Banksia Attenuata — Eucalyptus Marginata Woodlands of the Eastern Side of the Swan Coastal Plain (Floristic Community Type Banksia attenuata — Eucalyptus marginata woodlands of the eastern side of the Swan Coastal Plain (floristic community type 20b as originally described in Gibson et al. (1994)) TEC Description The community occurs on sands at the base of the scarp predominantly on the Pinjarra Plain and Ridge Hill Shelf. Most of the occurrences of this community comprise Banksia attenuata (slender banksia) - Eucalyptus marginata (jarrah) woodlands but the community also occurs as Banksia woodlands and heaths. The sedge Mesomelaena pseudostygia is a common component of the community, which is very species rich and has a diverse shrub layer and low weed frequency. Hakea stenocarpa (narrow- fruited hakea), Conostylis setosa (white cottonhead), and Johnsonia pubescens subsp. cygnorum (priority 2) generally differentiate the community from similar Banksia communities. The community is also known as “floristic community type 20b” as originally described in Gibson N., Keighery B.J., Keighery G.J., Burbidge A.H. and Lyons M.N. (1994) “A floristic survey of the southern Swan Coastal Plain” (unpublished report for the Australian Heritage Commission prepared by the Department of Conservation and Land Management and the Conservation Council of Western Australia (Inc.)). Distribution Department of Biodiversity, Conservation and Attractions (DBCA) Regions: Swan and South West DBCA Districts: Swan Coastal, Perth Hills and Wellington Local Government Authorities: Serpentine – Jarrahdale, Harvey, Murray, Armadale, Gosnells, Swan, Bullsbrook and Waroona. Habitat Requirements The community is found on a range of soils on the base of the Darling Scarp from Yarloop to Stratton. Soils are mainly yellow orange and yellow sands. The community occurs largely on Ridge Hill Shelf or Guildford clays, or at the boundary of the two units. Indigenous Interests An Aboriginal Sites Register is kept by the Department of Indigenous Affairs and lists a suite of significant sites within or in close proximity to occurrences. The South West Aboriginal Land and Sea Council (SWALSC), an umbrella group, covers the areas in which the community occurs. Traditional owner groups: Whadjuk, Pindjarup. Conservation Status Listed as endangered under WA Minister Environmentally Sensitive Areas list in policy. Threatening Processes The major threats to the community are weed invasion, dieback caused by Phytophthora species, clearing, grazing, recreational impacts, rubbish dumping, and too frequent fire. Recovery Plan An interim recovery plan has been produced for the community, and outlines the recovery actions required to reduce the threats and to maintain or improve the overall condition in the known locations. Recommended actions include monitoring the flora, developing and implementing a fire management strategy, weed control and rehabilitation, determining hydrological requirements, fencing, monitoring dieback disease, and seeking to improve tenure security.

Academic Editor: Steven Jansen Received: 7 April 2015 / Accepted: 3 June 2015 / Published: 9 June 2015 Abstract: Globally, drought and heat-induced forest disturbance is garnering increasing concern. Species from Mediterranean forests have resistance and resilience mechanisms to cope with drought and differences in these ecological strategies will profoundly influence vegetation composition in response to drought. Our aim was to contrast the early response of two co-occurring forest species, Eucalyptus marginata and Corymbia calophylla, in the Northern Jarrah Forest of southwestern Australia, following a sudden and severe drought event. Forest plots were monitored for health and response, three and 16 months following the drought. Eucalyptus marginata was more susceptible to partial and complete crown dieback compared to C. calophylla, three months after the drought. However, resprouting among trees exhibiting complete crown dieback was similar between species.

By EurekAlert! Australia's giant eucalyptus trees are the tallest flowering plants on earth, yet their unique relationship with fire makes them a puzzle for ecologists. Now the first global assessment of these giants, published in New Phytologist, seeks to end a century of debate over the species' classification and may change the way it is managed in future. Gigantic trees are rare. Of the 100,000 global tree species only 50, less than 0.005 per cent, reach over 70 metres in height. While many of the giants live in Pacific North America, Borneo and similar habitats, 13 are eucalypts endemic to Southern and Eastern Australia. The tallest flowering plant in Australia is Eucalyptus regnans, with temperate eastern Victoria and Tasmania being home to the six tallest recorded species of the genus.

