Oakajee Port and Rail OPR Rail Project – Vegetation and Flora Assessment March 2010 172 8.1 FLORA OF NATIONAL AND STATE CONSERVATION SIGNIFICANCE National significance refers to those features of the environment which are recognised under legislation as being of importance to the Australian community; in particular, species listed under the EPBC Act are regarded as nationally significant. State significance refers to those features of the environment that are recognised under State legislation as being of importance to the Western Australian community, in particular, species listed as DRF under the WC Act are of state significance. During the current survey, two flora species of national and state significance were recorded in the Project Area: Caladenia hoffmanii (Endangered, DRF) and Eucalyptus blaxellii (Vulnerable, DRF). During the database searches, an additional two flora species of national and state significance were recorded in the Project Area; Drummondita ericoides (Endangered, DRF) and Philotheca wonganensis (Endangered, DRF). The significance of these species is discussed below. Caladenia hoffmanii is listed as Endangered under the EPBC Act and as DRF under the WC Act. It is endemic to the Geraldton Sandplains bioregion as shown by the current WA HERB distribution for C. hoffmanii in Figure 8.1 below. Figure 8.1 – Distribution of Caladenia hoffmanii Using the information provided in Table 8.2, this species is known from 285 individuals at 38 locations and 19 populations. Of these 52.3% of the total number of plants were inside the Project Area and 1.5% were in conservation reserves. Caladenia hoffmanii grows in clay or sandy‐clay on laterite rocky hill sides and ridges, or in winter wet flats. A disjunct occurrence is recorded 600 km south‐east of the Geraldton area in the Pinharing area, growing around large granite outcrops. These habitats are not widespread in the Project Area and the region and the large percentage of total individuals (52.3%) recorded in the Project Area indicates a high local endemism for this species. The known populations of C. hoffmanii are severely fragmented and the quality of habitat for many populations is in decline (Pers. com. Murray Baker, DEC, 2009). The EPBC Act conservation advice lists the main threats to C. hoffmanii as fire and grazing by feral pigs and rabbits. Due to the fragmentation of the populations, decrease in habitat quality, the small distribution of known occurrences (50 km with one outlier to 70 km), the high percentage of the total population in Oakajee Port and Rail OPR Rail Project – Vegetation and Flora Assessment March 2010 173 the Project Area and the likelihood that it is locally endemic to the area, it is considered that C. hoffmanii has high local significance in the Project Area. Eucalyptus blaxellii is listed as Vulnerable under the EPBC Act and as DRF under the WC Act. It has been recorded in the Geraldton Sandplains and Avon Wheatbelt bioregions as shown by the current WA HERB distribution of E. blaxellii in Figure 8.2 below. Figure 8.2 – Distribution of Eucalyptus blaxellii Using the information provided in Table 8.2, this species is known from 2,885 individuals at 169 locations and 12 populations. Of these 16.4% of the total number of plants were recorded inside the Project Area and 7.6% were in conservation reserves. The EPBC Act conservation advice states the main threat to E. blaxellii is inappropriate fire regimes, however most known populations are secure as they occur in areas that are unsuitable for farming due to the inaccessibility of the steep slope. Eucalyptus blaxellii grows in sand over laterite, or brown clay on sandstone hills or creek flats which is widespread at the Western end of the Project Area. As these habitats are moderately widespread in the region and as the percentage of total individuals is moderate (16.4%) in the Project Area, it indicates a low to moderate local endemism for this species. E. blaxellii does not appear to be locally restricted with records spaning 70 km and one outlier to 170 km. A nomination to remove this species from the listing of DRF was submitted to the Threatened Species Scientific Community earlier in 2009 which has yet to get a decision from the Minister; however it is likely that E. blaxellii’s conservation status maybe altered to a Priority 4 (Pers. com. Murray Baker, DEC, 2009). Because of the large population numbers, longevity, disturbance recovery abilities and the DECs recommendation to remove E. blaxellii from the listing as vulnerable (EPBC Act) and DRF (WC Act), it is considered that E. blaxellii has low conservation significance in the Project Area.
