Turquoise Coast Island Nature Reserves PREFACE All national parks, conservation parks and nature reserves in Western Australia are vested in the Conservation Commission of Western Australia (Conservation Commission) and are managed on its behalf by the Department of Conservation and Land Management (CALM). CALM prepares management plans on behalf of the Conservation Commission which issues draft plans for public comment and provides final plans for approval by the Minister for the Environment. The Conservation and Land Management Act 1984 (CALM Act) specifies that management plans must contain: v a statement of the policies or guidelines proposed to be followed; and v a summary of operations proposed to be undertaken. In accordance with Section 55 of the CALM Act, the term of this plan will be ten years, or until such time that the plan is superseded by a new management plan. This management plan is for the 13 island nature reserves which represent a chain of approximately 40 islands off the Western Australian coast between Lancelin and Dongara. One island (Target Rock) is proposed for inclusion in the nature reserves. The reference to ‘the islands’ in this management plan refers to both the existing and proposed island nature reserves. This management plan should be viewed in conjunction with the management plan for the Jurien Bay Marine Park in which many of the islands lie. The planning process for both the islands and marine park was undertaken concurrently, and their management will be integrated and implemented together. i ACKNOWLEDGMENTS This Turquoise Coast Island Nature Reserves Management Plan was prepared by Liesl Jonker (CALM’s Marine Conservation Branch) and Laurina Bullen (CALM’s Management Planning Unit). Many people provided valuable assistance in the preparation of this plan, including: v staff from CALM’s Midwest Region and Moora District, in particular Sue Hancock, Keith Hockey, Andrew Darbyshire, Peter Fishwick, Nigel Sercombe, Kelly Gillen, Anthony Desmond and David Rose (former District Manager, Moora); v staff from CALM’s Science Division; v staff from CALM’s Information Management Branch; and v Friends of Lancelin Island. NOMENCLATURE Inclusion of a name in this publication does not imply its approval by the relevant nomenclature authority. The word ‘Noongar’ can be spelt in numerous ways. The spelling of Noongar in this form should also be seen to encompass all other spellings. ii Table 1.

  • Characterizing the Hydrodynamics of Jurien Bay, Western Australia
    Characterizing the Hydrodynamics of Jurien Bay, Western Australia Kellie Holloway June 2006 Professor Charitha Pattiaratchi ------------------------------------------------------------------------------------- This dissertation is submitted in partial fulfillment of the requirements for the Bachelor of Engineering (Applied Ocean Science) ------------------------------------------------------------------------------------- Abstract Abstract Jurien Bay is a small town on the Central West Coast of Western Australia. With an expanding economy based on fishing, aquaculture and tourism and proximity to Perth, Jurien Bay is expected to grow rapidly over the coming years. Increasing anthropogenic pressure has the potential to compromise the currently pristine natural environment. The livelihood of the town and the economy relies on the quality of the marine environment in particular; hence it is important to understand the dynamics of the system. This study investigates the characteristics of circulation in Essex Lagoon, a deep basin to the south of the main Jurien Bay settlement. This area is a particularly important for investigation due to the future impact of the adjacent Ardross Estates development and the aquaculture zone located within Essex Lagoon. An Acoustic Doppler Current Profiler (ADCP) was deployed in summer 2006 to obtain profiles of current velocity and magnitude over three weeks in Essex Lagoon. This data complemented similar data collected during winter 2002 in Essex Lagoon and was used to carry out a seasonal comparison of currents, to characterize circulation patterns and to examine the potential for outside forcing such as atmospheric pressure systems and the Leeuwin Current to influence circulation. A distinct seasonality was found in the circulation characteristics between summer and winter and this was primarily influenced by seasonality in the wind field.

