There is a quite strenuous walk along the Tarn Shelf, over Newdegate Pass & back along the Rodway Range. Students that are not physically fit must seek the advice of the unit coordinator. This part of the course is based at the Giant’s Table, Maydena. The second part of the course introduces demographic techniques, conservation strategies & practice, & examines applied ecological practice in forestry harvesting methods in wet sclerophyll forest in the long-term monitoring site at Warra as day excursions from the Sandy Bay campus. Assessment is by: a field test (50%) on the last day of the course, assessing plant identification ability & an understanding of the ecological processes shaping the vegetation; two reports based on data collected in the field (40%); & a group plant collection (10%). Transport Transport to Mt Field from the University is provided. Vehicles will depart from the Life Sciences car park at 9:00 am Mon. 8th Feb. & return at 5:00 pm on Fri. 12th Feb. Please bring your lunch, waterproofs & collecting gear packed separately for Day 1. Equipment 1. Adequate clothing is essential; warm clothes, good boots & waterproof clothing are required for protection against rain, wind & snow. The weather at Mt Field can be very changeable & work will proceed regardless of weather. Swimming is possible in good weather, so bring bathers. Also bring spare footwear & clothing for evening wear. Bring a light daypack for day trips 2. You will be working at 1000 metres, so bring a sunscreen (15 +), insect repellant & a shade hat. 3. Bring personal collecting equipment, field note books, masking tape, zip-lock plastic bags, hand lens, camera, clipboard & texts. Accommodation & Costs Accommodation is luxurious this year, but you will need to bring your own fluffy dressing gown, slippers, & towel. There is a levy of $120 to help cover accommodation costs, the School will fund the remainder. This should be paid prior to the course at the Cashiers Office (Admin. Building), quoting account no. 1.10.319.44787.3807. Alternatively, you may find your own accommodation but this would diminish the experience. If you have difficulty in paying the levy, please discuss the matter with Dr Anthony Koutoulis. Cooking Dinner is supplied on all four nights. Bring food for breakfast & lunches, although milk & bread, tea & coffee will be provided. Be prepared to take lunches & drinks into the field.

    Tasmanian Wilderness World Heritage Area

    Appendix 4 1 World Heritage Values of the Tasmanian Wilderness 1.1 Note that the Department of the Environment's website states that: A draft Statement of Outstanding Universal Value which will take into account the new areas added in 2013 is expected to be considered by the World Heritage Committee in 2014. Outstanding Universal Value 1.2 The Tasmanian Wilderness is an extensive, wild, beautiful temperate land where cultural heritage of the Tasmanian Aboriginal people is preserved. 1.3 It is one of the three largest temperate wilderness areas remaining in the Southern Hemisphere. The region is home to some of the deepest and longest caves in Australia. It is renowned for its diversity of flora, and some of the longest lived trees and tallest flowering plants in the world grow in the area. The Tasmanian Wilderness is a stronghold for several animals that are either extinct or threatened on mainland Australia. 1.4 In the southwest Aboriginal people developed a unique cultural tradition based on a specialized stone and bone toolkit that enabled the hunting and processing of a single prey species (Bennett's wallaby) that provided nearly all of their dietary protein and fat. Extensive limestone cave systems contain rock art sites that have been dated to the end of the Pleistocene period. Southwest Tasmanian Aboriginal artistic expression during the last Ice Age is only known from the dark recesses of limestone caves. 1.5 The Tasmanian Wilderness was inscribed on the World Heritage List in 1982 and extended in 1989, 2010, 2012 and again in 2013.

