Introduction 1 . 1 Reason for this report A Biodiversity Assessment Report and Management Plan is being prepared by Eco Logical Australia Pty Ltd (ELA) for the establishment of a Biobank site on land owned by the Halloran Trust, known as the Wollumboola Biobank Site (herein referred to as the 'Biobank site'). The 1,090 ha Biobank Site is located on the south coast of NSW and is composed of three areas of land connected by Jervis Bay National Park (Figure 1.1). The three areas, known as Culburra Beach, Callala Bay and Kinghorn Point (Figure 1.1), are included in a single biobanking assessment for the proposed Biobank site. The Biobank site and credits generated will be used to partially offset proposed development on land at Culburra Beach to the north and south of the Biobank site and the Halloran Trust Planning Proposal (Figure 1.1). The Callala Bay portion of the Biobank site (301.18 ha) (herein referred to as the 'Callala Bay site') is located to the north of the Callala Bay residential area and is composed of three portions separated by roads (Figure 1.2). The northern portion is bounded by Forest Road to the south, Coonemia Road to the east, and Jervis Bay National Park to the west and north where the site has a boundary with Coonemia Creek. The western portion is bounded by Callala Bay Road to the east, Forest Road to the north, Callala Beach Road to the west and in the south, land owned by the Halloran Trust north of the Callala Bay residential development. The eastern portion is bounded by Currarong Road to the north, Callala Bay Road to the west, Jervis Bay National Park to the east, and in the south, land owned by the Halloran Trust north of the Callala Bay residential development. The Callala Bay area consists of coastal forest and wetland vegetation with the exception of the former tip site to the south of Forest Road. Targeted surveys within the area of the Halloran Trust Planning Proposal and the Callala Bay site first identified the presence of Genoplesium baueri (Bauer's Midge Orchid) in 2006 (BES 2006) with further surveys for this species confirming its continued presence in 2016 (ELA 2017). In accordance with section 6.6.2.5 of the BioBanking Assessment Methodology (OEH 2014; BBAM), this expert report has been prepared to identify whether: "the species [Genoplesium baueri] is likely to be present on the site – in this case the expert report must provide an estimate of the number of individuals or area of habitat to be impacted by the development or the management actions (according to the unit of measurement identified for the species in the Threatened Species Profile Database)." 1 . 2 Qualifications/experience of expert Brian Towle has over 13 years’ experience undertaking flora surveys, and specialises in the identification and ecology of members of the Orchidaceae. During this time, he has undertaken a range of projects including expert reports for threatened orchid species, targeted surveys, vegetation monitoring programs, BioBanking agreements, applications for Biodiversity certification, large scale vegetation mapping/modelling projects, and a range of impact assessments. Brian has worked across a range of ecosystems across NSW, and in parts of QLD (Bowen Basin), from the coast to the far western plains including arid woodlands, shrublands and grasslands, wet sclerophyll forests, rainforests and coastal swamps. This 1 Expert Report for Genoplesium baueri Lake Wollumboola Biobank Site experience has exposed him to a diversity of flora and fauna distributed across these ecosystems. In relation to threatened orchids, Brian has undertaken research into the ecology of native orchids and in particular species of Genoplesium (sensu lato) co-authoring publications within peer-reviewed journals: • Bower, C., Towle, B. and Bickel, D. (2015). Reproductive success and pollination of the Tuncurry Midge Orchid (Genoplesium littorale) (Orchidaceae) by Chloropid Flies. Telopea 18:43-55. • Bernhardt, P., Edens-Meier, R., Grimm, W., Ren, Z. and Towle, B. (2017). Global collaborative research on the pollination biology of rare and threatened orchid species (Orchidaceae). Annals of the Missouri Botanical Gardens. Brian has prepared expert reports assessing the habitat for threatened orchid species, Pterostylis sp. Botany Bay and Thelymitra atronitida. He has also undertaken targeted surveys for and mapping the habitat of numerous threatened orchids species including: • Caladenia arenaria (syn. Arachnorchis arenaria, Spider Orchid) • Microtis angusii • Pterostylis saxicola (syn. Oligochaetochilus saxicola, Sydney Plains Greenhood) • Pterostylis ventricosa (syn.

