Vegetation on Fraser Island
Vegetation On Fraser Island Imagine towering pines, rainforest trees with three metre girths, rare and ancient giant ferns, eucalypt forests with their characteristic pendulous leaves, lemon-scented swamp vegetation and dwarfed heathland shrubs covered in a profusion of flowers. Now imagine them all growing on an island of sand. Two of Fraser Island’s unique features are its diversity of vegetation and its ability to sustain this vegetation in sand, a soil that is notoriously low in nutrients essential to plant growth. Plants growing on the dunes can obtain their nutrients (other than nitrogen) from only two sources - rain and sand. Sand is coated with mineral compounds such as iron and aluminium oxides. Near the shore the air contains nutrients from sea spray which are deposited on the sand. In a symbiotic relationship, fungi in the sand make these nutrients available to the plants. These in turn supply various organic compounds to the fungi which, having no chlorophyll cannot synthesise for themselves. Colonising plants, such as spinifex, grow in this nutrient poor soil and play an integral role in the development of nutrients in the sand. Once these early colonisers have added much needed nutrients to the soil, successive plant communities that are also adapted to low nutrient conditions, can establish themselves. She-oaks ( Allocasuarina and Casuarina spp.) can be found on the sand dunes of the eastern beach facing the wind and salt spray. These hardy trees are a familiar sight throughout the island with their thin, drooping branchlets and hard, woody cones. She-oaks are known as nitrogen fixers and add precious nutrients to the soil. -
Tasmannia Lanceolata
ASPECTS OF LEAF AND EXTRACT PRODUCTION from Tasmannia lanceolata by Chris Read, B. Agr.Sc. Tas. Submitted in fulfillment of the requirements for the Degree of Doctor of Philosophy University of Tasmania, Hobart December 1995 ' s~, ... ~~ \ ·'(11 a_C\14 \t\J. \I ' This thesis contains no material which has been accepted for the award of any other degree or diploma in any University, and to the best of my knowledge, contains no copy or paraphrase of material previously written or published by any other person except where due reference is given in the text. University of Tasmania HOBART March 1996 This thesis may be made available for loan and limited copying in accordance with the Copyright Act 1968 University of Tasmania HOBART March 1996 Abstract This thesis examines several aspects of the preparation, extraction and analysis of solvent soluble compounds from leaf material of Tasmannia lanceolata and reports a preliminary survey of extracts of some members of the natural population of the species in Tasmania. A major constituent of these extracts, polygodial, was shown to be stored within specialised idioblastic structures scattered throughout the mesophyll, and characterised by distinctive size and shape, and a thickened wall. The contents of these cells were sampled directly, analysed and compared with the composition of extracts derived from ground, dry whole leaf. This result was supported by spectroscopic analysis of undisturbed oil cells in whole leaf tissue. In a two year field trial, the progressive accumulation of a number of leaf extract constituents (linalool, cubebene, caryophyllene, germacrene D, bicyclogermacrene, cadina-1,4 - diene, aristolone and polygodial) during the growth flush was followed by a slow decline during the subsequent dormant season. -

Epacris Study Group
ASSOCIATION OF SOCIETIES FOR GROWING AUSTRALIAN PLANTS Inc. EPACRIS STUDY GROUP Group Leader: Gwen Elliot, P.O. Box 655 Heathmont Vic. 3135 NEWSLETTER No. XS (ISSN 103 8-6017) Qctaber zaQ4 Greetings as once again we begin to enjoy the longer days of spring-summer and the encouragement this provides for many of our flowering plants. Despite the generally dry conditions many Epacris species are putting on outstanding floral displays. How are you going with your recording of the flowering times of Epacris impressa in your garden, as well as in nearby bushland or in other areas as you travel within Australia? It really is quite an exciting project because together we, as Study Group members, can make a real contribution to the overall understanding of this species, adding to the knowledge and research of botanists who look in detail at the features of the plant under the microscope and in its natural habitat. It iis a species which occurs both atsea-level and at higher altitudes. How are the flowering times affected when highland plants are cultivated at lower altitudes? Are flowering times different when plants fiom New South Wales for example are gvown much further south in soulhern Victoria or Tasmania ? Epacris impressu seems like an excellent species for us to research in this way. If our project is successful we may perhaps be able to continue with looking at the flowering times of other Epacris which are relatively common in cultivation. In case you have misplaced the recording sheet from our October 2003 Newsletter, another is included in this issue. -

