2019 Proposed Amendments to the Status of Threatened Species in South Australia 2019 Proposed Amendments to the Status of Threatened Species in South Australia Proposed amendments to the Threatened Species Schedules of the South Australian National Parks and Wildlife Act 1972 In South Australia, threatened plants and animals are listed in schedules of the National Parks and Wildlife Act 1972 (NPW Act), to identify and protect species of conservation concern. The “Threatened Species Schedules” of the NPW Act currently provide for three categories of threat: Endangered (Schedule 7), Vulnerable (Schedule 8) and Rare (Schedule 9), which are designed to reflect the relative risk of extinction in the wild. With the assistance of scientific experts, the Department for Environment and Water assesses the conservation status of South Australia’s plant and animal species. Based on these assessments, the Threatened Species Schedules of the NPW Act are periodically amended to reflect new information, taxonomic changes, and changes in the threat status of species. Public comment is now being sought on recommended changes (new listings, delisting or changes in threat category) for 65 species, to inform proposed amendments to the Threatened Species Schedules. Comments relating to the eligibility of these species for the recommended status classifications and criteria, together with additional information relevant to the assessments, should be sent to [email protected]. Comments will be accepted until 16 August 2019. Suggestions for priority assessments of species not listed here will also be considered for inclusion in the ongoing assessments work plan. Assessments process The South Australian Department for Environment and Water assesses the conservation status of the State’s plant and animal species with considerable assistance from panels of experts on different taxonomic groups. This is an ongoing task that is also dependent upon the continued acquisition of distributional and population data from scientific and community sources. When conducting assessments, DEW assigns species to a threat category as established by the International Union for the Conservation of Nature (IUCN), based on IUCN criteria and guidelines, applied to populations within South Australia. IUCN criteria are summarised in Appendix 1 and more information can be found at: For more information please contact the Department for Environment and Water via email at: [email protected] IUCN (2012). Red List Categories and Criteria: Version 3.1. Second edition. https://portals.iucn.org/library/sites/library/files/documents/RL-2001-001-2nd.pdf. IUCN (2017). Guidelines for Using the IUCN Red List Categories and Criteria: Version 13 http://nc.iucnredlist.org/redlist/content/attachment_files/RedListGuidelines.pdf. For species that also occur outside of South Australia, DEW applies the Guidelines for Application of IUCN Red List Criteria at Regional and National Levels: Version 4.0 (2012) https://www.iucn.org/content/guidelines-application-iucn-red-list-criteria-regional-and-national- levels-version-40. This may lead to an adjustment of the threat category, to reflect the influence of adjacent populations on the risk of extinction from SA. The threatened species schedules of the NPW Act do not currently provide for all of the IUCN categories, as used by other Australian jurisdictions (Fig. 1). Therefore to fit within the current schedules, all species classified as Extinct, Extinct in the Wild, Critically Endangered, and Endangered are listed in Schedule 7 (“Endangered”); and those classified as Vulnerable are listed in Schedule 8 (“Vulnerable”). Plants and animals that are at lesser risk than Vulnerable species, but are still of conservation concern due to their limited distribution, small population size and/or historic declines Schedule 9 (“Rare”). The criteria for assessing species as “Rare” in South Australia are included in Appendix 2. SA NPW Act 1972 categories E V R Endangered Vulnerable Rare EX Extinct EW Extinct in the Wild CR Critically Endangered E Endangered V Vulnerable IUCN IUCN categories NT Near Threatened LC Least Concern Figure 1. Relationship between the threatened species schedule and IUCN categories For more information please contact the Department for Environment and Water via email at: [email protected] Proposed changes The proposed amendments to the Threatened Species Schedules can be found in Appendix 3. The proposed changes include recommendations for: 30 species to be listed for the first time (8 fauna; 22 flora) 15 species to be moved to a higher threat category (8 fauna; 7 flora) 5 species to be moved to a lower threat category (0 fauna; 5 flora); and 15 species to be delisted (6 fauna; 9 flora). The proposed amendments also include administrative changes to reflect updates to the taxonomy and/or nomenclature (naming) of existing listed species (Appendix 4 and 5). This is not a revision of the entire threatened species schedules; further updates will be proposed periodically, as additional species assessments are completed. For more information please contact the Department for Environment and Water via email at: [email protected] Appendix 1. Summary of the five criteria (A-E) used to evaluate if a taxon belongs in a threatened category (Critically Endangered, Endangered or Vulnerable). For more information please contact the Department for Environment and Water via email at: [email protected] Appendix 2. The current criteria for assessing species in South Australia as Rare Criteria a Reduced area of occupancy and/or extent of occurrence: Taxa that have disappeared from >50% of their former area of occupancy and/or extent of occurrence and it is observed, estimated, inferred or suspected that further decline is continuing. b Declined in abundance: Taxa that have experienced a significant decline in abundance in >50% of their former area of occupancy and/or extent of occurrence and it is observed, estimated, inferred or suspected that further decline is continuing. c Small populations: Taxa where it is observed, estimated, inferred or suspected that the total population size numbers <3000 mature individuals and specifying any of the following. i) Resident population ii) Regular visitors to the state (eg. migratory taxa) iii) Irregular visitors to the state (eg. in response to episodic rainfall events) iv) Taxa that are experiencing range extensions into SA, with data for other areas showing that they are increasing in range and abundance. d Restricted extent of occurrence or area of occupancy: Taxa with either of the following: i) extent of occurrence <20,000 km2 ii) area of occupancy <2,000 km2 that is highly fragmented.

