ISBN 0 7313 6129 6 National Parks and Wildlife Service Recovery Planning Program Lord Howe Placostylus Placostylus bivaricosus Recovery Plan Foreword The conservation of threatened species, populations and ecological communities is crucial for the maintenance of this State’s unique biodiversity. In NSW, the Threatened Species Conservation Act 1995 (TSC Act) provides the framework to conserve and recover threatened species, populations and ecological communities through the preparation and implementation of recovery plans. The preparation and implementation of recovery plans is identified by both the National Strategy for the Conservation of Australia’s Biological Diversity and the draft NSW Biodiversity Strategy as a key strategy for the conservation of threatened flora and fauna. The object of a recovery plan is to document the research and management actions required to promote the recovery of a threatened species, population or ecological community and to ensure its ongoing viability in nature. The TSC Act requires that the Director-General of National Parks and Wildlife prepare recovery plans for all species, populations and ecological communities listed as endangered or vulnerable on the TSC Act schedules. The TSC Act includes specific requirements for both the matters to be addressed by recovery plans and the process for preparing recovery plans. This plan satisfies these provisions. This plan describes our current understanding of the threatened Lord Howe Placostylus Placostylus bivaricosus, documents the research and management actions undertaken to date, and identifies the actions required and parties responsible to maximise the opportunity for the species’ ongoing viability in the wild.

  • Husbandry of the Carnivorous Land Snail, Powelliphanta Augusta (Gastropoda: Pulmonata: Rhytdidae)
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by ResearchArchive at Victoria University of Wellington Husbandry of the Carnivorous Land Snail, Powelliphanta augusta (Gastropoda: Pulmonata: Rhytdidae) By Thomas Edward Allan A thesis submitted to the Victoria University of Wellington in fulfillment of the requirements for the degree of Master of Science in Ecological Restoration Victoria University of Wellington 2010 1 Abstract Key aspects of the captive husbandry of Powelliphanta augusta, a newly-described New Zealand land snail are investigated: how they should be managed and fed to provide individuals for release, and how a long-term captive population can be maintained as an insurance against extinction in the wild. This project arises from almost all members of this species having been brought into captivity due to their displacement in the wild by an opencast coalmine. Powelliphanta (F: Rhytididae) is a genus of endemic carnivorous snails, which includes 10 species, 27 subspecies and numerous undescribed taxa. As well as its diversity, Powelliphanta is renowned for the large size of its members (up to 90mm diameter) and their attractively-patterned shells. Most taxa are threatened due to habitat loss and predation by introduced mammalian predators. The study commences with a literature review to refine husbandry methods and to assess requirements for captive breeding of snails. From this review investigations are made into stocking densities, substrate, reproductive biology, body condition and growth of the P. augusta captive population. To determine an appropriate stocking density for P. augusta groups of six snails were kept at two densities; with either 720cm2, or 1440cm2 per group.

  • Direct Impacts of Seabird Predators on Island Biota Other Than Seabirds D.R
    4 Direct Impacts of Seabird Predators on Island Biota other than Seabirds D.R. Drake, T.W. Bodey, J.e. Russell, D.R. Towns, M. Nogales, and L. Ruffino Introduction "... I have not found a single instance .. , ofa terrestrial mammal inhabiting an island situated above 300 miles from a continent or great continental island; and many islands situated at a much less distance are equally barren:' (DARWIN 1859) "He who admits the doctrine of special creation ofeach species, will have to admit, that a sufficient number ofthe best adapted plants and animals have not been created on oceanic islands; for man has unintentionally stocked them from various sources far more fully and perfectly than has nature:' (DARWIN 1859) Since Darwin's time, islands have been celebrated for having highly endemic floras and faunas, in which certain taxonomic groups are typically overrepresented or underrepresented relative to their abundance on the nearest continents (Darwin 1859, Wallace 1911, Carlquist 1974, Whittaker and Fermindez-Palacios 2007). Sadly, island endemics in many taxonomic groups have suffered a disproportionately large number ofthe world's extinctions, and introduced mammals have frequently been implicated in their decline and disappearance (Vitousek 1988, Flannery and Schouten 2001, Drake et al. 2002, Courchamp et al. 2003, Steadman 2006). Of the many mammalian predators introduced to islands, those having the most important impact on seabirds are cats, foxes, pigs, rats, mice, and, to a lesser extent, dogs and mongooses (discussed extensively in Chapter 3). These predators can be divided into two groups: superpredators and mesopredators. Superpredators (e.g., cats and foxes) are carnivores, relatively large, and able to consume all life stages oftheir prey (including other, smaller predator species).

