Conservation status in NSW: Endangered

Commonwealth status: Endangered

Profile last updated: 29 Nov 2022

Description

The Granite Rose is a shrub that grows to 1.5 m tall. Young branchlets are smooth or warty and, like the leaves, may be covered with white star-shaped hairs. The leaves are 4 - 18 mm long and 1 - 4 mm wide with conspicuous oil glands and a paler underside. The leaves have very small rounded teeth along the margins which are curved under and are arranged oppositely along the stem. Flowers are pale to bright pink or occasionally white, with four triangular petals, and are present from July until November. The fruit is a brown or black dry capsule 4–6 cm long and 2.5–3.5 cm wide.

Distribution

Restricted to a small area of the 'granite belt' near Stanthorpe in south-eastern Queensland and a nearby area in NSW adjacent to the border.

Habitat and ecology

The species occurs in sandy soils derived from granite, within heathy dry sclerophyll forest.
Associated species include Allocasuarina spp., Boronia anemonifolia, Cryptandra spp., Daviesia spp., Eriostemon myoporoides subsp. epilosus, Eucalyptus andrewsii and Exocarpus spp.
Pollinators include several species of Heliozelid moths.
Flowers mainly from July until November.
Plants resprout following fire.

Threats

Vegetation clearing, including under-scrubbing, for agricultural and fire reduction purposes.
Current and potential future land management practices do not support conservation.
The species is susceptible to extinction via stochastic processes due to its small known population size and restricted distribution.
Plantation establishment and other forestry related activities.
Quarrying and associated roadworks.
Inappropriate fire regime as a result of frequent agricultural burning.
Illegal dumping.
Low seed viability.
Road works.
Weed invasion.
Grazing by domestic stock
Unauthorised collection of seeds or cuttings and picking of reproductive material (flowers).
Grazing by feral goats.
Lack of information regarding the population distribution.

Activities to assist this species

Assess the population at the recently confirmed site and identify additional populations by undertaking survey.
Protect known populations from disturbance by erecting fencing and installing signage.
Implement appropriate fire regime for habitat type with frequency of 5-50 years and some intervals of greater than 25 years.
Undertake research into the species response for fire and reproductive strategies.
Identify the full range of threats to the species.
Undertake weed control at known sites.
Ensure feral herbivor control is implemented at know sites.
Ensure viable seed bank is stored ex-situ.
Monitor population dynamics and threats.