  • Disaggregation of Bird Families Listed on Cms Appendix Ii
    Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

  • FINAL REPORT 2019 Canna Reserve
    FINAL REPORT 2019 Canna Reserve This project was supported by NACC NRM and the Shire of Morawa through funding from the Australian Government’s National Landcare Program Canna Reserve BioBlitz 2019 Weaving and wonder in the wilderness! The weather may have been hot and dry, but that didn’t stop everyone having fun and learning about the rich biodiversity and conservation value of the wonderful Canna Reserve during the highly successful 2019 BioBlitz. On the 14 - 15 September 2019, NACC NRM together with support from Department of Biodiversity Conservation and Attractions and the Shire of Morawa, hosted their third BioBlitz at the Canna Reserve in the Shire of Morawa. Fifty professional biologists and citizen scientists attended the event with people travelling from near and far including Morawa, Perenjori, Geraldton and Perth. After an introduction and Acknowledgement of Country from organisers Jessica Stingemore and Jarna Kendle, the BioBlitz kicked off with participants separating into four teams and heading out to explore Canna Reserve with the goal of identifying as many plants, birds, invertebrates, and vertebrates as possible in a 24 hr period. David Knowles of Spineless Wonders led the invertebrate survey with assistance from, OAM recipient Allen Sundholm, Jenny Borger of Jenny Borger Botanical Consultancy led the plant team, BirdLife Midwest member Alice Bishop guided the bird survey team and David Pongracz from Department of Biodiversity Conservation and Attractions ran the vertebrate surveys with assistance from volunteer Corin Desmond. The BioBlitz got off to a great start identifying 80 plant species during the first survey with many more species to come and even a new orchid find for the reserve.

  • Bird Abundances in Primary and Secondary Growths in Papua New Guinea: a Preliminary Assessment
    Mongabay.com Open Access Journal - Tropical Conservation Science Vol.3 (4):373-388, 2010 Research Article Bird abundances in primary and secondary growths in Papua New Guinea: a preliminary assessment Kateřina Tvardíková1 1 Department of Zoology, Faculty of Biological Science, University of South Bohemia, Branišovská 31, CZ- 370 05 České Budějovice. Email: <[email protected] Abstract Papua New Guinea is the third largest remaining area of tropical forest after the Amazon and Congo basins. However, the growing intensity of large-scale slash-and-burn agriculture and logging call for conservation research to assess how local people´s traditional land-use practices result in conservation of local biodiversity, of which a species-rich and diverse component is the avian community. With this in mind, I conducted a preliminary survey of birds in small-scale secondary plots and in adjacent primary forest in Wanang Conservation Area in Papua New Guinea. I used mist-netting, point counts, and transect walks to compare the bird communities of 7-year-old secondary growth, and neighboring primary forest. The preliminary survey lasted 10 days and was conducted during the dry season (July) of 2008. I found no significant differences in summed bird abundances between forest types. However, species richness was higher in primary forest (98 species) than in secondary (78 species). The response of individual feeding guilds was also variable. Two habitats differed mainly in presence of canopy frugivores, which were more abundant (more than 80%) in primary than in secondary forests. A large difference (70%) was found also in understory and mid-story insectivores. Species occurring mainly in secondary forest were Hooded Butcherbird (Cracticus cassicus), Brown Oriole (Oriolus szalayi), and Helmeted Friarbird (Philemon buceroides).