  • Placostylus Bivaricosus Breeding Project Final Report
    Final Report Placostylus bivaricosus Breeding Project 13 December 2010 Ian Hutton PO Box 157 Lord Howe Island NSW 2898 Introduction to Placostylus bivaricosus The genus Placostylus is a group of large ground dwelling gastropods with a disjunct distribution in the Southwest Pacific from the Solomon Islands, Fiji and New Caledonia, to Lord Howe Island and the northern extremity of New Zealand. Three recent subspecies of the Lord Howe Island Placostylus are recognized. P. bivaricosus bivaricosus from the settlement area; P. bivaricosus cuniculinsulae from Blackburn Island (now presumed extinct) and P. bivaricosus etheridgeri from Little Slope considered likely to be extinct but there is a chance it may survive in isolated populations based on recent identification of hatchling snails from leaf litter collected on Little and Big Slopes in the 1970’s. The extant Lord Howe land snail Placostylus bivaricosus bivaricosus (from now on called Placostylus bivaricosus) is a large terrestrial snail found only on Lord Howe Island. This snail has a brown, pointed shell up to 7cm long and 2 cm in diameter. It is most closely related to New Zealand Placostylus species. Its status has declined from common to endangered. Historical accounts and fossil evidence indicate that the LHI Placostylus bivaricosus was formerly widespread and abundant on parts the island. The decline was first noted in the 1940’s and the species is now listed as critically endangered on the 2000 IUCN Red List of Threatened Species. The causes for decline of the LHI Placostylus are likely to include habitat clearing and modification, predation and habitat disturbance by introduced fauna (rats, Blackbirds and Song thrushes) and possibly herbicide and pesticide use.

  • Proceedings of the United States National Museum
    a Proceedings of the United States National Museum SMITHSONIAN INSTITUTION • WASHINGTON, D.C. Volume 121 1967 Number 3579 VALID ZOOLOGICAL NAMES OF THE PORTLAND CATALOGUE By Harald a. Rehder Research Curator, Division of Mollusks Introduction An outstanding patroness of the arts and sciences in eighteenth- century England was Lady Margaret Cavendish Bentinck, Duchess of Portland, wife of William, Second Duke of Portland. At Bulstrode in Buckinghamshire, magnificent summer residence of the Dukes of Portland, and in her London house in Whitehall, Lady Margaret— widow for the last 23 years of her life— entertained gentlemen in- terested in her extensive collection of natural history and objets d'art. Among these visitors were Sir Joseph Banks and Daniel Solander, pupil of Linnaeus. As her own particular interest was in conchology, she received from both of these men many specimens of shells gathered on Captain Cook's voyages. Apparently Solander spent considerable time working on the conchological collection, for his manuscript on descriptions of new shells was based largely on the "Portland Museum." When Lady Margaret died in 1785, her "Museum" was sold at auction. The task of preparing the collection for sale and compiling the sales catalogue fell to the Reverend John Lightfoot (1735-1788). For many years librarian and chaplain to the Duchess and scientif- 1 2 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 121 ically inclined with a special leaning toward botany and conchology, he was well acquainted with the collection. It is not surprising he went to considerable trouble to give names and figure references to so many of the mollusks and other invertebrates that he listed.

  • Integrated Conservation Approach for the Australian Land Snail Genus Bothriembryon Pilsbry, 1894: Curation, Taxonomy and Palaeontology
    Integrated conservation approach for the Australian land snail genus Bothriembryon Pilsbry, 1894: curation, taxonomy and palaeontology Corey Whisson This thesis is presented for the Master of Philosophy 2019 Murdoch University, Perth, Western Australia DECLARATION I declare that this thesis is my own original account of my research and contains as its main content, work which has not previously been submitted for a degree at any tertiary education institution and as author, I reserve the right of copyright under the Copyright Act 1968, Commonwealth of Australia. …………………………………………………………… Corey Whisson i "Probably the most intriguing land shells in Australia are the bulimoid forms inhabiting the south-west corner. A large number of species and races has developed, and probably only a tithe has been described. It is unfortunate these have not yet been studied by anyone conversant with local conditions, and it is certain that they will provide future students with much research. No more exciting subject could be chosen by the student, but the unravelling of the many problems will necessitate much investigation." Mr Tom Iredale (cited in Iredale, 1939) ii Abstract Native land snails are important to ecosystems given their role in the decomposition process through herbivorous feeding of primarily decaying plant matter; calcium recycling and soil nitrification, and as a food source for larger predators. They also serve as a valuable bio-indicator group, especially in Western Australia where they are critical to Environmental Impact Assessments surveys. One conspicuous genus of native land snail found in Western Australia is Bothriembryon Pilsbry, 1894, a Gondwanan group endemic to the southern half of Australia and most diverse in the south-west of Western Australia.
