  • 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.

An ecological community is a unique and naturally occurring group of plants and animals. Its presence and distribution is determined by environmental factors such as soil type, position in the landscape, climate and water availability. Species within such communities interact and depend on each other - for example, for food or shelter. Examples of communities listed under the EPBC Act include woodlands, grasslands, shrublands, forests, wetlands, ground springs and cave communities. Together with threatened species, ecological Management Authority Tropics © Wet communities are protected as one of several matters Ptilinopus superbus, superb fruit dove. Listed Marine Species of National Environmental Significance under the EPBC Ecological communities provide a range of ecosystem Act.

  • Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
    Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.

Summary LÜTTGE U. 2000. Light-stress and crassulacean acid metabolism. - Phyton (Horn, Austria) 40 (3): (65) - (82). Environmental cues driving the evolution and diversification of plants with crassulacean acid metabolism (CAM) are widely accepted to have been primarily CO2 (HCO3") supply and subsequently H2O supply. Light-stress is largely considered to act via amplification of water stress. Can light-stress per se affect CAM? CAM plants show various ways of acclimation to high light. In the field sun exposed CAM plants (e.g. rosettes of bromeliads, Aloe; Kalanchoe species) often respond with changes of pigmentation from dark green to strongly red or yellow. Changes in xanthophyll-cycle capacity serving thermal dissipation of excess photosynthetic excitation energy have been shown. Acclimation often seems to be strongly related to N-nutrition. CAM plants are known to be subject to acute and chronic photoinhibition. This was mostly related to phases when they perform C3-photosynthesis, i.e. in the early morning (phase II) and especially in the afternoon (phase IV).

The Xanthorrhoeaceae has the largest representation with 10 genera and 99 species. Most are endemic with a few species of Lomandra and Romnalda extending to neighbouring islands. The family includes the spectacular blackboys and grass-trees. The Iridaceae is largely represented by naturalised species with 52 of the 78 species being introduced. Many of the introductions are ornamentals and several have become serious weeds. Patersonia is the largest genus with all 17 species endemic. Some of these are cultivated as ornamentals. The Dioscoreaccae is a family of economic significance, particularly in the old world tropics where some species are cultivated or collected for their tubers and bulbils. In Australia there are 5 species, one of which is a recent introduction. The endemic and native species, commonly known as yams, are traditionally eaten by the Aborigines.
