Plants of the West Coast family: fabaCeae Acacia cochlearis RIGID WATTLE (Labill.) H.L.Wendl Flowering period: July–October. Description: Bushy, erect to sprawling shrub, 0.5–3 m high and found as solitary plants or in thickets. Leaves to 45 mm long with a sharp point, rigid, with prominent parallel veins. Flower heads globular with up to three produced in each leaf axil. The green-brown pod is flat, to 50 mm long, and produces 10–15 black and usually highly viable seeds. Pollination: Open pollinated by a wide variety of non-specific insects. Sets a moderate amount of seed in good seasons. Distribution: From Lancelin to Israelite Bay where the species grows as solitary plants or in thickets in coastal to near-coastal habitats. Along the coast the species favours stable secondary dunes. Often an indicator of good quality dunes as the species is vulnerable to disturbance. Propagation: Grow from seed collected in December when pods mature. Seed should be hot water treated or lightly abraded with fine sandpaper. Sow in a free-draining soil mix and keep moist. Seedling growth may benefit from incorporation of a little soil taken from the weed- and disease-free soil surface around a parent plant to ensure transfer of the Rhizobium bacteria that are important in nitrogen nutrition of the plant. R. Barrett Habit Uses in restoration: A useful species that reliably establishes in stabilised soil. Must be protected from direct exposure to high winds and is best incorporated into mixed plantings with other shrubs including Acacia rostellifera and Scaevola crassifolia. Notes: As with many Acacia species the distinctive aril or food body attached to the Branches seed may aid in seed dispersal by insects and birds. An attractive, compact shrub for the home garden that requires a full sun position. R. Barrett Flowers Distribution 62 63.

The Effects of Fire and Quokkas (Setonix Brachyurus) on the Vegetation of Rottnest Island, Western Australia
Journal of the Royal Society of Western Australia, 86:49---60, 2003 The effects of fire and quokkas (Setonix brachyurus) on the vegetation of Rottnest Island, Western Australia Rippey M E1 & Hobbs R F 1 Department of Geography, University of Western Australia, Nedlands WA 6009 [8) [email protected] 2 School of Environmental Science, Murdoch University, Murdoch, WA 6150 [8) [email protected] (Manuscript received March 2002; accepted November 2002) Abstract Three different plant communities have dominated the vegetation of Rottnest Island over the past two centuries; low forest, Acacia rostellifera scrub, and sclerophyllous heath. In 1997 a fire burnt 90 ha of heathland and provided an opportunity to examine the relationships between dominant vegetation types, fire and grazing by quokkas (Setonix brachyurus). Our study and the literature indicated four major findings. • Burnt heath recovered slowly if grazed. If not grazed, heath regenerated rapidly to become dense, tall and weed-free compared with the surrounding heathland, and the number of native species increased. • Where there was no grazing, all three vegetation communities were able to become established immediately after the fire. Four and a half years after the fire, Acacia thickets dominated in some areas and reached 3-4 m in height, overshadowing a group of self-seeded Melaleuca seedlings and outcompeting heath species. It is anticipated that the Melaleuca will emerge and dominate when the shorter-lived Acacia declines, and that heath will continue to occupy open areas. • The three dominant vegetation communities can be regarded as stable state alternatives. Heath will dominate if there is heavy grazing, as the young trees and Acacia are palatable and so cannot regenerate.

Acacia rostellifera is one of 12 species of a group of closely related taxa referred to by Chapman & Maslin (1992) as the ‘Acacia bivenosa group’. Acacia rostellifera and A. salicina are the only members of this group detailed in the report. Acacia rostellifera is particularly closely related to the widespread arid zone species, A.

Some Case Studies of Acacia As Weeds and Implications for Herbaria
Some case studies of Acacia as weeds and implications for herbaria John C. Reid and Daniel J. Murphy Royal Botanic Gardens Melbourne, Birdwood Avenue, South Yarra, Victoria 3141, Australia; e-mail: [email protected] Introduction Abstract There are a number of striking examples of Australian Acacia spp. A context for Australian Acacia species (wattles) as weeds is provided, occurring as weeds in other countries (New 1984). For example, Roux both overseas and within Australia. (1961) documents the introduction of Acacia cyanophylla Lindl. (now Specific case studies from the western synonymous with A. saligna (Labill.)

Both species are major environmental provided by weedy acacias, including confusion between indigenous and weeds in South Africa (Orchard & Wilson 2001b), although the impact introduced species. Four species, one of A. saligna has been reduced in that country following release of a indigenous (Acacia uncifolia) and three genotype of the gall-forming rust Uromycladium tepperianum (Sacc.) introduced (A. cupularis, A. cyclops McAlpine (Wood & Morris 2007). and A. rostellifera), are described There are 1381 described species of Acacia sens. lat. worldwide, 993 and the reasons for their occurrence in the study area are investigated. of these occur in Australia, most of which are now in the genus Acacia Some key factors for the success of sens.

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.

Comparison of the Vegetation of the Islands in Shoalwater Bay (Rockingham, Western Australia) with That of the Coastal Bushland
Journal of the Royal Society of Western Australia, 85:169-179, 2002 Comparison of the vegetation of the islands in Shoalwater Bay (Rockingham, Western Australia) with that of the coastal bushland E Rippey1,2, J J Rippey2, B Green2 & J N Dunlop2 1Department of Geography, University of Western Australia. Crawley WA 6009 2Friends of the Shoalwater Islands Marine Park, 0 Rockingham Environmental Centre, Safety Bay Road, Rockingham WA 6168 email: [email protected] (Manuscript received May 2002; accepted November 2002) Abstract Surveys were conducted of the vegetation of three areas in and around Shoalwater Bay: a strip of foreshore (Mersey Point), a headland (Point Peron), and a string of islands. Each survey area measured about 15 ha. The differences between the two mainland reserves and the islands are of particular interest. Only 23% of the plant species recorded occurred in all three reserves. It appears that human activities have been directly responsible for many of the changes in the flora of the mainland reserves, while seabirds influence the plant cover of the islands. At Mersey Point, a large proportion of species appear to have been introduced by the dumping of garden rubbish. At Point Peron, the vegetation has been affected by frequent fires, so that fire-resistant species are favoured. On the islands, seabirds play a major role in determining the nature of the vegetation by virtue of their trampling and the guano that they deposit. The findings of this investigation provide a baseline for further monitoring and for evaluation of future management measures. Keywords: Shoalwater Bay, coastal vegetation, island vegetation, Western Australia Introduction Shoalwater Bay lies off the west coast at Rockingham, 50 km south of Perth.
