 m

2

. The species occurs on Crown Land in State Forest, which 



is proposed National Park (DEC, 2009).  

The population size of the species is estimated to be 16 mature plants. This figure was 

calculated using counts of plants from population surveys undertaken in October 2008 (DEC, 

2009). 


Hay River Featherflower 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 occurs within the Jarrah Forest IBRA Bioregion and the South Coast 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 threats to the species are inappropriate fire regimes (too frequent fire) 

which may affect the long-term viability of the species, and dieback caused by 



Phytophthora cinnamomi, which is currently suspected at the location of the only known 

population (DEC, 2009).  



Research Priorities 

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

 

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



existing programs. 

 



More precisely assess population size, geographic distribution, ecological requirements, 

and the relevant impacts of threatening processes, including: 

o

 

factors that influence the level of flowering, pollination, seed production and fruit 



development for the species 

o

 



the pollination biology of the species and the requirements of pollinators 

o

 



longevity of plants and time taken to reach reproductive maturity 

o

 



the reproductive strategies, phenology and seasonal growth of the species 

o

 



the species’ response to disturbance (e.g. fire, smoke and slashing) 

o

 



impacts of dieback caused by P. cinnamomi on Hay River Featherflower and its 

habitat 


o

 

other relevant mortality and morphological data for the species. 



 

Undertake survey work in suitable habitat and potential habitat during the November 



flowering period to locate any additional populations/occurrences/remnants. 

 



Undertake seed germination trials to determine the requirements for successful 

establishment. 

 

Identify appropriate intensity and interval of fire to promote seed germination. 



Priority Actions 

The following priority recovery and threat abatement actions can be done to support the 

recovery of Hay River Featherflower. 

Habitat Loss, Disturbance and Modification 

 

Monitor known population to identify key threats. 



 

Ensure there is no disturbance in areas where Hay River Featherflower occurs, excluding 



necessary actions to manage the conservation of the species. 

 



Control access routes to suitably constrain public access to known sites on public land. 

 



Investigate inclusion in reserve tenure if possible. 

 



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

the need to adapt them if necessary. 

Fire 



 



Develop and implement a suitable fire management strategy for the habitat of Hay River 

Featherflower. 

 

Where appropriate, 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. 

Diseases, Fungi and Parasites 

 



Develop and implement suitable hygiene protocols to protect known sites from further 

outbreaks of dieback caused by P. cinnamomi

 

If necessary, implement appropriate management actions to minimise the adverse impacts 



of existing P. cinnamomi infestations.

Conservation Information 

 

Raise awareness of Hay River Featherflower within the local community. 



 

Frequently engage with land managers responsible for the land on which the population 



occurs and encourage these key stakeholders to contribute to the implementation of 

conservation management actions. 

Enable Recovery of Additional Sites and/or Populations 

 



Undertake appropriate seed collection and storage. 

 



Investigate options for 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 Hay River 



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

preparing the Conservation Advice.
