Corangamite Heritage Study Stage 2 Volume 3 Reviewed
CORANGAMITE HERITAGE STUDY STAGE 2 VOLUME 3 REVIEWED AND REVISED THEMATIC ENVIRONMENTAL HISTORY Prepared for Corangamite Shire Council Samantha Westbrooke Ray Tonkin 13 Richards Street 179 Spensley St Coburg 3058 Clifton Hill 3068 ph 03 9354 3451 ph 03 9029 3687 mob 0417 537 413 mob 0408 313 721 [email protected] [email protected] INTRODUCTION This report comprises Volume 3 of the Corangamite Heritage Study (Stage 2) 2013 (the Study). The purpose of the Study is to complete the identification, assessment and documentation of places of post-contact cultural significance within Corangamite Shire, excluding the town of Camperdown (the study area) and to make recommendations for their future conservation. This volume contains the Reviewed and Revised Thematic Environmental History. It should be read in conjunction with Volumes 1 & 2 of the Study, which contain the following: • Volume 1. Overview, Methodology & Recommendations • Volume 2. Citations for Precincts, Individual Places and Cultural Landscapes This document was reviewed and revised by Ray Tonkin and Samantha Westbrooke in July 2013 as part of the completion of the Corangamite Heritage Study, Stage 2. This was a task required by the brief for the Stage 2 study and was designed to ensure that the findings of the Stage 2 study were incorporated into the final version of the Thematic Environmental History. The revision largely amounts to the addition of material to supplement certain themes and the addition of further examples of places that illustrate those themes. There has also been a significant re-formatting of the document. Most of the original version was presented in a landscape format. -
SOUTH WEST VICTORIA LANDSCAPE ASSESSMENT STUDY Regional Overview Report: Executive Summary
SOUTH WEST VICTORIA LANDSCAPE ASSESSMENT STUDY Regional Overview Report: Executive Summary June 2013 FOREWORD FOREWORD The landscapes of South West Victoria tell the story of a rich and complex evolution - reflective of the region’s geological morphology, economy, ecology and cultural history. They include the rugged and spectacular Grampians Ranges (Gariwerd); the cones and lakes of the volcanic plains; and the majestic River Red Gums scattered throughout the pastoral lands. The purpose of this landscape assessment is to examine the character and significance of the landscapes of South West Victoria; to understand how they may be affected by future change; and to protect and manage those values that are most important, for future generations. © 2013 DPCD South West Victoria Landscape Assessment Study | REGIONAL OVERVIEW REPORT 3 Logo is at twice the size for the footer ACKNOWLEDGEMENTS Traditional Owners Project Team The Study acknowledges that the State of Victoria has an ancient and proud Aboriginal history and complex John Phillips (Project Department of Planning and Jacinta Rivette / Jessica City of Greater Geelong ownership and land stewardship systems stretching back Director) Community Development Hurse many thousands of years.

Some Observations on the Formation, Structure and Morphology of Halloysite
Clay Minerals, (2016) 51, 395–416 Unique but diverse: some observations on the formation, structure and morphology of halloysite G. JOCK CHURCHMAN1,*, P.PASBAKHSH2 ,D.J.LOWE3 AND B.K.G. THENG4 1 School of Agriculture, Food and Wine, University of Adelaide, Adelaide 5005, Australia 2 School of Engineering, Monash University Malaysia, Bandar Sunway, 47500, Selangor, Malaysia 3 School of Science, Faculty of Science and Engineering, University of Waikato, Hamilton 3240, New Zealand 4 Landcare Research, Palmerston North 4442, New Zealand (Received 04 November 2015; revised 11 June 2016; Associate Editor: Steve Hillier) ABSTRACT: New insights from the recent literature are summarized and new data presented concerning the formation, structure and morphology of halloysite. Halloysite formation by weathering always requires the presence of water. Where substantial drying occurs, kaolinite is formed instead. Halloysite formation is favoured by a low pH. The octahedral sheet is positively charged at pH < ∼8, whereas the tetrahedral sheet is negatively charged at pH > ∼2. The opposing sheet charge would facilitate interlayer uptake of H2O molecules. When halloysite intercalates certain polar organic molecules, additional (hkl) reflections appear in the X-ray diffraction pattern, suggesting layer re-arrangement which, however, is dissimilar to that in kaolinite. Associated oxides and oxyhydroxides of Fe and Mn may limit the growth of halloysite particles as does incorporation of Fe into the structure. Particles of different shape and Fe content may occur within a given sample of halloysite. KEYWORDS: water, pH, iron, particle size, morphology, organic complexes, 2-layer structure. Since halloysite was first described by Berthier (1826), shapes, including spheroidal, platy and prismatic, in the clay mineral has attracted a great deal of attention addition to being fibrous or tubular (Joussein et al., and interest. -

A Review of Historic Western Victorian Lake Conditions in Relation to Fish Deaths
A REVIEW OF HISTORIC WESTERN VICTORIAN LAKE CONDITIONS IN RELATION TO FISH DEATHS Publication 1108 March 2007 EXECUTIVE SUMMARY Eel deaths occurred in waterways across Victoria from 2004 to 2006. EPA Victoria worked with responsible agencies to investigate the cause of the deaths. An information gap was identified regarding changes throughout the catchments over time. Much of this knowledge had not been documented formally and was difficult to assess. It is important to note that this report is based on a number of published accounts of the historical timeline as well as utilising personal accounts of history. Therefore there may be small discrepancies in exact dates. Anecdotal evidence and unpublished reports of the history of lakes Modewarre, Bolac and Colac indicate that, over the past 150 years, all lakes in the Western District have shown a distinct pattern of drying out during periods of extended drought. As early as 1846 the lakes showed signs of drying, which would indicate that any fish within those lakes also died due to lack of good quality water. The three lakes examined have been stocked by landholders, recreational anglers or commercial eel fishermen to hold the current stock of fish and eels. The catchments in which each lake sits have undergone changes, including culverts being developed to reduce flooding, the size of water storage reservoirs being increased and changes in agricultural practices. ACKNOWLEDGEMENTS EPA would like to formally acknowledge the contribution of all those who assisted with the research into the Western District lakes. Much information was held in the minds of those who visit the lakes regularly for recreation, farming and lifestyle, and it is this that has provided such broad insight into one of Victoria’s precious resources. -
