Introduction 1.1 Site The Northern Agricultural Region (NAR) covers an approximately 7.5 million hectare area of Western Australia, spanning the coastline between Gingin to the south and Kalbarri to the north. The coastline and waters that form part of the region, as identified in Figure 1.1, feature over 150 islands. The majority of these islands are part of either the Houtman-Abrolhos Group (Abrolhos) or the Turquoise Coast Island Nature Reserves (Turquoise Coast NR) and are significant sites of natural resource management investment - including revegetation/invasive flora and fauna control and feral-free sanctuaries for threatened species such as Dibblers and Australian Sea Lions. Figure 1.1 The Northern Agricultural Region Area m p rogers & associates pl NACC, Coastal Hazard Assessment of Islands in the NAR K1516, Report R1009 Rev 0, Page 1 Given the close proximity and susceptibility to coastal processes, the risks posed to natural resources on the NAR islands from coastal hazards both now and into the future need to be considered. It is especially important to understand how changes to the climate system and projected sea level rise may impact the islands over the relevant planning timeframe. Within Western Australia, State Planning Policy 2.6 State Coastal Planning Policy (SPP2.6, WAPC 2013) provides guidance on the assessment of coastal hazard risks for infrastructure as well as natural assets located in close proximity to the coast. This guidance is in the form of a methodology to assess the potential extent of coastal hazard impacts. To provide guidance regarding the risks posed by coastal hazards, the Northern Agricultural Catchments Council (NACC) engaged specialist coastal and port engineers, M P Rogers & Associates (MRA), to prepare a coastal hazard assessment for the islands within the NAR. NACC is one of Australia’s 56 regional Natural Resource Management (NRM) organisations working to accomplish nation-wide management, restoration and protection of Australia’s natural environment by addressing national environmental priorities at the regional level. The outcomes of this assessment, in conjunction with the ecological requirements of target conservation species, will aid natural resource managers in determining the timeframes for which specific islands may become unsuitable for maintaining these species. This will in turn, guide future NRM investment decisions within the NAR. A total of 30 islands in the NAR (22 in the Abrolhos and 8 in the Turquoise Coast NR) were identified by manager stakeholders as having significant terrestrial NRM values at risk from coastal hazards. The coastal inundation and erosion assessments in Sections 2 and 3 as well as the coastal hazard mapping in Section 4 focusses on the 30 islands, as listed (south to north) in Table 1.1. m p rogers & associates pl NACC, Coastal Hazard Assessment of Islands in the NAR K1516, Report R1009 Rev 0, Page 2 Table 1.1 NAR Islands Location Island Location Lancelin Island Lancelin, Turquoise Coast NR Wedge Island Wedge Island, Turquoise Coast NR South Green Island Grey, Turquoise Coast NR North Green Island Escape Island Whitlock Island Jurien Bay, Turquoise Coast NR Boullanger Island Favorite Island Pelsaert Island Middle Island Gun Island Stick Island Leo Island Alexander Island Serventy Island Campbell Island Suomi Island Keru Island Wooded Island Abrolhos Islands Morley Island Rat Island Little Rat Island Long Island Beacon Island West Wallabi Island East Wallabi Island Pigeon Island Seagull Island Tattler Island North Island m p rogers & associates pl NACC, Coastal Hazard Assessment of Islands in the NAR K1516, Report R1009 Rev 0, Page 3 It is important to recognise the differences in assessing natural flora and fauna resources on offshore islands, compared to developed sections of mainland coastlines. The Turquoise Coast NR islands listed are completely uninhabited and do not contain any developed infrastructure. Human influence on these islands is limited to temporary visitors on suitable boating days. A number of the Abrolhos islands listed, including Pigeon, Little Rat, Rat and East Wallabi islands, have minimal infrastructure - generally limited to fisherman shacks, private mooring jetties and a single airport runway. Fisherman might stay for periods of time seasonally, however there is no public accommodation on the islands for visitors. Visitors are allowed to moor overnight at several locations or day trip to the islands by boat or plane, either privately or via several local charters who operate out of Geraldton. The difficulty in accessing the islands, approximately 60 km offshore, means that they are generally only accessed by experienced boaters, fisherman and charter operators. This helps to reduce the risks of public safety issues on the islands. The consequences, and therefore risks, are much lower for the natural resources assessed in following Sections of this report. The fact that significant and widespread vegetation can be identified throughout the islands today, shows that flora and fauna has historically and can potentially, over the 100 year planning timeframe, survive severe storm events. It is vital that this is considered in analysing the coastal hazard assessment and subsequent maps presented in this report. This is particularly significant as the SPP2.6 methodology should not be viewed as a prediction of future shoreline location, but rather should be viewed to provide a conservative assessment of land areas that could potentially be impacted by coastal processes over the relevant planning horizons. This coastal hazard assessment will provide a first pass assessment of the potential areas that could be impacted by inundation and erosion over a range of timeframes up to and including the “long term” 100 year planning timeframe to the year 2118 as required by SPP2.6.

