Alought the percentage may seem small as an average (Approx. 17% per annum) large flows have at times contributed markedly in times when the Lower Murray River had periods of low or no flow. This was especially evident during the Millennium Drought when a large flow was shepherded through to the Lower Lakes and Coorong thereby averting what would have been a natural disaster and the possibility of Adelaide running out of water.

  • An Ecological History of the Koala Phascolarctos Cinereus in Coffs Harbour and Its Environs, on the Mid-North Coast of New South Wales, C1861-2000
    An Ecological History of the Koala Phascolarctos cinereus in Coffs Harbour and its Environs, on the Mid-north Coast of New South Wales, c1861-2000 DANIEL LUNNEY1, ANTARES WELLS2 AND INDRIE MILLER2 1Offi ce of Environment and Heritage NSW, PO Box 1967, Hurstville NSW 2220, and School of Biological Sciences, University of Sydney, NSW 2006 ([email protected]) 2Offi ce of Environment and Heritage NSW, PO Box 1967, Hurstville NSW 2220 Published on 8 January 2016 at http://escholarship.library.usyd.edu.au/journals/index.php/LIN Lunney, D., Wells, A. and Miller, I. (2016). An ecological history of the Koala Phascolarctos cinereus in Coffs Harbour and its environs, on the mid-north coast of New South Wales, c1861-2000. Proceedings of the Linnean Society of New South Wales 138, 1-48. This paper focuses on changes to the Koala population of the Coffs Harbour Local Government Area, on the mid-north coast of New South Wales, from European settlement to 2000. The primary method used was media analysis, complemented by local histories, reports and annual reviews of fur/skin brokers, historical photographs, and oral histories. Cedar-cutters worked their way up the Orara River in the 1870s, paving the way for selection, and the fi rst wave of European settlers arrived in the early 1880s. Much of the initial development arose from logging. The trade in marsupial skins and furs did not constitute a signifi cant threat to the Koala population of Coffs Harbour in the late nineteenth and early twentieth centuries. The extent of the vegetation clearing by the early 1900s is apparent in photographs.