This method involves the collection of samples two sampling techniques: slow-flowing river edges (dip- net technique) and fast-flowing riffles (kick-net technique). Macroinvertebrates were live-picked from the samples while in the field, preserved in 70% ethanol and later identified in the laboratory to family level or other taxonomic resolutions stipulated in the AUSRIVAS protocol (Tiller & Metzeling 2002). Results were then analysed using the AUSRIVAS software package, which contains predictive models that assess the ecological health of a monitoring reach by comparing its macroinvertebrate community with those of similar undisturbed reaches within the model. Backpack electrofishing was undertaken at four sites using a Smith Root LR-24 backpack electrofisher. Backpack electrofishing consisted of 500 second of ‘power on’ time at each site. Ten bait traps constructed of 2 millimetre mesh with entrance funnels of 40 millimetre in diameter were set overnight at Rocky Valley Creek Downstream site. Bait traps were deployed in depths of 0.25 to 0.5 metres, typically amongst cover of aquatic vegetation or other forms of cover. -
Gum Trees Talk Notes
Australian Plants Society NORTH SHORE GROUP Eucalyptus, Angophora, Corymbia FAMILY MYRTACEAE GUM TREES OF THE KU-RING-GAI WILDFLOWER GARDEN Did you know that: • The fossil evidence for the first known Gum Tree was from the Tertiary 35-40 million years ago. • Myrtaceae is a very large family of over 140 genera and 3000 species of evergreen trees and shrubs. • There are over 900 species of Gum Trees in the Family Myrtaceae in Australia. • In the KWG, the Gum Trees are represented in the 3 genera: Eucalyptus, Angophora & Corymbia. • The name Eucalyptus is derived from the Greek eu = well and kalyptos = covered. BRIEF HISTORY E. obliqua The 18th &19th centuries were periods of extensive land exploration in Australia. Enormous numbers of specimens of native flora were collected and ended up in England. The first recorded scientific collection of Australian flora was made by Joseph Banks and Daniel Solander, during Sir James Cook’s 1st voyage to Botany Bay in April 1770. From 1800-1810, George Caley collected widely in N.S.W with exceptional skill and knowledge in his observations, superb preservation of plant specimens, extensive records and fluent expression in written records. It is a great pity that his findings were not published and he didn’t receive the recognition he deserved. The identification and classification of the Australian genus Eucalyptus began in 1788 when the French botanist Charles L’Heritier de Brutelle named a specimen in the British Museum London, Eucalyptus obliqua. This specimen was collected by botanist David Nelson on Captain Cook’s ill- fated third expedition in 1777 to Adventure Bay on Tasmania’s Bruny Is. -

Post-Fire Recovery of Woody Plants in the New England Tableland Bioregion
Post-fire recovery of woody plants in the New England Tableland Bioregion Peter J. ClarkeA, Kirsten J. E. Knox, Monica L. Campbell and Lachlan M. Copeland Botany, School of Environmental and Rural Sciences, University of New England, Armidale, NSW 2351, AUSTRALIA. ACorresponding author; email: [email protected] Abstract: The resprouting response of plant species to fire is a key life history trait that has profound effects on post-fire population dynamics and community composition. This study documents the post-fire response (resprouting and maturation times) of woody species in six contrasting formations in the New England Tableland Bioregion of eastern Australia. Rainforest had the highest proportion of resprouting woody taxa and rocky outcrops had the lowest. Surprisingly, no significant difference in the median maturation length was found among habitats, but the communities varied in the range of maturation times. Within these communities, seedlings of species killed by fire, mature faster than seedlings of species that resprout. The slowest maturing species were those that have canopy held seed banks and were killed by fire, and these were used as indicator species to examine fire immaturity risk. Finally, we examine whether current fire management immaturity thresholds appear to be appropriate for these communities and find they need to be amended. Cunninghamia (2009) 11(2): 221–239 Introduction Maturation times of new recruits for those plants killed by fire is also a critical biological variable in the context of fire Fire is a pervasive ecological factor that influences the regimes because this time sets the lower limit for fire intervals evolution, distribution and abundance of woody plants that can cause local population decline or extirpation (Keith (Whelan 1995; Bond & van Wilgen 1996; Bradstock et al.
