Denman Pomaderris was described as a new species in 1997 (Walsh & Coates 1997).

Denman Pomaderris is a shrub growing 1 to 3 metres high, with densely hairy young stems. The leaves are broadly oval in shape, 1 to 3.5 cm long, 8 to 20 mm wide, with a green upper surface that is velvety with short simple hairs. The lower leaf surface has longer hairs and prominent raised secondary and tertiary veins. Flowers are creamish, and borne in short dense panicles. Petals are usually absent (rarely one to three per flower) (DECC 2005).

Denman Pomaderris has been recorded from a small number of sites along a single ridgeline near Denman in the upper Hunter Valley (Muswellbrook local government area) (DECC 2005; NSW SC 2002).

Extensive vegetation surveys in the nearby Goulburn River National Park, Wollemi National Park, Manobalai Nature Reserve and Crown land did not locate any additional populations of the Denman Pomaderris (Bell 2001).

The Denman Pomaderris population occurs just to the west of Denman, where plants are scattered over an area of 1 ha (Walsh & Coates 1997), and another population occurs approximately 4 km north of the type population (Bell 2001). The total size of these two populations is less than 100 individuals (Bell 2001).

Denman Pomaderris is not known to occur in any conservation reserve (NSW SC 2002).

Denman Pomaderris occupies woodland in association with Eucalyptus crebra, E. blakelyi, Notelaea microcarpa, and Allocasuarina littoralis. It is associated with sandy loam soils on sandstone or conglomerate (DECC 2005; NSW SC 2002).

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 (NSW SC 2002; DECC 2005).

Minister's reasons for recovery plan decision
The approved conservation advice for the species now provides sufficient direction to implement priority actions and mitigate against key threats. A recovery plan is not considered to be necessary at this time.

The Department of Environment and Conservation (2005) recommends the following recovery strategies to help recover the Denman Pomaderris in NSW:

  • determine the need for an ex-situ conservation program,

  • protect areas of known and potential habitat from clearing,

  • monitor the health of the population at known sites,

  • map known sites and conduct surveys of potential habitat to locate new sites.

The Department of Environment and Conservation (2005a) has identified 11 priority actions to help recover the Denman Pomaderris in NSW:

  • survey recorded sites to determine status and document threats,

  • collect seed for NSW Seedbank. Develop collection program in collaboration with the Royal Botanic Gardens Trust - all known provenances (conservation collection),

  • investigate seed viability, germination, dormancy and longevity (in natural environment and in storage),

  • liaise with land managers to ensure the effective implementation of threat abatement measures,

  • record location of sites accurately on the NSW Wildlife Atlas,

  • prepare site management plans for extant sites, in consultation with land managers,

  • prepare profile and EIA guidelines,

  • seek to increase the level of legislative protection for freehold sites through land-use planning mechanisms and conservation agreements,

  • monitor population size and health,

  • undertake management-focussed ecological research,

  • identify, map and survey potential habitat.

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