  • NSW Vagrant Bird Review
    an atlas of the birds of new south wales and the australian capital territory Vagrant Species Ian A.W. McAllan & David J. James The species listed here are those that have been found on very few occasions (usually less than 20 times) in NSW and the ACT, and are not known to have bred here. Species that have been recorded breeding in NSW are included in the Species Accounts sections of the three volumes, even if they have been recorded in the Atlas area less than 20 times. In determining the number of records of a species, when several birds are recorded in a short period together, or whether alive or dead, these are here referred to as a ‘set’ of records. The cut-off date for vagrant records and reports is 31 December 2019. As with the rest of the Atlas, the area covered in this account includes marine waters east from the NSW coast to 160°E. This is approximately 865 km east of the coast at its widest extent in the south of the State. The New South Wales-Queensland border lies at about 28°08’S at the coast, following the centre of Border Street through Coolangatta and Tweed Heads to Point Danger (Anon. 2001a). This means that the Britannia Seamounts, where many rare seabirds have been recorded on extended pelagic trips from Southport, Queensland, are east of the NSW coast and therefore in NSW and the Atlas area. Conversely, the lookout at Point Danger is to the north of the actual Point and in Queensland but looks over both NSW and Queensland marine waters.

  • Ecological Studies on Illawarha Lake
    ECOLOGICAL STUDIES ON ILLAWARHA LAKE WITH SPECIAL REFERENCE TO Zostera capricorni Ascherson. By Malcolm McD. Harris, B.A. ( Univ. of New England, Armidale ) A thesis submitted in fulfilment of the requirements for the degree of Master of Science of the University of New South Wales. School of Botany, University of New South Wales. January, 1977 UNIVERSITY OF N.S.W. 19851 16 SEP. 77 LIBRARY THIS IS TO CERTIFY that the work described in this thesis has not been submitted for a higher degree at any other university or institution. (iii) SUMMARY This thesis describes aspects of the ecology of Illawarra Lake, with special reference to the biology of the seagrass, Zostera capricomi Aschers. Observations were made from the air, from power boats, by wading and by SCUBA diving, over the period 1972 - 1976. Use has also been made of aerial photographs. The environmental factors studied include both sediment characteristics and water quality. Correlation coefficients have been calculated and used in the assessment of the functional relationships between the parameters examined. Reference has been made to corroborative evidence from a number of sources. The relationship between the distribution and biomass of the benthic flora of Illawarra Lake, and the selected environmental parameters, is examined. Seven other coastal saline lagoons were observed so that observations made and the conclusions drawn for Illawarra Lake, could be seen in the wider context. Long term observations and analyses have been made of the morphology, growth and flowering cycles of Z. capricomi. Evidence is presented showing some diagnostic features,used in published accounts to distinguish between Z.

  • Rare Or Threatened Vascular Plant Species of Wollemi National Park, Central Eastern New South Wales
    Rare or threatened vascular plant species of Wollemi National Park, central eastern New South Wales. Stephen A.J. Bell Eastcoast Flora Survey PO Box 216 Kotara Fair, NSW 2289, AUSTRALIA Abstract: Wollemi National Park (c. 32o 20’– 33o 30’S, 150o– 151oE), approximately 100 km north-west of Sydney, conserves over 500 000 ha of the Triassic sandstone environments of the Central Coast and Tablelands of New South Wales, and occupies approximately 25% of the Sydney Basin biogeographical region. 94 taxa of conservation signiicance have been recorded and Wollemi is recognised as an important reservoir of rare and uncommon plant taxa, conserving more than 20% of all listed threatened species for the Central Coast, Central Tablelands and Central Western Slopes botanical divisions. For a land area occupying only 0.05% of these divisions, Wollemi is of paramount importance in regional conservation. Surveys within Wollemi National Park over the last decade have recorded several new populations of signiicant vascular plant species, including some sizeable range extensions. This paper summarises the current status of all rare or threatened taxa, describes habitat and associated species for many of these and proposes IUCN (2001) codes for all, as well as suggesting revisions to current conservation risk codes for some species. For Wollemi National Park 37 species are currently listed as Endangered (15 species) or Vulnerable (22 species) under the New South Wales Threatened Species Conservation Act 1995. An additional 50 species are currently listed as nationally rare under the Briggs and Leigh (1996) classiication, or have been suggested as such by various workers. Seven species are awaiting further taxonomic investigation, including Eucalyptus sp.