  • Three Types of Fault - Teacher Notes
    Three Types of Fault - Teacher Notes Faults are breaks in rock where one side is displaced relative to the other. Fault displacements can be on any scale from millimetres to kilometres to hundreds of kilometres. Friction along fault surfaces causes strain to build up and be released as earthquakes. Stress causing fault movement is greatest along continental plate margins. The Indo-Australian plate moves northward relative to the Eurasian plate at about 10mm per year. Earthquakes are frequent and severe. Luckily Australia lies away from the margins of its plate. 1. Normal Fault - Extension of Crust Where the crust is being stretched or extended “normal” faults occur. During ancient geological times Australia, India, Africa, New Zealand and Antarctica were welded together to form the supercontinent of Gondwanaland. About 184 million years ago the supercontinent began to break up and the present continental plates started to move apart. Continental crust between the separating plates was stretched thin and was split by a series of faults. The stretched crust then sagged to create a marine sedimentary basin bounded by fault block ranges. The diagram below is a section through the Earth. WEST EAST Crust sags downward in a normal fault. An initiative supported by Woodside and ESWA Three Types of Fault - Teacher Notes This sag can be demonstrated by stretching some warm silly putty or play dough. The Darling Scarp, which runs north to south near the coast of Western, Australia is a normal fault, which has been activated and reactivated over more than a billion years. The down-faulted western side has more than 15km of sediments laid down in it and the Indian Ocean fills the sagging central portion.

  • Toward Sustainable Management: Southern Africa's Afromontane, And
    Proceedings 6th National Conference of the Australian Forest History Society Inc, Michael Calver et al. (eds) © 2005 Millpress, Rotterdam, ISBN 90 5966 026 9 Toward sustainable management: Southern Africa’s Afromontane, and Western Australia’s jarrah forests Grant Wardell-Johnson Natural and Rural Systems Management, The University of Queensland, Gatton, 4343 Michael Calver Biological Sciences, Murdoch University, Murdoch, Western Australia 6150 Peer reviewed contribution Keywords: logging, Afromontane forest, jarrah forest, management regimes, sustainability, silviculture, employment, plantations ABSTRACT: We review the history of forest management in two southern hemisphere forest types: Western Australia’s jarrah Eucalyptus marginata forests and the Afromontane forests of southern Africa to determine approaches for achieving sustainable forest management. We argue that despite major differences in the ecology and biogeography of these two forest types, a shared pattern in the history of exploitation may provide lessons for achieving sustainable management across forest types. While advanced silvicultural understanding has long been achieved in both for- est types, this in itself has not led to either sustainable management or to public acceptance of forest management regimes. In both areas an early, rapid expansion of uncontrolled timber removal and in the number of operating timber mills was followed by controlled exploitation, a rapid decline in the numbers of mills and, more recently, a general decline in yield. In neither case was increased con- cern about conservation responsible for the reduction in either yield or in employment in the indus- try. Rather, in WA jarrah forests, amendments in purpose and tenure were subsequent to the loss of most mills and towns, while in southern Africa’s Afromontane forests, timber workers were pen- sioned by 1939 because of scanty remaining merchantable timber.

  • Proteaceae (Banksia Species)
    Proteaceae (Banksia Species) Information: 90% of all Banksia species occur in South Western Australia. The two most com- mon Banksia species in the Perth region are the Firewood Banksia (Banksia menziesii) and the Slender or Candle Banksia (Banksia attenuata). These two species each flower throughout the two halves of the year and are an important source of food for countless animals. Large Banksias such as these as well as B. grandis, B. ilicifolia B. Prionotes and B. littoralis produce an abun- dance of nectar from their large flower spikes that sustain countless species and have traditionally been used as a source of food and drink by indigenous Australians. Banksias are highly adapted to a nutrient poor environment with harsh, dry climate having sunken stomata to preserve water and cluster roots to enhance nutrient uptake in Phosphorus deficient soils.

  • Seed Dispersal by Ants in Jarrah Forest Restorations of Western Australia
    Seed Dispersal by Ants in Jarrah Forest Restorations of Western Australia Troy L. Wanless Introduction The jarrah forests in Western Australia cover approximately 1.75 million ha in the southwestern corner of the state (Figure 1). Jarrah, otherwise known as Eucalyptus marginata, is only one species among many that inhabit a region with considerable physical and biological diversity. 1200 species of plants, 29 mammalian species, 45 reptile species, 17 frog species, 4 fish species and 150 bird species live in this system which also has highly adverse conditions for survival. These may include infertile, often salt-laden soils, drought, and the occasional wildfire (Western Australia Forest Alliance, 2003). Considerable deposits of bauxite, which is the primary material involved in the production of aluminum, are scattered throughout the region. Since 1963, Alcoa of Australia Ltd. has cleared these jarrah forests to make way for mining of this ore. It is estimated that these deposits cover 7-8% of the forested area although only 3-4% will ever be mined due to environmental and economic constraints (Majer, 1989). These mined areas create a scattering of patches throughout the forest that are essentially stripped of any kind of biodiversity that was once there (Figure 2). Restoration efforts on these previously mined patches focus on many aspects of the jarrah forest ecosystem. Specifically interesting is the role that ants play in seed dispersal. This paper will focus on the topic of seed dispersal by ants in the northern jarrah forests of Western Australia while paying particular attention to myrmecochory. Figure 1.
