Scientific name: Pomaderris pallida
Profile last updated:
14 Oct 2024
Description
Pale Pomaderris is a compact, rounded shrub to 1.5 m tall. Its small leaves may be narrow or oval in shape, and up to 18 mm long and 7 mm wide. Both leaf-surfaces are covered in a dense mat of soft, star-shaped hairs. The upper surface is pale green and the lower surface is greyish-white. The flowers are pale yellow, small, and have five sepals which are petal-like structures (there are no true petals). The flowers are on short stalks and arranged in clusters in the angles where the leaves meet the stem (axils) towards the ends of the outer branchlets. The fruits are small, dry, three-chambered capsules. Flowering occurs from mid September to December.
Distribution
Pale Pomaderris has been recorded from near Kydra Trig (north-west of Nimmitabel), Tinderry Nature Reserve, the Queanbeyan River (near Queanbeyan), the Shoalhaven River (between Bungonia and Warri), the Murrumbidgee River west of the ACT and the Byadbo area in Kosciuszko National Park. It is also found along the Murrumbidgee River in the ACT and has been recently recorded in eastern Victoria.
Habitat and ecology
- This species usually grows in shrub communities surrounded by Brittle Gum (Eucalyptus mannifera) and Red Stringybark (E. macrorhyncha) or Callitris spp. woodland.

Threats
- The Queanbeyan River population is threatened by rural residential development.
- Browsing and/or trampling by deer, horses, possibly goats and rabbits.
- Some Pomaderris species are fire-sensitive. Frequent fires and cool hazard reduction burns will potentially eliminate populations.
- Invasion of habitat by weeds.
- Sediment runoff from the fire trail
- Grazing by cattle, sheep and kangaroos. Goats also present.
- Potential for impacts of development to affect the small portion of the site not secured on a conservation agreement property.
- Isolated small populations are likely to have low genetic diversity, and be at higher risk of loss from stochastic events.
- Smaller riparian populations may be subject to loss of mature individuals through flood damage. Frequent flooding may disrupt the lifecycle to the extent that the soil seedbank may be affected.
- Lack of knowledge regarding dormancy thresholds, seed vigour and seedling and plant performance for this species, which is known to be triploid.
- Browsing/grazing by swamp wallaby
- Inappropriate fire regime required to sustain natural recruitment varying from too frequent fire to lack of fire, and too cool a temperature.
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
- Negotiate with landowners of Queanbeyan River population to ensure habitat protection and weed control that doesn't impact on Pale Pomaderris plants.
- Ensure that personnel planning and undertaking hazard reduction burns are able to identify the species and are aware of its habitat.
- Control goats at Kydra.
- Following burning, protect populations (where possible) from further fires until plants have reached reproductive maturity.
- Ensure that Queanbeyan City Council considers this species (and seeks survey for it) in developments along the Queanbeyan River.
