Darwinia peduncularis (a shrub) - vulnerable species listing

The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the shrub Darwinia peduncularis B. Briggs as a VULNERABLE SPECIES on Schedule 2 of the Threatened Species Conservation Act. Listing is provided for by Part 2 of the Act.

NSW Scientific Committee - final determination

The Scientific Committee has found that:

1. Darwinia peduncularis (family Myrtaceae) is a divaricate shrub that grows in dry sclerophyll forest on sandstone hillsides and ridges. A detailed description is provided in Harden, G. 1991. Flora of New South Wales Volume 2 UNSW Press, Sydney. p. 191.

2. Darwinia peduncularis occurs as local disjunct populations in coastal New South Wales with a couple of isolated populations in the Blue Mountains. It has been recorded from Brooklyn, Berowra, Galston Gorge, Hornsby, Bargo River, Glen Davis, Mount Boonbourwa and Kings Tableland. Some populations are within the Marramarra National Park, Wollemi National Park, Blue Mountains National Park and Berowra Valley Regional Park.

3. Local populations are small with a total population likely to be less than 2500 and possibly less than 1500. The species appears to be vulnerable to fire and disturbance and little is known about its recovery from either.

4. Populations are vulnerable due to small population sizes and are threatened by altered fire regimes, trail bikes, inappropriate or overused walking trails and weed invasion.

5. In view of 3, & 4 above the Scientific Committee is of the opinion that Darwinia peduncularis is likely to become endangered in nature in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate, and it is therefore eligible for listing as a vulnerable species.

Proposed Gazettal date: 12/3/99
Exhibition period: 12/3/99 - 16/4/99

The NSW Threatened Species Scientific Committee undertook a review of this species in 2022 and found that the threat status is unchanged. The Conservation assessment report may be downloaded: Conservation assessment report Darwinia peduncularis (PDF 375KB).
