Pomaderris reperta (a shrub) - endangered species listing

NSW Scientific Committee - final determination

The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the shrub Pomaderris reperta N.G. Walsh & F. Coates as an ENDANGERED SPECIES in Part 1 of Schedule 1 of the Act. Listing of endangered species is provided for by Part 2 of the Act.

The Scientific Committee has found that:

1. Pomaderris reperta N.G. Walsh & F. Coates (family Rhamnaceae), was described in 1997.

2. Pomaderris reperta N.G. Walsh & F. Coates is described by G. J. Harden (2000) in G.J. Harden & L.J. Murray (eds) (2000) Supplement to Flora of NSW Vol. 1,p. 49, University of NSW Press, as: Shrub 1-3 m high, young stems densely villous with rusty simple and stellate hairs simple. Leaves ovate to broad-ovate, elliptic to broad-elliptic or obovate to broad-obovate, 1-3.5 cm long, 8-20 mm wide, apex usually rounded to emarginate; upper surface green, velvety with short simple hairs; lower surface pubescent with loosely appressed or spreading pale and rusty simple hairs over dense white or greyish stellate hairs; secondary and tertiary veins raised and prominent on the lower surface; stipules 3-5 mm long, shed early. Flowers creamish, in short dense panicles. Sepals not persistent in fruit. Petals usually absent (rarely 1-3 per flower). Capsule not seen; hypanthium and ovary with simple hairs, sepals with short stellate hairs. Grows in dry sclerophyll woodland. [included in Pomaderris species D in Flora of NSW (1990)].

3. Pomaderris reperta is currently known from a single ridgeline near Denman in the upper Hunter Valley. It grows in Eucalyptus crebra - E. blakelyi woodland on sandy loam. It is not known from any conservation reserve.

4. The main threats to the species are low population numbers and restricted distribution, both of which make the species susceptible to demographic and environmental stochasticity.

In view of the above the Scientific Committee is of the opinion that Pomaderris reperta N.G. Walsh & F. Coates is likely to become extinct in nature in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate.
