  • NEWSLETTER No. 93 November 2004
    ISSN 1035-4638 ASSOCIATION OF SOCIETIES FOR GROWING AUSTRALIAN PLANTS ACACIA STUDY GROUP NEWSLETTER No. 93 November 2004 Dear Members South east Qld has at last received very welcome rain. Some areas received very heavy falls indeed but the drought is far from over and forecasters are suggesting that the climate in this region is changing. As in parts of WA, our climate appears to be heading for a drier period. With the prospect of a continuing increase in population in the area, the need to conserve water is very much to the fore. Old habits diehard and brilliantly flowered, water hungry annuals are still in great demand in nurseries and green lawns are still considered the way to go. At some stage there must be a serious rethink of what is promoted for gardens. Even wet rainforest trees have been suffering in Brisbane and I know of people who have lost plants 5 to 6m tall in rainforest plots because it was assumed that the rainfall was adequate for their needs. If the future is as predicted, it will become uneconomical to keep such plants alive as the cost of water rises. My ceaseless promotion of acacias now stresses even more the drought hardiness of many species and I do have a few more listeners. After a bumper harvest last year I have not been able to collect any seed from the acacias at Booie this year. Apart from the ‘dry’ the starving wildlife has been taking its toll. Where flowers did manage to open, the branches were broken down so the flowers could be eaten and any seed that did form was also eaten.

    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.

  • Plant Life of Western Australia
    PART V The Flora of extra-tropical Western Australia and it’s classification. CHAPTER I. FLORISTIC SUBDIVISION OF THE REGION To correctly interpret the interesting floristic features of south-western Australia, the extensive use of statistical data is required. Since, however, such data are as yet inadequate, the best one can do is to provide a suitable foundation to enable a critical study of the facts. I have therefore examined and assessed all my data so as to achieve a uniform standard. The fact that these figures may be subject to considerable change in the future does not affect their usefulness. This was made clear by J. D. Hooker when he said “it is not from a consideration of specific details that such problems as those of the relationships between Floras and the origin and distribution of organic forms will ever be solved, although we must eventually look at these details for proofs of the solu- tions we propose”. The division of extra-tropical Western Australia into two distinct regions i.e. the Eremaean and the Southwest Province, has so far received most attention. Their ap- proximate boundaries were first recorded by Ferdinand von Müller. In several of his publications he refers to the importance of a line running from Shark Bay to the west side of the Great Bight, as separating the two Provinces. This line coincides, more or less , with the 30 cm isohyet which divides the arid interior from the coastal region. This line is also important from the standpoint of land settlement since it also marks the limit of the area where wheat can be successfully grown.

Do mutualists matter? The role of pollinators, seed dispersers and belowground symbionts in the invasion success of Acacia __________________________________ A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University by Elizabeth M. Wandrag _______________________________ Lincoln University, New Zealand 2012 Abstract Plant species introduced to new locations may lose their natural enemies but can also leave behind important mutualists. Here, I take a novel comparative approach to identify the potential role of mutualistic interactions in determining invasion outcomes. I examine the strength of pollination, seed dispersal and belowground symbioses with nitrogen-fixing bacteria (rhizobia) across three species that vary in invasion success in both their introduced and native range. I used species of Australian Acacia introduced to New Zealand. I hypothesised that if interactions with mutualists are important for plant invasion then species would vary in the strength of interactions with one or more of the groups of mutualists I examined, and that the pattern of variation would correlate with the degree to which they have established and spread in New Zealand.
