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.

  • 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. Firewood Banksia (Banksia menziesii) with parasitic ’witches broom’ (insert) Pictures by A. Price Candle Banksia (Banksia attenuata) feeding a Honey Possum (Tarsipes rostratus) Picture courtesy of Kwongan Foundation Associated Life: Many animals drink nectar from Banksia flower heads including Perching birds such as Honeyeaters, Spinebills, robins and Wagtails as well as the Honey Possum, the worlds only nectarvorious marsupial. Bull Banksia European Honeybees are commonly (Banksia Grandis) found in or near flower spikes as are wee- vils and jewel beetles.

  • 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.

(Firewood Banksia) and Banksia littoralis R.Br. (Swamp Banksia) (Pro- teaceae) grown in 1 m deep tubes filled with course sand and subjected to 140 days of drought. Both are tree species of the sandplains of mediterranean southwestern Australia. B. littoralis is restricted to low-lying, winter damp areas, inclu- ding the fringe of seasonal and permanent wetlands, whereas B. menziesii inhabits a range of habitats ranging from mid- upper slopes of deep, sandy dunes to dune crests. It was hypothesised that differences in their water relations and growth responses would reveal drought adaptation attributes that relates to their contrasting habitat preferences. For both spe- cies drought caused significant decreases in stomatal conductance and predawn xylem water potential. B. menziesii seedlings had a low stomatal conductance (< 0.1 mol m-2 s-1) and exhibited a desiccation avoidance response to drought by maintaining relatively higher water potential.

THE PERFORMANCE OF EUCALYPTUS SPECIES IN HILL COUNTRY A thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Plant Science at Massey University, Palmerston North, New Zealand. J ames Peter Millner 2006 Abstract Eucalyptus species, particularly stringybarks, which produce hard, durable wood are potentially useful in New Zealand, but most species are site sensitive. Twelve species (E. agglomerata, E. baxteri, E. botryoides, E. cladocalyx, E. globoidea, E. microcorys, E. muelleriana, E. nitens, E. obliqua, E. pilularis, E. regnans and E. sa ligna) were compared on four hill country microsites; upper and lower slope on sunny and shady aspects. Assessments included survival, foliar macro-nutrients, diameter at breast height (DBH), height, stem form, basic wood density and health to age 5 years. Site monitoring included solar radiation, temperature, rainfall and exposure. Foliar nutrients were strongly influenced by species and moderately influenced by microsite. Inter-nutrient and nutrient-growth correlations were identified and discussed. Subgeneric differences in nutrient profile were analysed with the aid of principal components analysis. Solar radiation and temperature were seasonal on both aspects but higher on the sunny face than the shady. Aspect differences were moderate, being greatest in the winter and least in the summer. A strongly seasonal growth pattern resulted, maximum DBH and height increments occurring in the spring and summer respectively.

  • Workshop Notes Perth Region Plant Biodiversity Project Jarrah Forest Reference Sites of the Perth Metropolitan Area: the Southe
    Workshop Notes Perth Region Plant Biodiversity Project Jarrah Forest Reference Sites of the Perth Metropolitan Area: The Southern Transect Shaun Molloy February 2008 Lithic complex (reference point MN2) Photograph by Shaun Molloy - 1 - Introduction Bush Forever is a 10 year strategic plan instigated by the Western Australian Government in conjunction with the general community and appropriate Local Government organisations to protect some 51,200 hectares of regionally significant bushland in 287 Bush Forever Sites, representing, where achievable, a target of at least 10 percent of each of the original 26 vegetation complexes of the Swan Coastal Plain portion of the Perth Metropolitan Region. Subsequent to Bush Forever, the Perth Biodiversity Project identified the need to catalogue and describe a series reference sites to facilitate consistency in the assessment of local natural areas and to further enhance the capacity of relevant people to undertake site recording tasks. To this end 40 reference sites were established based on Bush Forever on the Swan Coastal Plain part of the Perth Metropolitan Region (PMR) as part of the Perth Region Plant Biodiversity Project (PRPBP), a collaborative project between the WA Local Government Association’s Perth Biodiversity Project and the Department of Environment and Conservation. The PRPBP recognises a need to provide a fuller appreciation of the diversity of native vegetation found within the PMR. To that end, it was decided to establish reference sites within, or in close proximity to, Darling Plateau part of the PMR. It is proposed that these reference sites are established so as to represent major variations found in the plant communities found within this area thereby complementing reference sites already set up on the Swan Coastal Plain as part of the Perth Biodiversity Project.