  • Comparative Floral Presentation and Bee-Pollination in Two Sprengelia Species (Ericaceae)

    Comparative Floral Presentation and Bee-Pollination in Two Sprengelia Species (Ericaceae)

    Comparative floral presentation and bee-pollination in two Sprengelia species (Ericaceae) Karen A. Johnson* and Peter B. McQuillan School of Geography and Environmental Studies, University of Tasmania, Private Bag 78, Hobart, Tasmania 7001, Australia. *Corresponding author. E-mail: [email protected] Abstract: Pollination by sonication is unusual in the Styphelioideae, family Ericaceae. Sprengelia incarnata and Sprengelia propinqua have floral characteristics that suggested they might be adapted to buzz pollination.Both species have florally similar nectarless flowers except that the stamens ofSprengelia propinqua spread widely after the flower opens, while those of Sprengelia incarnata cohere in the centre of the flower. To test whether sonication occurs, we observed bee behaviour at the flowers of both plant species, documented potential pollinators, and examined their floral and pollen attributes. We found that Sprengelia incarnata had smaller and drier pollen than Sprengelia propinqua. We found that Sprengelia incarnata was sonicated by native bees in the families Apidae (Exoneura), Halictidae (Lasioglossum) and Colletidae (Leioproctus, Euryglossa). Sprengelia propinqua was also visited by bees from the Apidae (Exoneura) and Halictidae (Lasioglossum), but pollen was collected by scraping. The introduced Apis mellifera (Apidae) foraged at Sprengelia propinqua but ignored Sprengelia incarnata. The two Sprengelia species shared some genera of potential pollinators, but appeared to have diverged enough in their floral and pollen characters to elicit different behaviours from the native and introduced bees.

  • Plant Life of Western Australia

    Plant Life of Western Australia

    INTRODUCTION The characteristic features of the vegetation of Australia I. General Physiography At present the animals and plants of Australia are isolated from the rest of the world, except by way of the Torres Straits to New Guinea and southeast Asia. Even here adverse climatic conditions restrict or make it impossible for migration. Over a long period this isolation has meant that even what was common to the floras of the southern Asiatic Archipelago and Australia has become restricted to small areas. This resulted in an ever increasing divergence. As a consequence, Australia is a true island continent, with its own peculiar flora and fauna. As in southern Africa, Australia is largely an extensive plateau, although at a lower elevation. As in Africa too, the plateau increases gradually in height towards the east, culminating in a high ridge from which the land then drops steeply to a narrow coastal plain crossed by short rivers. On the west coast the plateau is only 00-00 m in height but there is usually an abrupt descent to the narrow coastal region. The plateau drops towards the center, and the major rivers flow into this depression. Fed from the high eastern margin of the plateau, these rivers run through low rainfall areas to the sea. While the tropical northern region is characterized by a wet summer and dry win- ter, the actual amount of rain is determined by additional factors. On the mountainous east coast the rainfall is high, while it diminishes with surprising rapidity towards the interior. Thus in New South Wales, the yearly rainfall at the edge of the plateau and the adjacent coast often reaches over 100 cm.

  • Forests and Scrublands of Northern Fiordland

    Forests and Scrublands of Northern Fiordland

    80 Vol. 1 FORESTS AND SCRUBLANDS OF NORTHERN FIORDLAND J. WARDLE, J. HAYWARD, and J. HERBERT, Forest and Range Experiment Station, New Zealand Forest Service, Rangiora (Received for publication 18 January 1971) ABSTRACT The composition and structure of the forests and scrublands of northern Fiordland were recorded at 1,053 sample points. The vegetation at each sample point was classified into one of 16 associations using a combination of Sorensen's 'k' index of similarity, and a multi-linkage cluster analysis. The associations were related to habitat and the distribution of each was determined. The influence of the introduced ungulates, red deer and wapiti, on the forests and scrublands was determined. Stand structure was analysed to provide infor­ mation on the susceptibility of the vegetation to damage from browsing and on the history of ungulate utilisation of the vegetation. Browse indices were calculated to provide information on current ungulate utilisation of the vegetation. INTRODUCTION A reconnaissance of northern Fiordland was carried out during the summer of 1969-70 by staff of the Forest and Range Experiment Station. The purpose was to describe the composition, structure, and habitat of the forest and scrub associations, to determine both present and past influence of ungulates on them, and to establish a number of permanent reference points to permit measurement of future changes in the vegetation. The area studied lies between the western shores of Lake Te Anau and the Tasman Sea. The southern boundary is the South Fiord of Lake Te Anau, the Esk Burn and Windward River catchments, and Charles Sound; the northern boundary is the Worsley and Transit River catchments (Fig.