DECEMBER 1960 BERMUDA: A PARTIALLY DROWNED, LATE MATURE, PLEISTOCENE KARST BY J HARLEN BRETZ ABSTRACT During Pleistocene time, the Bermuda Islands repeatedly underwent partial inundation and re-emergence. The land areas were continuously attacked and reduced by rain and ground water but repeatedly renewed, during times of submergence, by deposition of marine limestone and by contemporaneous additions of shore-born and wind-transported carbonate sand, now eolianite. Soils formed under subaerial conditions are now buried be- neath later deposits and constitute important stratigraphic markers. The igneous founda- tion rock appears to have been exposed during some low marine stands, and the former shore lines seem to be recorded by submerged terraces. The major karst features are largely below sea level, and they must date from times of continental glaciations. Previous writers have assigned eolian accumulation to times of Pleistocene low sea level and soil-making to times of interglacial high sea. Both conclusions are held to be er- roneous.

  • Herpetofauna Assessment of Long Island, Wallabi Group – 8 November 2005
    Herpetofauna of Long Island, Houtman Abrolhos Herpetofauna Assessment of Long Island, Wallabi Group – 8 November 2005 Prepared for: MBS Environmental By: Dr R. A. How Western Australian Museum Locked Bag 49 Welshpool DC, WA 6986 Phone: (08) 9427 2738 Facsimile: (08) 9427 2882 November 2005 Report No: NTVBE/2005/MBS Western Australian Museum 1 Herpetofauna of Long Island, Houtman Abrolhos Introduction Long Island lies in the Wallabi Group of the Houtman Abrolhos and is roughly 11 ha in extent with a maximum elevation of 2 m. It is part of the Long Island chain in the centre of the Wallabi Group and is a composite island consisting of unconsolidated coral rubble and some smaller areas of sand. The vegetation and relationship to other islands has been well documented by Harvey et al. (2001). The reptiles of Houtman Abrolhos were first documented by Alexander (1922) and subsequently by numerous surveys of the islands by Storr and the Aquinas College, Perth, which were summarized and re-evaluated by Storr et al. (1983). More recently there has been extensive research on the reptiles of the Wallabi Islands and opportunistic examination of several islands in the Pelsaert Group that has been summarized by How et al. (2004). The Abrolhos islands are the type locality of six reptile taxa, Pogona minor minima, Heteronotia binoei, Christinus marmoratus, Strophurus spinigerus, Egernia stokesii stokesii and Eremiascincus richardsonii. This report examines the herpetofauna of Long Island, the site for a new nature-based resort development. Methods A search for herpetofauna on Long Island was undertaken on the 8th of November 2005, by four expert herpetologists.

However, carbonate minerals (aragonite and calcite) from marine invertebrates dominate dunes on many tropical and subtropical islands. The Channel Islands of California are the northernmost localities in North America where carbonate-rich coastal dunes occur. Unlike the mainland, a lack of major river inputs of silicates to the island shelves and beaches keeps the carbonate mineral content high. The resulting distinctive white dunes are extensive on San Miguel, Santa Rosa, San Nicolas, and San Clemente islands. Beaches have limited extent on all four of these islands at present, and some dunes abut rocky shores with no sand sources at all. Thus, the origin of many of the dunes is related to the lowering of sea level to ~120 m below present during the last glacial period (~25,000 to 10,000 years ago), when broad insular shelves were subaerially exposed.

The Houtman Abrolhos reefs, situated on the western continental margin of Australia, occupy a transitional position between cool-water shelf carbonate sediments to the south and more tropical environments to the north. Their existence at the outer limits of the geographical range for coral reef growth is a result of the warm, poleward-flowing Leeuwin Current. Though the modern reefs differ ecologically from tropical reefs, their geological characteristics have been little known until recently.