  • VIII-17 West-Central Australian Shelf: LME #44
    VIII East Asian Seas 321 VIII-17 West-Central Australian Shelf: LME #44 T. Irvine, J. Keesing, N. D’Adamo, M.C. Aquarone and S. Adams The West-Central Australian Shelf LME extends off Western Australia (WA) from Cape Leeuwin (~34.5°S) to Northwest Cape (~22°S). This LME owes much of its biogeographic unity to the respective connecting influences of the West Australian Current, a northward flow coming from the circulation pattern of the counterclockwise Indian Ocean gyre, and the Leeuwin Current (LC), the only west coast poleward-flowing eastern boundary current in the southern hemisphere. The LC is a major southward flow of warm, low nutrient, buoyant tropical water along this LME’s relatively narrow continental shelf, and is responsible for tropical reefs and associated marine flora and fauna flourishing further south than anywhere else in the world (CALM, 1994). In addition to these regional scale currents, there are wind-driven coastal counter currents dominating the circulation close to shore mainly during the austral spring/summer period (Pattiaratchi, 2006). Relatively high energy from sea and swell is a major feature of this LME, but there are embayments and lagoons where waves are restricted or effectively blocked, with sheltered highly biodiverse protected habitats occurring behind offshore limestone reefs in many localities (CALM, 1994). The LME has an extremely narrow shelf, in some areas being merely 40 km wide, and covers an area of nearly 550,000 km2, about 2% of which is gazetted as a marine protected area (MPA) that contains 0.37% of the world’s coral reefs (CALM, 2005a; Sea Around Us, 2007; www.dec.wa.gov.au).

  • Overview of Tasmania's Offshore Islands and Their Role in Nature

Bryant and Stephen Harris (with one text-figure, two tables, eight plates and two appendices) Bryant, S.L. & Harris, S. 2020 (9:xii): Overview of Tasmania’s offshore islands and their role in nature conservation.Papers and Proceedings of the Royal Society of Tasmania 154: 83–106. https://doi.org/10.26749/rstpp.154.83 ISSN: 0080–4703. Tasmanian Land Conservancy, PO Box 2112, Lower Sandy Bay, Tasmania 7005, Australia (SLB*); Department of Archaeology and Natural History, College of Asia and the Pacific, Australian National University, Canberra, ACT 2601 (SH). *Author for correspondence: Email: [email protected] Since the 1970s, knowledge of Tasmania’s offshore islands has expanded greatly due to an increase in systematic and regional surveys, the continuation of several long-term monitoring programs and the improved delivery of pest management and translocation programs. However, many islands remain data-poor especially for invertebrate fauna, and non-vascular flora, and information sources are dispersed across numerous platforms. While more than 90% of Tasmania’s offshore islands are statutory reserves, many are impacted by a range of disturbances, particularly invasive species with no decision-making framework in place to prioritise their management. This paper synthesises the significant contribution offshore islands make to Tasmania’s land-based natural assets and identifies gaps and deficiencies hampering their protection. A continuing focus on detailed gap-filling surveys aided by partnership restoration programs and collaborative national forums must be strengthened if we are to capitalise on the conservation benefits islands provide in the face of rapidly changing environmental conditions and pressure for future use.

KAY & J. SCOTT KEOGH 1 Division of Evolution, Ecology and Genetics, Research School of Biology, The Australian National University, Canberra, ACT 0200, Australia 1 Corresponding author. E-mail: [email protected] Abstract Ctenotus is the largest and most diverse genus of skinks in Australia with at least 97 described species. We generated large mitochondrial and nuclear DNA data sets for 70 individuals representing all available species in the C. labillardieri species- group to produce the first comprehensive phylogeny for this clade. The widespread C. labillardieri was sampled extensively to provide the first detailed phylogeographic data set for a reptile in the southwestern Australian biodiversity hotspot. We supplemented our molecular data with a comprehensive morphological dataset for the entire group, and together these data are used to revise the group and describe a new species. The morphologically highly variable species C. labillardieri comprises seven well-supported genetic clades that each occupy distinct geographic regions. The phylogeographic patterns observed in this taxon are consistent with studies of frogs, plants and invertebrates, adding strength to emerging biogeographic hypotheses in this iconic region. The species C. catenifer, C. youngsoni, and C. gemmula are well supported, and despite limited sampling both C. catenifer and C. gemmula show substantial genetic structure.
