16/08/02 Darling Riverine Plains Bioregion Background Report in this survey. Introduced species were uncommon with only 17 species recorded from 32% of quadrats. 4.2 SPECIES OF CONSERVATION CONCERN 4.2.1 Threatened and ROTAP species Nineteen threatened species (listed in the schedules of the TSC Act) have been recorded in the DRP, nine of which are endangered (E1) and ten are considered vulnerable (V) (Table 4.2). Nine of these species are also listed as threatened on the EPBC Act. The majority of threatened species records are from the Menindee area with the remainder scattered throughout the bioregion (Map 27). Twenty species are also included on the ROTAP list (Briggs and Leigh 1996, Table 4.2) and four are protected by the National Parks and Wildlife Act 1974 (Table 4.2). Listed endangered species recorded from the Culgoa River floodplain are Capparis loranthifolia var. loranthifolia (narrow-leaf bumble), and Euphorbia sarcostemmoides (climbing caustic). Regionally rare species occurring on the floodplain include Aristida longicollis (bull wiregrass), Acacia coriacea (wirewood), Pluchea dentex (bowl daisy), Phyllanthus carpentariae (hairy spurge) and Pimelea penicillaris (sandplain riceflower) (Environment Australia 2001d). Goodenia macbarronii has been located recently in the Narran Lakes Nature Reserve (Hunter 1999).
