Scientific name: Brachyscome ascendens

Conservation status in NSW: Endangered

Commonwealth status: Not listed

Gazetted date: 13 Jul 2001

Description

This perennial daisy grows up to 30 cm tall. The toothed leaves have two to eight lobes and are up to 28 mm long by 8 mm wide. The flower is lavender with a yellow centre.

Distribution

Restricted to south-east Queensland and north-east NSW. Currently known from only one location in NSW, on the Tweed Escarpment in the Border Ranges National Park. Additional populations may occur at other clifftop sites along the Tweed Escarpment.

Habitat and ecology

Montane shrubland on clifftops and benches in thin, rocky soils of basaltic origin.

South Eastern Queensland

Threats

Risk of local extinction because of small population.
Invasion of weeds such as Mistflower (Ageratina riparia) and Crofton Weed (Ageratina adenophora).
Disturbance associated with construction and maintenance of walking track and viewing platform.
Trampling of plants by bushwalkers and other visitors to the site.
Insufficient understanding of distribution.
Lack of knowledge about the habitat requirements, population size and threats to the species.
Inappropriate fire regimes (too severe and too intense) including risk from uncontrolled fires due to lightning strikes and ecological burning for other plant species of significance which are fire ephemeral.
Restricted distribution may increase the species susceptibility to climate change impacts (including drought and increased fire intensity and frequency) reducing soil moisture for plants. Very little information is known about the species climate response.

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 4 priority actions to help recover the Border Ranges Daisy in New South Wales.

Activities to assist this species

Stay on formed tracks when visiting national parks.
View and photograph native wildflowers but leave them where they are.
Identify areas of habitat and protect them during track-works.
Control weeds in potential habitat
Notify the OEH of any new occurrences of the Border Ranges Daisy.
