Scientific name: Homoranthus bornhardtiensis
Gazetted date:
23 Jul 1999
Profile last updated:
22 Mar 2021
Description
This species was omitted from the TSC Act in November 2011, after a taxonomic review concluded that it was a synonym of H. prolixus. A phenetic analysis between the plants, H. prolixus and H. bornhardtiensis showed no clear discontinuties based on morphology.
Distribution
Known only from Ironbark Nature Reserve and neighbouring properties, north-east of Barraba.
Habitat and ecology
- Flowers from October to November.
- Occurs in open and exposed sites in shrubland and low woodland on granite outcrops between 650 - 970 m altitude. Often grows in rock crevices on bare rocky slopes and in the surrounding shallow soils.
- Associated species include Callitris endlicheri, Eucalyptus prava, Eucalyptus caleyi, Acacia cheelii, Acacia neriifolia, Calytrix tetragona, Leucopogon neoanglicus, Ozothamnus obcordatus, Leptospermum novae-angliae, Cryptandra amara var. floribunda, Prostanthera howelliae and Boronia anethifolia.
- Likely to be highly fire-sensitive and intolerant to frequent fire disturbance.
- At the time of its initial survey, the known distribution of Homoranthus bornhardtiensis was restricted to an area of six by seven kilometres. Plant abundances within populations are not known.

Threats
- Trampling and soil compaction by feral goats.
- Risk of extinction through localised catastrophic events such as fire is high, due to the restricted species distribution and low population numbers.
- Grazing by feral goats and rabbits.
Recovery strategies
A Saving Our Species conservation project is currently being developed for this species and will be available soon. For information on how you can contribute to this species' recovery, see the Activities to assist this species section below.
Activities to assist this species
- Assist with the control of feral goats.
- Protect areas of known and potential habitat from clearing and fragmentation.
- Protect areas of habitat from frequent fire.
- Report new records of Barraba Homoranthus to the DEC.
