Appendix B Flora Survey Effort and Results APPENDIX B FLORA SURVEY EFFORT AND RESULTS October 2016 Prepared by Anderson Environment and Planning The Flora Survey Effort (FLSE) for the Biobanking Assessment Report has been guided by the following: The predict threatened flora species from within the Biobanking Credit Calculator; The Threatened Species Survey and Assessment Guidelines for developments and activities (working draft), NSW Department of Environment and Conservation (2004); The NSW Threatened Species Profile Database; and Previous flora survey results from the site. The Biobanking Calculator identified the following species as requiring survey for the proposed development: Melaleuca biconvexa (Biconvex Paperbark); Tetratheca juncea (Black-eyed Susan); Melaleuca groveana (Groves Paperbark); Cryptostylis hunteriana (Leafless Tongue Orchid); Corybas dowlingii (Red Helmet Orchid); Diuris praecox (Rough Double Tail); Grevillea parviflora (Small-flower Grevillea); Persicaria elatior (Tall Knotweed); Cyanchum elegans (White-flowered Wax Plant); Eucalyptus parramattensis subsp. parramattensis population, Wyong and Lake Macquarie local government areas. Following targeted and seasonal survey for the above species only Melaleuca biconvexa was recorded adjacent to the development site and all individuals specimens will be retained following development.

At the request of the Office of Environment and Heritage (OEH) additional fieldwork has been undertaken to provide more contemporary data for the development site. 1.2 Site Survey Rationale The FLSE for the Biobanking Assessment was guided by the following: Previous threatened species records for the development site and adjacent lands; The predict threatened species from within the Biobanking Credit Calculator; and The Threatened Species Survey and Assessment Guidelines for developments and activities (working draft), NSW Department of Environment and Conservation (2004). From the above the following threatened flora species required seasonal survey. The remaining threatened species were able to be surveyed at any time of year: Tetratheca juncea (July to December); Cryptostylis hunteriana (November to February); Corybas dowlingii (June to August); Diuris praecox (July to August); Persicaria elatior (December to May); To adequately provide contemporary survey data for the above species two seasonal surveys were undertaken in February and August. ; Prepared by Anderson Environment and Planning 2.0 Field Survey 2.1 Previous Assessments The following is a summary of the field survey undertaken on the site prior to the current assessment.

Pap. Proc. R. Soc. Tasm. 133(1): 103-113. ISSN 0080-4703. School of Geography and Environmental Studies, University ofTasmania, GPO Box 252-78, Hobart, Tasmania, Australia 7001. The Huntingfield area has a varied vegetation, including substantial areas ofEucalyptus amygdalina heathy woodland, heath, buttongrass moorland and E. amygdalina shrubbyforest, with smaller areas ofwetland, grassland and E. ovata shrubbyforest. Six floristic communities are described for the area. Two hundred and one native vascular plant taxa, 26 moss species and ten liverworts are known from the area, which is particularly rich in orchids, two ofwhich are rare in Tasmania. Four other plant species are known to be rare and/or unreserved inTasmania. Sixty-four exotic plantspecies have been observed in the area, most ofwhich do not threaten the native biodiversity. However, a group offire-adapted shrubs are potentially serious invaders. Management problems in the area include the maintenance ofopen areas, weed invasion, pathogen invasion, introduced animals, fire, mechanised recreation, drainage from houses and roads, rubbish dumping and the gathering offirewood, sand and plants. Key Words: flora, forest, heath, Huntingfield, management, Tasmania, vegetation, wetland, woodland. INTRODUCTION species with the most cover in the shrub stratum (dominant species) was noted.

Ecological influences in the biogeography of the aus- tral sedges. MSc dissertation. University of Cape Town. Cape Town. February 2016. supervisors: A. Muthama Muasya G. Anthony Verboom ABSTRACT The biogeographic history of a species is a result of both stochastic processes such as dispersal and habitat filters that determine where a population with a given set of biological requirements can become es- tablished. In this dissertation, I examine the geographical and ecolog- ical distribution of the sedge tribe Schoeneae in conjunction with its inferred speciation history in order to determine the pattern of disper- sal and the environmental factors that have influenced establishment. The biogeographic reconstruction indicates numerous transoceanic dispersal events consistent with random diffusion from an Australian point of origin, but with a bias towards habitats with vegetation type and moisture regime similar to the ancestral conditions of the given subgroup (open and dry habitats in the majority of cases). The global distribution of the tribe also suggests a preference for low-nutrient soils, which I investigate at the local (microhabitat) scale by contrast- ing the distributions of the tribes Schoeneae and Cypereae on the Cape Peninsula along soil fertility axes.

  • Glossy Black-Cockatoo
    Glossy black-cockatoo Calyptorynchus lathami Yuyang (Wiradjuri) Photo: Chris Tzaros The glossy black-cockatoo may be confused with the red-tailed black-cockatoo, but it has more brownish-black plumage on the head, neck and underbody. Their body plumage is more dull black and not uniformly glossy. Also, adult females have much more yellow on the head and lack the yellow spotting on the body that red-tailed black-cockatoos have. Description Size: The glossy black-cockatoo of the Riverina is a medium-sized cockatoo. Plumage: Glossy black-cockatoos are generally black but have a blackish-brown head, neck and underparts with red or yellowish-red panels in the tail. Adult females have patches of yellow feathering on head and neck. Bill: They have a broad bulbous bill that is used for tearing apart the seed cones of sheoaks, their primary food source, and to create hollows in old trees for nesting. Call: Noisy squawks or creaky calls; wheezy ‘airr-riick’, ‘kee-aiirrk’, ‘airrek’. Quieter and less raucous than other black-cockatoos. Photo: Chris Tzaros Habitat Glossy black-cockatoos can be found in open forest and woodlands of the coast and the Great Dividing Range where stands of sheoak occur, such as black sheoak (Allocasuarina littoralis) and forest sheoak (A. torulosa). Inland, they feed on drooping sheoak (A. verticillata), broombush sheoak (A. diminuta) and mallee sheoak (A. gymnanthera). Belah (Casuarina cristata) is also utilised and may be a critical food source for some populations. The Riverina population is largely restricted to hills and low ridges where suitable stands of its food plant, the drooping sheoak, remain.

  • 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.
