There is usually a degree of vertical stratification in the groundwater quality within the aquifers and results presented represent a composite value of salinity from drill holes at a particular time. Natural groundwater quality is influenced by annual rainfall and the evaporation (e.g. high rainfall, low evaporation areas tend to have better quality groundwater then low rainfall, high evaporation areas), the composition of the rock types through which the groundwater passes and is stored in and by physical properties of the rocks such as permeability and porosity.

Paragon Resources: Annual Report, El18/2010, Elliott Bay
PARAGON RESOURCES: ANNUAL REPORT, EL18/2010, ELLIOTT BAY To Year 4 (Nov 2013 - Nov 2014) Rodrick Campbell, BSc. and Dr Alistair Reed, BSc, PhD, MAIG. Prepared by Rockwise Pty Ltd for Paragon Resources. Wednesday, 24 November 2014 Squirrel B3 used for mobilising the helicopter portable drill rig. Paragon Resources Pty Ltd Annual Report EL18/2010 Elliott Bay Abstract This fourth Annual report for EL18/2012 ('Elliott Bay', the 'licence area') presents results from around nine weeks of on- ground field work including; two diamond drill holes totalling 412m,two induced polarization (IP) lines totalling 2100m of Dipole Dipole Geophysics, Regional stream sampling and surface sampling. The Elliott Bay licence is held by Paragon Resources Pty Ltd ("Paragon"). The Elliott Bay project was managed for Paragon by SRA (Schoer Reed & Associates) until the 1st of July, from this period onward it has been managed by Rockwise Pty Ltd (“Rockwise”). Elliott Bay licence is prospective for a suite of elements, including base metals and associated elements, Au and rare earths. The principal focus of exploration for Paragon is on Au. The fourth year exploration program was the results of a highlighted Au in rock chip and pan concentrates collected over a strike length of about 6km in the vicinity of a recently discovered fault or high strain zone referred to by Paragon as the Discovery Creek Shear Zone ('DCSZ'). An evolved understanding of the system has led to the discovery of a large NW structure that will be the focus of new programs. Other work at Elliott Bay over the year also includes desktop study and reviews of new hi-logger information, digitizing historical surface data and remodeling of historical geophysics. -
CHANGES in SOUTHWESTERN TASMANIAN FIRE REGIMES SINCE the EARLY 1800S
Papers and Proceedings o/the Royal Society o/Tasmania, Volume 132, 1998 IS CHANGES IN SOUTHWESTERN TASMANIAN FIRE REGIMES SINCE THE EARLY 1800s by Jon B. Marsden-Smedley (with five tables and one text-figure) MARSDEN-SMEDLEY, ].B., 1998 (31:xii): Changes in southwestern Tasmanian fire regimes since the early 1800s. Pap.Proc. R. Soc. Tasm. 132: 15-29. ISSN 0040-4703. School of Geography and Environmental Studies, University of Tasmania, GPO Box 252-78, Hobart, Tasmania, Australia 7001. There have been major changes in the fire regime of southwestern Tasmania over the past 170 years. The fire regime has changed from an Aboriginal fire regime of frequent low-intensity fires in buttongrass moorland (mostly in spring and autumn) with only the occasional high-intensity forest fire, to the early European fire regime of frequent high-intensity fires in all vegetation types, to a regime of low to medium intensity buttongrass moorland fires and finally to the current regime of few fires. These changes in the fire regime resulted in major impacts to the region's fire-sensitive vegetation types during the early European period, while the current low fire frequency across much of southwestern Tasmania has resulted in a large proportion of the region's fire-adapted buttongrass moorland being classified as old-growth. These extensive areas of old-growth buttongrass moorland mean that the potential for another large-scale ecologically damaging wildfire is high and, to avoid this, it would be better to re-introduce a regime oflow-intensity fires into the region. Key Words: fire regimes, fire management, southwestern Tasmania, Aboriginal fire, history. -

TWWHA Walking Track Management Strategy 1994 Vol 1
Walking Track Management Strategy for the Tasmanian Wilderness World Heritage Area Volume I Main Report January 1994 1 Summary The Walking Track Management Strategy is a strategy developed by the Tasmanian Parks & Wildlife Service for the management of walking tracks and walkers in and adjacent to the Tasmanian Wilderness World Heritage Area (WHA), in accordance with the recommendations of the World Heritage Area Management Plan. Key management issues in the region include the extensive deterioration of existing walking tracks and the unplanned development of new walking tracks in many areas. Campsite impacts, crowding, pollution and broadscale trampling damage to vegetation and soils are also creating serious problems in some areas. The Strategy has been prepared on the basis of an extensive literature survey and an inventory of tracks and track conditions throughout the WHA. Research has also been undertaken to assess usage levels, usage trends and user attitudes and characteristics throughout the WHA. The three-volume document includes: • a summary of the findings of the literature survey (section 2 and appendix B); • a description of the method used to compile the inventory of tracks and track conditions, and a summary of the findings of the inventory (section 3); • a summary of available information on usage levels, usage trends, user characteristics and attitudes and social impacts throughout the WHA (section 4 and appendix C); • an assessment of the opportunity spectrum for bushwalking in and adjacent to the WHA (section 5 and appendix -

Regional Classification of Tasmanian Coastal Waters
REGIONAL CLASSIFICATION OF TASMANIAN COASTAL WATERS AND PRELIMINARY IDENTIFICATION OF REPRESENTATIVE MARINE PROTECTED AREA SITES G.J. Edgar, J. Moverley, D. Peters and C. Reed Ocean Rescue 2000 - Marine Protected Area Program 1993/94 Project No. D705 Report to: Australian Nature Conservation Authority From: Parks and Wildlife Service, Department of Environment & Land Management 134 Macquarie St, Hobart, Tasmania 1 EXECUTIVE SUMMARY Analysis of the distribution of reef plants and animals at over 150 sites around the Tasmanian coastline and Bass Strait islands indicated that Bass Strait reef communities were distinctly different from those occurring further south. This major division in reef ecosystems reflected a boundary near Cape Grim and Little Musselroe Bay between two biogeographical provinces. Each of the two bioprovinces was divisible into four biogeographical regions (bioregions), which occurred along the northern Tasmanian coast and at the Kent Group, Furneaux Group and King Island in Bass Strait, and along the northeastern, southeastern, southern and western coasts of Tasmania. In contrast to these patterns identified using data on coastal reef communities, regional classifications for estuarine and soft-sediment faunas (based on the distribution of beach-washed shells and beach-seined fishes) were less clearly defined. In order to manage and protect Tasmanian inshore plants and animals in accordance with the principle of ecologically sustainable development, an integrated system of representative marine protected areas is considered -
