The assessment was conducted in three stages. Firstly, a desktop analysis was performed to identify potential Terrestrial GDEs. A field survey was then performed to verify these potential Terrestrial GDEs and collect data to assess their condition and detect other ecological values.

Female solitary bees create unique nests which they pack with a pollen / nectar food mix then lay their eggs. In spring the next generation of bees emerge. Creating solitary bee Habitat in the form of Bee Homes has become popular in recent years with some large and impressive structures installed everywhere from Paris to Woodford and backyard versions are sold in Bunnings and Aldi. However, there are significant risks associated: • large numbers of bees nesting in close proximity become targets for parasitic insects and mites; and • mass produced commercial bee home are typically too shallow for a balanced production of female and male bees. (References Appendix B - Purrinton and Nurturing Nature) Interestingly female eggs are laid first in the nest hollow with male egg laid closer to the front. Male bees hatch first then wait around till females emerge a few days later. Male larva being close to the entry are also more vulnerable to attack by parasitic wasps, so act as extra protection for the more important females.

  • Diversity in Host Preference of Rotylenchus Spp. Y.S
    International Journal of Science, Environment ISSN 2278-3687 (O) and Technology, Vol. 7, No 5, 2018, 1786 – 1793 2277-663X (P) DIVERSITY IN HOST PREFERENCE OF ROTYLENCHUS SPP. Y.S. Rathore Principal Scientist (Retd.), Indian Institute of Pulses Research, Kanpur -208024 (U.P.) E-mail: [email protected] Abstract: Species of the genus Rotylenchus are ecto- or semi-endo parasites and feed on roots of their host plants. In the study it was found that 50% species of Rotylenchus were monophagous and mostly on plants in the clade Rosids followed by monocots, Asterids and gymnosperms. In general, Rosids and Asterids combined parasitized more than 50% host species followed by monocots. Though food preference was species specific but by and large woody plants were preferred from very primitive families like Magnoliaceae and Lauraceae to representatives of advanced families. Woody plants like pines and others made a substantial contribution in the host range of Rotylenchus. Maximum number of Rotylenchus species harboured plants in families Poaceae (monocots), Rosaceae (Rosids) and Oleaceae (Asterids) followed by Fabaceae, Fagaceae, Asteraceae and Pinaceae. It is, therefore, suggested that agricultural crops should be grown far away from wild vegetation and forest plantations. Keywords: Rotylenchus, Magnoliids, Rosids, Asterids, Gymnosperms, Host preference. INTRODUCTION Species of the genus Rotylenchus (Nematoda: Haplolaimidae) are migratory ectoparasites and browse on the surface of roots. The damage caused by them is usually limited to necrosis of penetrated cells (1). However, species with longer stylet penetrate to tissues more deeply and killing more cells and called as semi-endoparasites (2,3). The genus contains 97 nominal species which parasitize on a wide range of wild and cultivated plants worldwide (3).

  • Conservation Advice for the Karst Springs and Associated Alkaline Fens of the Naracoorte Coastal Plain Bioregion
    The Threatened Species Scientific Committee provided their advice to the Minister on 31 July 2020. The Minister approved this Conservation Advice on 3 December 2020 and agreed that no recovery plan is required at this time. Conservation Advice1 for the Karst springs and associated alkaline fens of the Naracoorte Coastal Plain Bioregion This document combines the approved conservation advice and listing assessment for the threatened ecological community. It provides a foundation for conservation action and further planning. Karst springs and alkaline fens, Ewen Ponds © Copyright, Anthony Hoffman Conservation Status The Karst springs and associated alkaline fens of the Naracoorte Coastal Bioregion is listed in the Endangered category of the threatened ecological communities list under the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act). The ecological community was assessed by the Threatened Species Scientific Committee, who found it to be eligible for listing as Endangered and recommended that a recovery plan is not required at this time. The Committee’s assessment and recommendations are at Section 6. The Committee’s assessment of the eligibility against each of the listing criteria is: Criterion 1: Vulnerable Criterion 2: Endangered Criterion 3: Insufficient data Criterion 4: Endangered Criterion 5: Insufficient data Criterion 6: Insufficient data The main factors that make the threatened ecological community eligible for listing in the Endangered category are its historic losses to drainage, clearing and resulting fragmentation, and ongoing threats to its integrity and function, particularly from hydrological changes. The Karst springs and associated alkaline fens of the Naracoorte Coastal Plain Bioregion occurs within country (the traditional lands) of the Boandik and the Gunditjmara peoples.

  • Native Plants of Sydney Harbour National Park: Historical Records and Species Lists, and Their Value for Conservation Monitoring
    Native plants of Sydney Harbour National Park: historical records and species lists, and their value for conservation monitoring Doug Benson National Herbarium of New South Wales, Royal Botanic Gardens, Mrs Macquaries Rd, Sydney 2000 AUSTRALIA [email protected] Abstract: Sydney Harbour National Park (lat 33° 53’S; long 151° 13’E), protects significant vegetation on the harbour foreshores close to Sydney City CBD; its floristic abundance and landscape beauty has been acknowledged since the writings of the First Fleet in 1788. Surprisingly, although historical plant collections were made as early as1802, and localised surveys have listed species for parts of the Park since the 1960s, a detailed survey of the flora of whole Park is still needed. This paper provides the first definitive list of the c.400 native flora species for Sydney Harbour National Park (total area 390 ha) showing occurrence on the seven terrestrial sub-regions or precincts (North Head, South Head, Dobroyd Head, Middle Head, Chowder Head, Bradleys Head and Nielsen Park). The list is based on historical species lists, records from the NSW Office of Environment and Heritage (formerly Dept of Environment, Climate Change and Water) Atlas, National Herbarium of New South Wales specimen details, and some additional fieldwork. 131 species have only been recorded from a single precinct site and many are not substantiated with a recent herbarium specimen (though there are historical specimens from the general area for many). Species reported in the sources but for which no current or historic specimen exists are listed separately as being of questionable/non-local status.