  • Partridges, Quails, Pheasants and Turkeys Phasianidae Vigors, 1825: Zoological Journal 2: 402 – Type Genus Phasianus Linnaeus, 1758
    D .W . .5 / DY a 5D t w[ { wt Ç"" " !W5 í ÇI &'(' / b ù b a L w 5 ! ) " í "* " Ç t+ t " h " * { b ù" t* &)/&0 Order GALLIFORMES: Game Birds and Allies The order of galliform taxa in Checklist Committee (1990) appears to have been based on Peters (1934). Johnsgard (1986) synthesised available data, came up with similar groupings of taxa, and produced a dendrogram indicating that turkeys (Meleagridinae) were the most primitive (outside Cracidae and Megapodiidae), with grouse (Tetraoninae), guineafowl (Numidinae), New World quails (Odontophorinae) and pheasants and kin (Phasianinae) successively more derived. Genetic evidence (DNA-hybridisation data) provided by Sibley & Ahlquist (1990) suggested Odontophorinae were the most basal phasianoids and guineafowl the next most basal group. A basal position of the New World quails among phasianoids has been supported by other genetic data (Kimball et al. 1999, Armstrong et al. 2001). A recent analysis based on morphological characters (Dyke et al. 2003) found support for megapodes as the most basal group in the order, then Cracidae, then Phasianidoidea, and within the latter, Numididae the most basal group. In contrast to the above genetic-based analyses, Dyke et al. (2003) found the Odontophorinae to be the most derived group within the order. A recent analysis using both mitochondrial ND2 and cytochrome-b DNA sequences, however, reinforces the basal position of the Odontophorinae (Pereira & Baker 2006). Here we follow a consensus of the above works and place Odontophorinae basal in the phasianids. Worthy & Holdaway (2002) considered that Cheeseman’s (1891) second-hand record of megapodes from Raoul Island, Kermadec Group, before the 1870 volcanic eruption has veracity.

  • Androcalva Bivillosa
    THREATENED SPECIES SCIENTIFIC COMMITTEE Established under the Environment Protection and Biodiversity Conservation Act 1999 The Minister approved this conservation advice and included this species in the Critically Endangered category, effective from 11/05/2018. Conservation Advice Androcalva bivillosa Summary of assessment Conservation status Androcalva bivillosa has been found to be eligible for listing in the Critically Endangered category as outlined in the attached assessment. Reason for conservation assessment by the Threatened Species Scientific Committee This advice follows assessment of information provided by Western Australia as part of the Common Assessment Method process, to systematically review species that are inconsistently listed under the EPBC Act and relevant state/territory legislation or lists. More information on the Common Assessment Method is available at: http://www.environment.gov.au/biodiversity/threatened/cam The information in this assessment has been compiled by the relevant state/territory government. In adopting this assessment under the EPBC Act, this document forms the Approved Conservation Advice for this species as required under s266B of the EPBC Act. Public consultation Notice of the proposed amendment and a consultation document was made available for public comment for 32 business days between 16 August 2017 and 29 September 2017. Any comments received that were relevant to the survival of the species were considered by the Committee as part of the assessment process. Recovery plan A recovery plan for this species under the EPBC Act is not recommended, because the Approved Conservation Advice provides sufficient direction to implement priority actions and mitigate against key threats. The relevant state/territory may decide to develop a plan under its equivalent legislation.