  • Swamp Sheoak (Casuarina Obesa) Use in Farm Forestry by Tim Emmott, Greening Australia (WA)
    Swamp Sheoak (Casuarina obesa) use in Farm Forestry By Tim Emmott, Greening Australia (WA) Introduction This is an overview of the characteristics, management and use of Casuarina obesa as a farm forestry species. Casuarina obesa is not a new ‘miracle’ species for farm forestry. Rather, it has strengths in particular situations on farms in Western Australia. Casuarina growers, and documented information based on WA and eastern states experiences provide the sources for this publication. You should seek advice from farm forestry advisers before establishing this species for commercial purposes. Species Description Casuarina obesa is commonly known in Western Australia as swamp sheoak, Western Australian swamp oak, swampy oak, salt sheoak, grey sheoak, Kuli and Cooli. Swamp sheoak is a small tree growing to 14 metres, and has a dominant stem for much of its height when growing in closed stands on favourable sites and has a life span of more than 60 years. Generally, swamp sheoak trees have an erect trunk with erect, but sometimes spreading, branches. The bark is thick, fissured and darkish grey in colour. Natural Distribution Swamp sheoak grows widely in southern Western Australia, with limited occurrence in central South Australia, north western Victoria and south western New Open grown swamp sheoak near Northam WA. South Wales. In Western Australia, swamp sheoak naturally occurs in the yellow earthy sands, calcareous and sandy earths, and 275mm to 700mm per annum rainfall zone, growing grey cracking clays. around the margins of salt lakes and along saline creeks and The species is adaptable to most soils from sands to clays rivers throughout the Wheatbelt and Goldfields.

  • Seedling Growth and Physiological Responses of Two Sandplain Banksia Species Differing in Flood Tolerance
    Journal of the Royal Society of Western Australia, 87:115–121, 2004 Seedling growth and physiological responses of two sandplain Banksia species differing in flood tolerance P K Groom Centre for Ecosystem Management, School of Natural Sciences, Edith Cowan University, 100 Joondalup Drive, Joondalup, WA 6027 Current address: Centre for Horticulture and Plant Sciences, University of Western Sydney, Locked Bag 1797, Penrith South DC, NSW 1797 [email protected] (Manuscript received: March 2004; accepted February 2005) Abstract Banksia littoralis (Proteaceae) inhabits winter-wet locations and wetland fringes that are prone to seasonal flooding events on the Swan Coastal Plain. To survive in these locations, B. littoralis seedlings must be able to tolerate periods of flooding or complete submergence if establishment is to be successful. Flood tolerance was assessed in seedlings of B. littoralis subjected to 104 days of continual soil waterlogging by comparing changes in seedling growth and leaf ecophysiology with those of well-watered plants. Flood tolerance was also assessed in seedlings of Banksia prionotes, a species that grows in drier locations on the Swan Coastal Plain. As expected, B. prionotes was unable to survive long periods of soil waterlogging or submergence (97% mortality after 72 days of flooding). Both species responded to flooding by closing their stomates and reducing photosynthetic capacity, although B. littoralis was able to recover lost photosynthetic potential when flooded conditions subsided. After 72 days of flooding, there was a substantial decrease in relative growth rate in flooded B. prionotes seedlings, compared to that of well-watered plants, although this was not associated with significant differences in biomass allocation.
