BirdLife Australia is an independent science-based conservation organisation with more than 13,000 members and 100,000 supporters throughout Australia. We have an extensive ongoing program of bird conservation research and a range of citizen science projects that engage thousands of Australians. Our primary objective is to conserve and protect Australia's native birds and their habitat. We have an extensive ongoing program of bird conservation research, including our Shorebirds 2020 program, developed to address the ongoing decline of Australia’s resident and migratory shorebirds. Our Special Interest Group, the Australasian Wader Studies Group (AWSG) conducts and promotes shorebird research and conservation throughout Australasia. Through our Shorebirds 2020 program and the work of the AWSG, BirdLife Australia is recognised as a leading authority on the ecology and conservation of Australia’s shorebirds. BirdLife Australia has established a regular monitoring program for important shorebird sites throughout Australia including the Port Phillip Bay (Western Shoreline) and Bellarine Peninsula, and Western Port Ramsar sites. Both sites are recognised as providing internationally important habitat for waterbirds including a large number of migratory and threatened species listed under the Commonwealth Environment Protection & Biodiversity Conservation Act 1999 (EPBC Act). BirdLife Australia has a long history of involvement in recovery actions for the Critically Endangered Orange-bellied Parrot, including ongoing coordination of the mainland monitoring program for the species. As Australia’s leading bird conservation advocate, BirdLife Australia should be considered a key stakeholder in future planning for the location of Victoria’s second container port.

Initially it was found only in Corio Bay, but during the past fiveyears it has spread so that it now occurs throughout the western half of Port Phillip Bay. • Densities of Sabella in many parts of the bay remain low but densities are usually higher (up to 13/m2 ) in deeper water and they extend into shallower depths in calmer regions. • Sabella larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor in soft sediment . • Changes to fish communities following the establishment of Sabella were analysed using multidimensional scaling and BACI (Before, After, Control, Impact) design analyses of variance.

  • Climatic and Oceanographic Effects on Survival of Little Penguins in Southeastern Australia
    SCIENTIA MANU E T MENTE CLIMATIC AND OCEANOGRAPHIC EFFECTS ON SURVIVAL OF LITTLE PENGUINS IN SOUTHEASTERN AUSTRALIA A thesis submitted for the degree of Doctor of Philosophy By Lucia-Marie Ganendran Applied and Industrial Mathematics Research Group, School of Physical, Environmental and Mathematical Sciences, The University of New South Wales, Australian Defence Force Academy. December 2017 PLEASE TYPE THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: Ganendran First name: Lucia-Marie Other name/s: Billie Abbreviation for degree as given in the University calendar: PhD School: School of Physical, Environmental and Mathematical Faculty: UNSW Canberra Sciences Title: Climatic and Oceanographic Effects on Survival of Little Penguins in Southeastern Australia Abstract 350 words maximum: (PLEASE TYPE) Climate change can impact on the survival of seabirds. While many studies have investigated the influences of climatic and oceanographic variables on seabird breeding, fewer have been able to capture the processes affecting survival. In this study, I carried out a mark-recapture analysis on a 46-year penguin dataset to study the effects of some climatic and oceanographic variables on the survival of little penguins Eudyptula minor in southeastern Australia. A priori knowledge of the birds' annual cycle and patterns of movement informed my selection of meaningful and biologically sensible variables. Two age classes of penguins were considered, based on their differing patterns of movement: first-year birds and adult birds in their second and subsequent years of life. The climatic and oceanographic variables considered in this study were wind strength, sea-surface temperature, east-west sea temperature gradient, air temperature, rainfall, humidity and chlorophyll a concentration.

    . https://doi.org/10.24199/j.mmv.1979.40.04 31 July 1979 VERTEBRATE FAUNA OF SOUTH GIPPSLAND, VICTORIA By K. C. Norris, A. M. Gilmore and P. W. Menkhorst Fisheries and Wildlife Division, Ministry for Conservation, Arthur Ryiah Institute for Environmental Research, 123 Brown Street, Heidelberg, Victoria 3084 Abstract The South Gippsland area of eastern Victoria is the most southerly part of the Australian mainland and is contained within the Bassian zoogeographic subregion. The survey area contains most Bassian environments, including ranges, river flats, swamps, coastal plains, mountainous promontories and continental islands. The area was settled in the mid 180()s and much of the native vegetation was cleared for farming. The status (both present and historical) of 375 vertebrate taxa, 50 mammals, 285 birds, 25 reptiles and 15 amphibians is discussed in terms of distribution, habitat and abundance. As a result of European settlement, 4 mammal species are now extinct and several bird species are extinct or rare. Wildlife populations in the area now appear relatively stable and are catered for by six National Parks and Wildlife Reserves. Introduction TOPOGRAPHY AND PHYSIOGRAPHY {see Hills 1967; and Central Planning Authority 1968) Surveys of wildlife are being conducted by The north and central portions of the area the Fisheries and Wildlife Division of the are dominated by the South Gippsland High- Ministry for Conservation as part of the Land lands (Strzelecki Range) which is an eroded, Conservation Council's review of the use of rounded range of uplifted Mesozoic sand- Crown Land in Victoria. stones and mudstones rising to 730 m.
