    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups. Groups notnot yet yet covered covered in inANHAT ANHAT are notnot included included in in the the list. list. • The data used come from authoritative sources, but they are not perfect. All species names have been confirmed as valid species names, but it is not possible to confirm all species locations.

  • Labiatae) in South-Eastern Australia
    319 Contributions to the systematics of Prostanthera (Labiatae) in south-eastern Australia Barry J. Conn Abstract Conn, B.J. (Royal Botanic Gardens, Mrs Macquaries Road, Sydney NSW 2000, Australia) 1997. Contributions to the systematics of Prostanthera (Labiatae) in south-eastern Australia. Telopea 7(4): 319–332. Prostanthera cuneata is regarded as endemic to mainland Australia, with the type material based on cultivated material grown in Formosa garden, Tasmania. The new species Prostanthera galbraithiae B.J.Conn is here formally described. A morphological re-evaluation of Prostanthera melissifolia concludes that this species is endemic to Victoria. Prostanthera melissifolia sensu Conn, from the Northern Tablelands of New South Wales, is P. caerulea R.Br., and Prostanthera sp. aff. melissifolia sensu Beauglehole, from East Gippsland (Victoria), probably is P. incisa R.Br. (s. lat.). A full description, habitat notes, distribution map and illustration of each of the first three species are provided. Introduction This paper presents the conclusions of revisionary studies into the genus Prostanthera section Prostanthera, arising particularly from work towards the preparation of an account of the genus for the forthcoming Flora of Victoria, volume 4. Terminology follows Conn (1984), except inflorescence terminology as modified by Conn (1995). Distribution information for Victoria follows Conn (1993). 1. Distribution of Prostanthera cuneata Benth. Previously, Prostanthera cuneata has been regarded as occurring in New South Wales, Tasmania and Victoria. Although the type specimen of this species (Gunn 725, 7 Dec. 1842) is stated to have been collected from the ‘South Esk’ River, south of Launceston in Tasmania, Buchanan (1988, 1990) states that Gunn actually collected from ‘Formosa’ garden, on the estate of W.E.

  • Action Statement
    Action Statement Flora and Fauna Guarantee Act 1998 No. 2 31 Wellington Mint-bush Prosthanthera galbraithiae This Action Statement is based on a draft Recovery Plan prepared for this species by DSE under contract to the Australian Government Department of the Environment, Water, Heritage and the Arts. Description Wellington Mint-bush (Prostanthera galbraithiae ) is an erect or spreading shrub, 0.3–2 m tall (Walsh & Entwisle 1999). Young branches have a square- shaped cross-section, and are densely hairy between two faint lateral-running ridges and on nodes; the rest of the branch is hairless (Walsh & Entwisle 1999). The leaves are stalkless, arise in opposite pairs and have a slight aroma when crushed (Walsh & Entwisle 1999). They are linear, narrowly ovate or oblong, ~15 x 2 mm, mid green and mostly hairless (Walsh & Entwisle 1999). Flowers appear from September through to November, and are generally deep mauve to purple with deep mauve to purple spots in the throat. Distribution in Victoria The two upper petals form a hood and the three (Flora Information System DSE 2007) lower petals form a fan shape. The petals are 7 - 10 mm long; the middle petal of the lower three, however, is broader and longer than each of the two upper petals (Walsh & Entwisle 1999). The stamens have anthers which lack a basal appendage. The surrounding calyx is divided into two lips, the upper lip (curved backwards) grows to 5.5 mm in length. Eight to 24 flowers appear in a leafy, branched inflorescence that may be branched or unbranched. Distribution Abundance Wellington Mint-bush is restricted to the Holey It is estimated that over 1000 individuals exist in Plains State Park in the Gippsland Plains in Victoria 13 populations.

  • Topic 27: GRASSES (Poaceae)
    Australian Plants Society NORTH SHORE GROUP Ku-ring-gai Wildflower Garden Topic 27: GRASSES (Poaceae) Did you know that, Grass pollen first appeared in fossil record 50 million years ago, at the start of the Eocene period. They are thought to have evolved alongside grazing mammals. Poaceae is one of the most diverse and abundant plant groups. Worldwide it contains 700 genera and 10,000 species. In Australia there are 220 genera and 1,230 species. 30% are introduced. They are adapted to a wide range of habitats from alpine to warm tropical savannah regions where there is plenty of sun, moisture and warmth. The Importance of Grasses They are of great economic importance and have made human civilization possible. It is estimated that grasses supply 60% of the world’s food. All of the cereal grains: wheat, rice, maize, oats, barley, rye, sorghum and millet are grasses. The meat, poultry, dairy and wool growing industries depend on grazing or cereals. Sugar cane and bamboo are grasses. Grasses form the basis of natural ecosystems such as grasslands. Why are grasses so successful? They produce large quantities of seed which are spread by wind, water and animals. Some have hooks, hairs or awns to facilitate this. They can survive adverse conditions by reproducing vegetatively from buds on underground stems. This enables survival from drought and fire. They are wind pollinated and produce large quantities of pollen. The flowers are small, green and inconspicuous as they do not need to attract pollinators. Grasses are Monocotyledons These are herbaceous plants which have one seed leaf (cotyledon), strap-like leaves with parallel veins, a fibrous root system and usually no woody material.

I give consent to this copy of my thesis, when deposited in the University Library, being made available for loan and photocopying subject to the provisions of the Copyright Act 1968. Statement of Collaboration I hereby certify that the concepts embodied in Chapter 2 of this thesis have been done in collaboration with a fellow researcher at this university. I have included as part of the thesis in Chapter 2 a statement clearly outlining the extent of collaboration with whom and under what auspices. Stephen A. J. Bell Preface “The vegetated landscape …. on first appearance presents a bewildering display of living matter, a higgledy-piggledy mass of trunks, leaves, branches, shrubs and grasses seemingly without form. The more observant may notice that the higgledy-piggledy mass varies from one place to another, that in some places there are trees as tall as large buildings while in other places there are no trees at all …. By the application of a systematic approach to viewing vegetation the bewildering display of plant life can take on new meaning thus altering one’s perception of what is being seen .… Suddenly the jumble of plant life reveals structures and beauties probably hitherto unseen”.
