Linnaeus is situated toward the upper left hand side of the image. The 200 million year old metasediment hills meet the coastal sands at Linnaeus and Broken Head Nature Reserve. These here hills are as old as the trees forms the flats. Lennox Head is an old lava flow not completely eroded away. This landscape tells a story, a tale that stretches back 200 million years. At that time Australia was part of the super-continent Gondwana and a deep ocean trench occupied the space where Linnaeus is situated today. Meanwhile the sandstone and granite mountain ranges of New Clays, silts and sands transported by streams and rivers from nearby eroding plateaus deposited layers in South Wales were gradually eroding away, pulverised over the ocean trench. Over time these sediments consolidated into rocks that were buckled and uplifted, and in millions of years by the action of water and ultimately deposited turn eroded into a landscape of hills and valleys. into the ocean as sand. The prevailing southeast winds and waves pushed this sand up against the coast and gradually northward, Volcanic activity followed around 20 million years ago, covering this landscape with a super-volcano over forming the beaches and coastal dunes of northern NSW. 100km in diameter. The volcano was centred on present-day Wollumbin (Mt Warning), a one-hour drive northwest of the Estate. This mountain, the ancient plug of the volcano, can be seen from the beaches of Byron Bay. Over time, high rainfall formed streams and rivers that partially eroded away the overlying volcanic rocks, leaving behind a gigantic erosion crater known as a caldera (the Tweed Valley) with Mt Warning at its centre. Radiating outward from the rainforest-clad crater rim, like spokes in a wheel, countless fresh-flowing The Hoop Pine Araucaria cunningamii belongs to an ancient group streams cut deep gorges and broad valleys into the landscape. It was this erosion that revealed and shaped of conifers that includes the recently discovered Wollemi Pine. This the metasediments that form the hills of the Linnaeus Estate today and deposited much of the material that family of conifers goes back 200 million years in the fossil record, making it literally as old as the hills. 12 i.

    Botanical Name: Acacia Common Name: Wattle Family: Fabaceae Origin: Australia and Africa Habit: various habitats Author: Diana Hughes, Mullumbimby I like to turn to PlantNET-FloraOnline to learn more about plants. Here you will find a wealth of information about plants, their growing habits and distribution. Much can be learnt from Latin names given, plus the variety of common names attributed to each plant. A more familiar name for Acacia is Wattle - Australia's floral emblem, in this case Acacia pycantha, Golden Wattle, which is native to South Eastern Australia. We have beautiful wattles in our region, most of which are coming into flower now. Mullumbimby is famous for the rare Acacia bakeri, (Marblewood), a rainforest species. It is found on the banks of the Brunswick River, with insignificant white flowers, hidden in glossy leaves. Searches through several websites confirm my fears that many Acacias are considered as needing 'environmental management' - meaning they have weed potential. But who could find a field of beautiful Queensland Silver Wattle an unpleasant sight? Negatively they are 'seeders', and positively, they are nitrogen fixers. Managing the four species in my garden is a pleasure. My pride and joy is an Acacia macradenia, or Zig Zag wattle because its phyllodes (leaves) are arranged in that manner along weeping branches. It's about to flower for the 6th year. Motorists stop to photograph it as it is such a sight. I prune it hard each year. My rear raised garden bed holds 3 different species. The well-known Queensland Silver Wattle, or Mt Morgan wattle (Acacia podalyriifolia) is now flowering.

Karen A. Johnson iii iv Abstract Relationships between plants and their pollinators are thought to have played a major role in the morphological diversification of angiosperms. The epacrids (subfamily Styphelioideae) comprise more than 550 species of woody plants ranging from small prostrate shrubs to temperate rainforest emergents. Their range extends from SE Asia through Oceania to Tierra del Fuego with their highest diversity in Australia. The overall aim of the thesis is to determine the relationships between epacrid floral features and potential pollinators, and assess the evolutionary status of any pollination syndromes. The main hypotheses were that flower characteristics relate to pollinators in predictable ways; and that there is convergent evolution in the development of pollination syndromes.

  • 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.

  • 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.
