Scientific name: Daphnandra johnsonii
Profile last updated:
14 Oct 2024
Description
Rainforest tree to 20 metres tall. Leaves opposite, coarsely toothed, roughly oval in shape, 6 to 12 cm long, 1.5 to 6 cm wide, with a raised mid-vein on the upper surface. Small, pale greenish white flowers (rarely with a pink margin), borne in a many-flowered panicle from the leaf base.
Distribution
Restricted to the Illawarra region where it has been recorded from the local government areas of Shoalhaven, Kiama, Shellharbour and Wollongong.
Habitat and ecology
- Occupies the rocky hillsides and gullies of the Illawarra lowlands, occasionally extending onto the upper escarpment slopes.
- Associated vegetation includes rainforest and moist eucalypt forest.
- Associated soils are loams and clay loams derived from volcanic and fertile sedimentary rocks.
- Flowers briefly in September and early October with fruits taking 10 to 12 months to mature.
- Capable of vegetative reproduction from stems (coppicing) and rhizomes (suckering).
- Low levels of seed production are suspected, with stems at most sites appearing to only produce ‘pseudo-fruit’ which lack seeds.
- Possibly killed by fire.

Threats
- Further loss and fragmentation of habitat, particularly as a consequence of clearing for agriculture, hobby farming, and residential development.
- Habitat degradation as a consequence of weed invasion, altered hydrological conditions and rubbish dumping.
- Low levels of seed production.
- Deer and other pest species browsing the species.
- Weed incursions, including Lantana and Cape Ivy.
- Grazing and trampling by livestock preventing seedling establishment.
- Quarrying the area.
Recovery strategies
Priority actions are the specific, practical things that must be done to recover a threatened species, population or ecological
community. The Office of Environment and Heritage has identified
25 priority actions
to help recover the Illawarra Socketwood in New South Wales.
Activities to assist this species
- Manage sites to exclude fire.
- Consider off-site impacts (including changes to groundwater hydrology) in the assessment of nearby developments.
- Install fencing to exclude livestock and machinery.
- Protect areas of known and potential habitat from clearing and further fragmentation.
- Restore degraded habitat using bush regeneration techniques.
- Map known sites and conduct surveys of potential habitat to locate new sites.
