Parks Victoria Technical Series No. 79 Flinders and Twofold Shelf Bioregions Marine Natural Values Study Figure 21. Sponge garden in Point Hicks Marine National Park. Photo by Mark Norman Museum of Victoria. 2.3.3 MARINE ECOLOGICAL COMMUNITIES General Since the first <strong>natural</strong> <strong>values</strong> report by Plummer et al. (2003) Parks Victoria has invested in extensive monitoring and mapping surveys in Point Hicks MNP. There has been broadscale habitat mapping, with the intertidal and shallow subtidal areas mapped from aerial and satellite imagery (Ball and Blake 2007) and the deep subtidal areas with hydroacoustic surveys (Holmes et al. 2007a). There have been four SRMP surveys of the shallow subtidal reef biota of Cape Howe which are summarised by Williams et al. (2007) and Edmunds et al. (2010b). Additional funding has allowed samples from deep subtidal soft sediment surveyed in the MNP in 1998 to be processed and identified (Heislers and Parry 2007). There have still been no surveys of sandy beaches, the biota of intertidal reefs or the pelagic habitats. Important locations for some birds and mammals are shown in Figure 20. Surveys in the MNP found red and brown algae dominate the diversity of macrophytes, gastropods and echinoderms the invertebrates and fish and birds the vertebrates in Point Hicks MNP (Table 15, Appendix 1). 51
