Pomaderris bodalla (a shrub) - vulnerable species listing
The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the shrub Pomaderris bodalla N.G. Walsh & F. Coates as a VULNERABLE SPECIES in Schedule 2 of the Act. Listing of vulnerable species is provided for by Part 2 of the Act.
NSW Scientific Committee - final determination
The Scientific Committee has found that:
1. Pomaderris bodalla (family Rhamnaceae) is described in Harden, G.J. & Murray, L.J. (eds) (2000) Supplement to Flora of NSW Vol 1, University of NSW Press, Sydney, pg. 45, as a shrub 2-4 m high, young stems with spreading rusty simple hairs and dense greyish stellate hairs. Leaves elliptic, broad-elliptic, broad-obovate to + rhombic, mostly 2-3 cm long and 12-15 mm wide, margins entire but + undulate; upper surface dark green and glabrous with veins not or slightly impressed; lower surface pubescent with sparse spreading rusty hairs above short greyish stellate hairs. Flowers cream, in dense panicles. Sepals not persistent in fruit. Petals absent. Capsule and hypanthium stellate-pubescent or with simple hairs obscuring stellate hairs.
2. Pomaderris bodalla is endemic to NSW and is currently known to occur on the south coast between Bodalla and Merimbula, and in the upper Hunter valley near Muswellbrook. On the south coast, it occurs in moist open forest along sheltered gullies or along stream banks. In the upper Hunter valley, it occurs in open forest or woodland on open slopes.
3. There are ten populations of Pomaderris bodalla currently known, and a further two imprecisely described locations from which the species was collected approximately 40 years ago. The majority of populations are small with seven of the populations having estimates of less than a hundred plants each. All populations have locally restricted distributions. The largest known population is in Wollemi National Park and is unlikely to include more than one thousand plants.
4. Pomaderris bodalla is in the conservation reserves of Kooraban National Park on the south coast, and in Wollemi National Park and Wingen Maid Nature Reserve in the north of its range. Other populations on the south coast are located in State Forests and on private land.
5. Pomaderris bodalla is threatened by a number of processes. Two populations are at immediate risk from road maintenance activities and residential development. Two populations on private land are accessible to livestock and may be threatened by trampling, grazing or small-scale clearing activities. All populations may be threatened if fires recur at high frequencies in their habitat, which may result in death of standing plants and depletion of seed banks. Disturbance associated with logging operations on State Forest or private land may also be a threat to some populations of the species. Several populations of P. bodalla are small and therefore subject to declines or extinction related to stochastic events. Clearing of native vegetation and High frequency fire resulting in disruption of life cycle processes in plants and animals and loss of vegetation structure and composition are listed as Key Threatening Processes under the Threatened Species Conservation Act
6. In view of the above the Scientific Committee is of the opinion that Pomaderris bodalla is likely to become endangered in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate.
