Scientific name: Pomaderris delicata

Conservation status in NSW: Critically Endangered

Commonwealth status: Critically Endangered

Gazetted date: 16 Jul 2010

Profile last updated: 30 Jul 2024

Description

Delicate Pomaderris is a shrub 1 - 2 m tall. Its leaves are ellipse-shaped (to 3 cm long and 1.5 cm wide). The under-surfaces of leaves are covered with grey star-shaped hairs and a few simple hairs on the veins. The spring flowers are golden yellow and have petals (unlike some other Pomaderris species).

This species has been confirmed as susceptible to the plant pathogen Phytophthora cinnamomi, with deaths observed in at least one population. Care should be taken to ensure nil Phytophthora transfer by not transferring soil (e.g. mud fragments on boots) into any sites containing this species.

Distribution

Delicate Pomaderris is known from only two sites; between Goulburn and Bungonia and south of Windellama (Cullula).

Habitat and ecology

At both known sites the Delicate Pomaderris grows in dry open forest dominated by Eucalyptus sieberi with a dense she-oak understorey. Soils are shallow and derived from sandstone and siltstone. Nothing is known about the response of the species to fire and other disturbance.

Threats

Habitat disturbance during road and infrastructure construction and maintenance.
This species occupies a small area and could potentially be impacted by a range of disturbances.
The response of the species to fire is unknown.
Clearing of understorey may affect populations on private land.
There is potential for incursions from cattle, sheep, feral goats and various weeds from private lands adjacent to suitable habitat.
Wild populations are susceptible to effects of Phytophthora cinnamomi.

Recovery strategies

A targeted strategy for managing this species has been developed under the Saving Our Species program; click here for details. For more information on the Saving Our Species program click here

Activities to assist this species

Ensure that personnel planning and undertaking hazard reduction burns are able to identify the species and are aware of its habitat.
Following burning, protect populations (where possible) from further fires until plants have reached reproductive maturity.
Full assessment should be undertaken of any development or activity on land in vicinity of the species.
Clearly mark both roadside parts of populations and ensure that council workers are aware of the plants.
Fully protect both populations - no loss of plants should be an aim of conservation of this species.
Roadside populations and potential habitat should be marked onto maps used for planning works.
Conduct further surveys in an effort to locate more Delicate Pomaderris sites.
Mark Delicate Pomaderris sites and potential habitat onto maps used for planning hazard reduction work.
