  • State-Wide Seed Conservation Strategy for Threatened Species, Threatened Communities and Biodiversity Hotspots
    State-wide seed conservation strategy for threatened species, threatened communities and biodiversity hotspots Project 033146a Final Report South Coast Natural Resource Management Inc. and Australian Government Natural Heritage Trust July 2008 Prepared by Anne Cochrane Threatened Flora Seed Centre Department of Environment and Conservation Western Australian Herbarium Kensington Western Australia 6983 Summary In 2005 the South Coast Natural Resource Management Inc. secured regional competitive component funding from the Australian Government’s Natural Heritage Trust for a three-year project for the Western Australian Department of Environment and Conservation (DEC) to coordinate seed conservation activities for listed threatened species and ecological communities and for Commonwealth identified national biodiversity hotspots in Western Australia (Project 033146). This project implemented an integrated and consistent approach to collecting seeds of threatened and other flora across all regions in Western Australia. The project expanded existing seed conservation activities thereby contributing to Western Australian plant conservation and recovery programs. The primary goal of the project was to increase the level of protection of native flora by obtaining seeds for long term conservation of 300 species. The project was successful and 571 collections were made. The project achieved its goals by using existing skills, data, centralised seed banking facilities and international partnerships that the DEC’s Threatened Flora Seed Centre already had in place. In addition to storage of seeds at the Threatened Flora Seed Centre, 199 duplicate samples were dispatched under a global seed conservation partnership to the Millennium Seed Bank in the UK for further safe-keeping. Herbarium voucher specimens for each collection have been lodged with the State herbarium in Perth, Western Australia.

    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.

  • Diagnostic 1 Location
    Flora and fauna assessment for the Calingiri to Wubin study areas Prepared for Muchea to Wubin Integrated Project Team (Main Roads WA, Jacobs and Arup) Appendix 6 Key to determining presence of the EPBC Act listed TEC Eucalypt woodlands of the Western Australian Wheatbelt Description based on Department of the Environment (2015a): The Eucalypt woodlands of the Western Australian Wheatbelt TEC is composed of eucalypt woodlands dominated by a complex mosaic of eucalypt species with a single tree or mallet form over an understorey that is highly variable in structure and composition. A mallet habit refers to a eucalypt with a single, slender trunk and steep- angled branches that give rise to a dense crown. Many eucalypt species are considered iconic within the Wheatbelt landscape, for example, Eucalyptus salmonophloia (salmon gum), E. loxophleba subsp. loxophleba (York gum), Eucalyptus rudis subsp. rudis, E. salubris (gimlet), E. wandoo (wandoo) and the mallet group of species. Associated species may include Acacia acuminata (jam), Corymbia calophylla (marri) and Eucalyptus marginata (jarrah). The understorey structures are often bare to sparse, herbaceous, shrub of heath, chenopod-dominated, thickets (Melaleuca spp.) and saline areas with Tecticornia spp. The main diagnostic features include location, minimum crown cover of the tree canopy of 10% in a mature woodland, presence of key species and a minimum condition according to scale of Keighery (1994) that depends on size of a patch, weed cover and presence of mature trees. A patch is defined as a discrete and mostly continuous area of the ecological community and may include small-scale variations and disturbances, such as tracks or breaks, watercourses/drainage lines or localised changes in vegetation that do not act as a permanent barrier or significantly alter its overall functionality.

  • Approved Conservation Advice (Including Listing Advice) for the Eucalypt Woodlands of the Western Australian Wheatbelt
    Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) Approved Conservation Advice (including listing advice) for the Eucalypt Woodlands of the Western Australian Wheatbelt 1. The Threatened Species Scientific Committee (the Committee) was established under the EPBC Act and has obligations to present advice to the Minister for the Environment (the Minister) in relation to the listing and conservation of threatened ecological communities, including under sections 189, 194N and 266B of the EPBC Act. 2. The Committee provided its advice on the Eucalypt Woodlands of the Western Australian Wheatbelt ecological community to the Minister as a draft of this conservation advice. In 2015, the Minister accepted the Committee’s advice, and adopted this document as the approved conservation advice. 3. The Minister amended the list of threatened ecological communities under section 184 of the EPBC Act to include the Eucalypt Woodlands of the Western Australian Wheatbelt ecological community in the critically endangered category. It is noted that Western Australia lists components of this ecological community as threatened. 4. A draft conservation advice for this ecological community was made available for expert and public comment for a minimum of 30 business days. The Committee and Minister had regard to all public and expert comment that was relevant to the consideration of the ecological community. 5. This approved conservation advice has been developed based on the best available information at the time it was approved; this includes scientific literature, advice from consultations, and existing plans, records or management prescriptions for this ecological community.

  • MVG 32 Open Mallee Woodlands and Sparse Mallee Shrublands DRAFT
    MVG 32 – OPEN MALLEE WOODLANDS AND SPARSE MALLEE SHRUBLANDS Triodia mallee, western NSW (Photo: B. Pellow) Overview Mallee Woodlands and shrublands are semi-arid systems dominated by eucalypt species that produce multiple stems from an underground rootstock known as a lignotuber. Some vegetation in non-arid regions also supports eucalypts with mallee growth forms, but these are not part of MVG 32 or MVG 14. Eucalypts are the most widespread tree component of this MVG however species of Callitris, Melaleuca, Acacia and Hakea may co-occur as trees at varying densities and may co-dominate mallee communities. An open tree layer (notionally < 10 % projective foliage cover, < 20% crown cover) distinguishes MVG 32 from MVG14 (Mallee Woodlands and Shrublands), which has a denser tree layer (notionally >10% foliage projective cover, >20% crown cover). However, this distinction is largely artificial, as tree cover varies spatially at fine scales and temporally with fire regimes, while the occurrence of tree, shrub and ground layer species shows little relationship to variations in eucalypt cover. Understorey composition is strongly influenced by rainfall, soil types and fire regime and can be dominated by hummock grasses (spinifex), chenopods or other woody shrubs. Some mallee woodlands are among the most fire prone of all plant communities in semi-arid and arid zones (Keith 2004).
