Biodiversity Management Plan Chris Buscall Environmental Compliance Lead Snowy 2.0 Project Via email: [email protected] 15/10/2020 Dear Chris Snowy 2.0 Main Works (SSI 9687) & Snowy 2.0 Exploratory Works (SSI 9208) Biodiversity Management Plan I refer to the Biodiversity Management Plan which was submitted in accordance with condition 18 of Schedule 3 of the Infrastructure Approval for the Snowy 2.0 Main Works (SSI 9687) and condition 6 of Schedule 3 of the Infrastructure Approval for the Snowy 2.0 Exploratory Works (SSI 9208). The Department has carefully reviewed the document and notes that it supersedes the approved Biodiversity Management Plan for the Snowy 2.0 Exploratory Works (SSI 9208) and is satisfied that it is prepared in accordance with the conditions. Accordingly, the Planning Secretary has approved the Biodiversity Management Plan (Revision I, dated 12 October 2020). Please ensure that the approved plan is placed on the project website at the earliest convenience. If you wish to discuss the matter further, please contact Anthony Ko on 8217 2022.

A synoptic climatology of daily precipitation that triggers a quantifiable increase in streamflow in the headwater catchments of the Snowy Mountains region is presented for the period 1958–2012. Here, previous synoptic-meteorological studies of the region are extended by using a longer-term, year-round precipitation and reanalysis dataset combined with a novel, automated synoptic-classification technique. A three-dimensional representation of synoptic circulation is developed by effectively combining meteorological variables through the depth of the troposphere. Eleven distinct synoptic types are identified, describing key circulation features and moisture pathways that deliver precipitation to the Snowy Mountains. Synoptic types with the highest precipitation totals are commonly associated with moisture pathways originating from the northeast and northwest of Australia. These systems generate the greatest precipitation totals across the westerly and high-elevation areas of the Snowy Mountains, but precipitation is reduced in the eastern-elevation areas in the lee of the mountain ranges.

Hello members and friends, Yet again we have enjoyed a very successful year. Although the Society has been running for over 30 years, our membership has remained stable and has even increased slightly in recent years, reflecting a continuing enthusiasm for and appreciation of the earth sciences and related activities. A background in geology is not a prerequisite to membership and every member is strongly encouraged to take part regardless of their level of knowledge. Although the initial aim of the Society was the exploration and understanding of Hunter Valley geolo- gy, for several years now we have continued to widen our coverage well beyond the confines of the Valley. Even so, while the organizing committee tries to include new activities into the program each year, this is becoming more difficult. But new members bring new ideas and new experiences which everyone can benefit from. Occasionally old sites are revisited, either for the benefit of new members or where the availability of new information has allowed a greater understanding of earth history. Our first extended excursion was organized (with some trepidation) into the Flinders Ranges in 1995, but this was so successful that similar trips have since taken place annually.

  • The Mosses of the Yarrangobilly Caves District, New South Wales, Australia a Review of the Mosses Collected by the Reverend W W Watts in 1906
    J. Hattori Bot. Lab. No. 82: 105- 121(July 1997) THE MOSSES OF THE YARRANGOBILLY CAVES DISTRICT, NEW SOUTH WALES, AUSTRALIA A REVIEW OF THE MOSSES COLLECTED BY THE REVEREND W W WATTS IN 1906 1 1 ALISON J. DOWNINa1, PATRICIA M. SELKIRK AND RONALD J. 0LDFIELD ABSTRACT. In 1906, Reverend W. W. Watts collected mosses in the vicinity of Yarrangobilly Caves, a limestone area in the Southern Alps of New South Wales and in 1912, with Brotherus, published a list of these species. This study updates the taxa recorded by Brotherus and Watts and compares the species collected by Watts in 1906 with our own recent (1993) collections. Most of the mosses collected by Watts are still present in the area. The few species no longer found in the immediate vicinity of Yarrangobilly are known from other locations in the Southern Alps of eastern Australia. Certain bryophyte taxa were not collected by Watts in 1906 but are now conspicuous components of the bryofiora at Yarrangobilly. Changes to the moss assemblage at Yarrangobilly are attributed to a range of environmental changes resulting from European settlement and development. KEYWORDS. Australia, bryophytes, calcareous substrates, limestone, mosses, Watts, Yarrangobilly. INTRODUCTION In the northern hemisphere it has been possible to document changes in bryophyte as­ semblages at particular locations by comparisons of studies at various times (e.g. Jones 1991 ; Bates 1995). This has not been the case in Australia, where, until recently, there have been few published species lists. In January, 1906, Reverend W. Walter Watts collected mosses at Yarrangobilly Caves in the Southern Alps of New South Wales.

    19 Murrumbidgee River Catchment Sydney Morning Herald, 10 March 1915 True Tales of the Trout Cod: River Histories of the Murray-Darling Basin 19-1 STOCKING THE BARREN JACK DAMS TO THE EDITOR OF THE HERALD Sir, - A short time since a paragraph appeared in the “Herald” re stocking the dams at Barren Jack with economic fish, i.e. cod, perch etc. A request was sent to the Fishery Department to take the matter in hand, and an expert was detailed to carry out the suggestion. This expert’s idea was to capture fish in the reaches of the Lower Murrumbidgee, and transplant them to the said dam. Instead of so doing it will be far better to permit the dams to be stocked by or with the fish that are in thousands above the dam. They are precisely of the same species as will be obtained from the stretches of the same river lower down. The young fish that are in the waters above the dams will be sure to make for the deeper waters: it is their natural habitat – the larger and deeper the waterholes in rivers the larger its fish inhabitants. The writer has seen young perch and cod-fish in the Murrumbidgee and its tributaries near Cooma by the thousand. Then why take the trouble and go to the expense to take fish from one part of the river, and dump them down among the same species in another part of the same river? “Coals to Newcastle” again. The great flood that occurred two or three months ago in the upper parts of the Murrumbidgee gave ample proof that the codfish etc.

  • Protecting the Natural Treasures of the Australian Alps
    Protecting the Natural Treasures of the Australian Alps Alpine National Park Avon Wilderness Park Bimberi Nature Reserve Brindabella National Park Kosciuszko National Park Mount Buffalo National Park Namadgi National Park Scabby Range Nature Reserve Snowy River National Park Peter Coyne May 2001 A report to the Natural Heritage Working Group of the Australian Alps Liaison Committee Protecting the Natural Treasures of the Australian Alps About the author Peter Coyne has had an interest in the Australian Alps from early childhood and a long history of interest and involvement in protected area issues. This began with preparation of a management plan as an honours project when such a document was a real novelty. He had the rare opportunity to create national parks, working with the Land Conservation Council in Victoria where he defined the boundaries and gave names to proposed new national parks, including Croajingalong, Snowy River and Tingaringy, which the Government adopted. Dr Coyne joined the Australian National Parks and Wildlife Service in its early days and spent four years establishing the Service’s office and operations on Norfolk Island, and introducing the concept of environmental management to the island’s community and government (which led to the creation of the Norfolk Island National Park). He then headed the ANPWS Park Planning Section, personally preparing the management plan for Kakadu National Park and having responsibility for preparation of other plans ranging from central Australia (Uluru–Kata Tjuta) to marine national nature reserves in the Coral and Timor Seas, and park plans for Australia’s remote Indian Ocean Territories. During this time he also developed the legislation and lease to enable transfer of Uluru to its traditional Aboriginal owners and its lease back to the Director of National Parks and Wildlife for continuing use as a national park.
