  • 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.

  • Ecology of Proteaceae with Special Reference to the Sydney Region

Bradstock Myerscough, P.J.1, Whelan, R.J.2, and Bradstock, R.A.3 (1Institute of Wildlife Research, School of Biological Sciences (A08), University of Sydney, NSW 2006; 2Department of Biological Sciences, University of Wollongong, NSW 2522; 3Biodiversity Research and Management Division, NSW National Parks & Wildlife Service, PO Box 1967, Hurstville, NSW 1481) Ecology of Proteaceae with special reference to the Sydney region. Cunninghamia 6(4): 951–1015. In Australia, the Proteaceae are a diverse group of plants. They inhabit a wide range of environments, many of which are low in plant resources. They support a wide range of animals and other organisms, and show distinctive patterns of distribution in relation to soils, climate and geological history. These patterns of distribution, relationships with nutrients and other resources, interactions with animals and other organisms and dynamics of populations in Proteaceae are addressed in this review, particularly for the Sydney region. The Sydney region, with its wide range of environments, offers great opportunities for testing general questions in the ecology of the Proteaceae. For instance, its climate is not mediterranean, unlike the Cape region of South Africa, south- western and southern Australia, where much of the research on plants of Proteaceae growing in infertile habitats has been done. The diversity and abundance of Proteaceae vary in the Sydney region inversely with fertility of habitats. In the region’s rainforest there are few Proteaceae and their populations are sparse, whereas in heaths in the region, Proteaceae are often diverse and may dominate the canopy.

  • Ecology of the Ecological Community
    APPENDIX A: BIOLOGY AND ECOLOGY OF THE ECOLOGICAL COMMUNITY This appendix provides further relevant information about the biology and ecology of the KI Narrow-leaved Mallee Woodland ecological community to better understand what the ecological community is and how it functions. Biology of key species The dominant presence of Eucalyptus cneorifolia in the tree canopy is a diagnostic feature of the ecological community. The KI narrow-leaved mallee is an upright tree, to ten metres tall, sometimes with a single stem or in the form of a multi-stemmed mallee (Brooker et al., 2002). It generally forms a dense canopy of narrow, dark green leaves. The leaves have conspicuous oil glands and the species was used for the Eucalyptus oil industry (Willoughby et al., 2001). The KI narrow-leaved mallee develops a lignotuber at the base of the trunk. Regeneration after disturbances, such as fire, occurs mostly through resprouts from the lignotuber. Regeneration from canopy-stored seed or from the soil seed bank is thought to be limited (Rawson et al., 2012). Other plant species may be widespread throughout the ecological community, for instance Melaleuca uncinata (broombrush), M. lanceolata (dryland tea-tree) or Thryptomene ericaea (heath thryptomene) are common at many sites. However, no other plant species occurs across all sites nor has such an obvious presence that it governs the structure and appearance of the ecological community. Similar considerations apply to the faunal component of the ecological community. The upper height limit for mallee eucalypts is typically about 9 metres (Parsons, 1994). An unusual feature of mallees on KI is that they can be taller, sometimes exceptionally so.

  • St Kilda Wetlands Restoration Workshop Report
    St Kilda Wetlands Restoration Workshop Report Scope The scope of this Workshop Report includes consideration of recovery actions achievable within land managed by Salisbury Council and the Department for Environment and Water (DEW) including the Adelaide International Bird Sanctuary National Park (Winaityinaityi Pangkara), and Crown lands. Recovery actions on Freehold land or land currently under Mining Production Lease are not the focus of this document but were considered in the workshop with a view to informing long-term integrated management of the area. The recommended actions arising from the workshop included in this report will form the basis of an action plan/s for recovery of impacted areas. Background Following removal of the key threatening process (hypersaline groundwater mounding) the wetlands and surrounding vegetation will begin to recover to some degree. The ability for colonising plants to germinate and survive will be influenced by the speed at which salt can be flushed from the soil by tidal movement and rainfall. It is unknown how long this process will take, it is likely it could take years. Once salt has been sufficiently depleted from the system, passive regeneration will begin to occur in some species such as mangroves, through propagule migration from un-impacted areas, and some samphire/saltmarsh species, provided a seed source is nearby or some plants that can reproduce vegetatively have survived. Although species will regenerate, the structure of the vegetation is likely to be significantly altered with loss of different age classes. There is also uncertainty around mangrove regeneration where biomass of dead and decaying mangrove forest may act as a barrier for landward mangrove propagule migration.
