| 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)
Reason for Conservation Assessment by the Committee This advice follows assessment of new information provided through the Species Information Partnership with Western Australia on:
Summary of Species Details Taxonomy Conventionally accepted as Verticordia apecta (George and George, 1994).
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).
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).
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).
Land clearing (DEC, 2009).
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).

Listing Advice Page 1 of 4 The Minister included this species in the critically endangered category, effective from 19 August 2010 3. 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
Reduction in numbers No data.
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).
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. OR Verticordia apecta (Hay River Featherflower)
Listing Advice Page 2 of 4 The Minister included this species in the critically endangered category, effective from 19 August 2010
Total no. of mature individuals AND
Very low – 16 mature plants (DEC, 2009).
Continued decline likely AND Yes – see Criterion 2. Geographic distribution precarious Yes – see Criterion 2.
The estimated total number of mature individuals is extremely low, very low or low
Total no. of mature individuals Extremely low – 16 mature plants (DEC, 2009).
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
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.
(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.
