Scientific name: Acacia purpureopetala
Acacia purpureopetala is a small shrub with spreading prostrate branches. Branches are angular, becoming terete, and covered in dense white spreading hairs (Pedley 1987). It is distinguished from other Australian Acacia species as it has mauve-pink flower heads (Orchard & Wilson 2001).
Acacia purpureopetala occurs in the Herberton district in the Einasleigh Uplands biogeographic region of north-east Queensland (Orchard & Wilson 2001; Pedley 1987; Queensland Herbarium 2009).
From north to south there are five general locations where this species is found: Mt Emerald south of Walkamin; Stannery Hills; an area near Herberton; Irvinebank; and along the Misery-Coolgara Road, north-east of Mt Garnet (Queensland Herbarium 2009). This species had been collected at all five locations between 2004-2009 (Queensland Herbarium 2009).
The species' extent of occurrence and area of occupancy are estimated to be 902 km2 and less than 0.1 km2 respectively (Queensland Herbarium 2009).
Total population extent
Acacia purpureopetala is known from ten populations (Queensland Herbarium 2009). The estimated total population figure for A. purpureopetala is 500 individuals (McDonald 2009 pers. comm.). The numbers of individual plants at each site are small (approximately <5-100).
The following Table (1) provides estimates for the numbers of individuals at each site.
Table 1: Population data (McDonald 2009 pers. comm.; Queensland Herbarium 2009)
|Location||Population||Number of plants at each site|
|1. Mt Emerald||1. South of Walkamin||40|
|2. Stannery Hills||2. You and Me Mine||100|
|3. North of Stannary Hills||Unknown|
|3. Herberton||4. Near Herberton||12|
|4. Irvinebank||5. Jumna Mine||100|
|6. Ibis Dam||100|
|5. North-east of Mt Garnet||7. Mt Misery||11|
|8. Along the Mt Misery-Coolgara road||<5|
|9. Along the Mt Misery-Coolgara road||<5|
|10. Along the Mt Misery-Coolgara road||<5|
Populations appear stable, with the exception of the Jumna Mine population which was impacted by road works prior to 2009 (McDonald 2009 pers. comm.). All populations are considered neccessary for the long-term survival of A. purpureopetala (McDonald 2009 pers. comm.).
No populations are known to occur in reserves (Queensland Herbarium 2009). There are no captive populations of this species, although the establishment of extra populations has been discussed, such as at Bush Heritage Yourka Station (Baker-Gabb & Sheppard 2007).
Acacia purpureopetala grows on steep rocky slopes, usually at altitudes of 780-880 m above sea level in eucalypt woodland (Orchard & Wilson 2001; Queensland Herbarium 2009).
Near Mt Emerald, south-west of Walkamin, this species is found in a mosaic of heathland and woodland. Associated species are Ramornie Stringybark (Eucalyptus tindaliae), E. pachycalyx, Range Bloodwood (Eucalyptus abergiana), Homoranthus porteri and Leptospermum amboinense (Queensland Herbarium 2009).
At Stannary Hills, A. purpureopetala is found on the hilltop, on very steep loose rocky slopes and excavated rock surfaces on metamorphics, in open woodland with eucalypt woodland and sparse herbaceous flora (Queensland Herbarium 2009).
At the Herberton site, this species occurs on steep rocky hillsides and stone slopes in open forest of Eucalyptus rhodops and E. medicris woodland (Queensland Herbarium 2009).
In the Irvinebank area, it occurs on roadsides and disturbed situations within woodland where the associated species are Gympie Messmate (Eucalyptus cloeziana), White Bloodwood (Corymbia trachyphloia), Acacia calyculata, A. humifusa and A. leptoloba and steep rocky slopes carrying Narrow Leaved Ironbark (Eucalyptus crebra) woodland (Queensland Herbarium 2009).
Along the Mt Misery to Coolgara road it occurs in disturbed eucalypt woodland on rocky outcrops on low granite hills (Queensland herbarium 2009).
Acacia purpureopetala is known to flower mainly between May and September, with sporadic flowering at other times (Queensland Herbarium 2009).
This species has been recorded as occurring on disturbed sites in the Irvinebank area and therefore may require disturbance such as fire for reproduction (Queensland Herbarium 2009).
Habitat clearance, disturbance and direct removal
Mining is a past threat to A. purpureopetala, as three of the five known locations have been subject to mining operations. Mining is considered likely to be a future threat to this species (McDonald 2009 pers. comm.).
Roadworks and infrastructure maintenance, such as powerline easements are a current and continuing threat to this species (Queensland Herbarium 2009). Pre-2009 road widening had removed part of the population at the Irvinebank location (McDonald 2009 pers. comm.). Seed collection for horticulture may be a threat, given the desirabililty for this species when in flower. A lack of germination from illegally collected seed may lead to the collection of seedlings (McDonald 2009 pers. comm.).
Minister's reasons for recovery plan decision
There should not be a recovery plan for A. purpureopetala at this time as the approved conservation advice for the species provides sufficient direction to implement priority actions and mitigate against key threats.
Recovery actions are identified in the Commonwealth conservation advice
Refer to the Commonwealth Conservation Advice on Acacia purpureopetala (TSSC 2008gl) for information on research priorities and recovery priority actions to mitigate threats including habitat loss, disturbance and modification. Raising awareness and undertaking further survey work of the species are also encouraged in the Advice.
Management documents identified for Acacia purpureopetala include:
- Revegetation Guidelines and Recommendations for Gibbs Creek, Irvinebank (Gleed 2005)
- Northern Gulf Region: Natural Resource Management Plan 2008-2013 (Northern Gulf Resource Management Group 2008)
The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
