Appendix Appendix 1: Concept Plan Appendix 2: Flora Species List 3 1 INTRODUCTION 1.1 Background Eco Logic Environmental Services (EcoLogic) was commissioned by Calibre Consulting to undertake a flora and vegetation assessment of Lots 14, 28 and 29 Jeffrey Road, Glen Iris to provide background information for the proposed development of the property (Appendix 1- Concept Plan). A flora and vegetation assessment of Lot 29 Jeffrey Road, Glen Iris has previously been undertaken by EcoLogic in 2015 and this information has been incorporated into this report. The flora and vegetation on Lot 29 and Lot 28 have been assessed and mapped as part of this report. The assessment of Lot 14 was undertaken in June 2018 with the results also incorporated into this report. 1.2 Scope of Works The Flora and Vegetation Assessment of the site included the following: • Survey Methodology, including database searches and limitations; • Provide a list of native and non-native plant species recorded from representative vegetation types, as well as a thorough site walkover to record all additional species. Non-permanent 10m x10m quadrats may also be sampled in vegetation in Good or better condition; • A list of significant species recorded on the Department of Biodiversity, Conservation and Attractions (DBCA) NatureMap database and the EPBC Act Protected Matters Report within the vicinity of the study area; • The location of any Threatened species and Priority species and Threatened Ecological Communities and Priority Ecological Communities identified on site will be recorded using a handheld Global Positioning System (GPS); • A description and mapping of the vegetation types and vegetation condition (using the Bush Forever condition rating); • Provide recommendations on the conservation significance of flora and vegetation listed under the Wildlife Conservation Act 1950 and the Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act 1999). Discussion on any possible constraints (related to flora) to the development. • Liaison with the client on recommended management measures to protect any potential conservation significant flora at the site. The detailed flora and vegetation assessment was undertaken in accordance with EPA Technical Guidance- Flora and Vegetation Survey (EPA, 2016). 2. FLORA AND VEGETATION SURVEY METHODOLOGY 2.1 Survey Methodology The flora and vegetation assessment of Lot 28 and 29 Jeffrey Road, Glen Iris was undertaken by Ms Kay Lehman an experienced botanist from Eco Logic Environmental Services on 11 February 2018. A total of 3 hours was spent undertaking the flora and vegetation survey which is considered an adequate time given the area and degraded 4 nature of remnant vegetation within the study area. The flora and vegetation assessment of Lot 14 was undertaken on 30 June 2018. The flora and vegetation assessment involved compiling information from DBCA NatureMap database and EPBC Act Protected Matters Report and undertaking a targeted survey including thoroughly traversing the study area on foot to record all plant species present at the time of the survey. The vegetation types were initially delineated using recent serial photography supplemented by the on-ground survey to record vegetation community types, condition and map vegetation community types. The detailed flora and vegetation assessment was undertaken in accordance with EPA Technical Guidance- Flora and Vegetation Survey (EPA, 2016). The DBCA Nature Map and EPBC Act Protected Matters Report species list of conservation significant flora located in the vicinity of the study areas was used as a guide for the field assessment. Species on the DBCA NatureMap database lists were reviewed on DBCA’s on- line Florabase system (DBCA, 2018a) and through researching regional botanical texts prior to undertaking the field assessment (Wheeler et al., 2002). The timing of the survey in summer (February and June 2018) was not considered optimal for the identification of the some of threatened and/or priority listed flora potentially occurring in the area. However, given the degraded vegetation condition across the study area, it is considered unlikely that threatened and/or priority flora species would be present. Common species that were well known to the survey botanist were identified in the field, while specimens of all other species were collected, assigned a unique identification number to facilitate tracking and pressed that day. Plant specimens collected were then identified using local and regional keys and the DBCA Florabase. A handheld GPS was used to record the location of species of conservation significance and colour photographs were taken of each vegetation type. The following information was collected from each vegetation type: • Habitat • Soil • Rock Type • Vegetation Type and Structure • Vegetation Condition • Species (height) 2.1.1 Vegetation Description Vegetation types were described and mapped according to the structure and species composition of the dominant stratum using the system adapted from Muir (1977) and Aplin (1979). Vegetation descriptions are presented in Table 1 below. 5 Table 1: Vegetation Structural Classes Canopy Cover Stratum (adapted from Muir, 1977 and Aplin, 1979) 70-100% 30-70% 10-30% 2-10% <2% Trees over Tall Closed Tall Open Tall Tall Open Scattered Tall 30m Forest Forest Woodland Woodland Trees Trees Open Scattered Closed Forest Open Forest Woodland 10-30m Woodland Trees Trees Low Closed Low Open Low Low Open Scattered Low under 10m Forest Forest Woodland Woodland Trees Shrubs Tall Closed Tall Open Tall Tall Open Scattered Tall over 2m Scrub Scrub Shrubland Shrubland Trees Shrubs Open Scattered Low Closed Heath Open Heath Shrubland 1-2m Shrubland Shrubs Shrubs Low Closed Low Open Low Low Open Scattered Low under 1m Heath Heath Shrubland Shrubland Shrubs Closed Open Very Open Scattered Grasses Grassland Grassland Grassland Grassland Grasses Closed Open Very Open Herbs and Sedgeland/ Scattered Sedgeland/ Sedgeland/ Sedgeland/ Sedges Herbland Sedges/Herbs Herbland Herbland Herbland 2.1.2 Vegetation Condition Vegetation condition was assessed using the condition rating scale (adapted from Keighery 1994 and Trudgen 1988). Vegetation condition is presented in Table 2 below. 6 Table 2: Vegetation Condition Ratings Pristine or nearly so, no obvious signs of disturbance or damage caused Pristine by human activities since European settlement.

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.

Email: [email protected] Abstract. Fire is an important ecological disturbance in vegetated ecosystems across the globe, and also has considerable impacts on human infrastructure. Vegetation flammability is a key bottom-up control on fire regimes and on the nature of individual fires. Although New Zealand (NZ) historically had low fire frequencies, anthropogenic fires have considerably impacted indigenous vegetation as humans used fire extensively to clear forests. Few studies of vegetation flammability have been undertaken in NZ and only one has compared the flammability of indigenous plants; this was a qualitative assessment derived from expert opinion. We addressed this knowledge gap by measuring the flammability of terminal shoots from a range of trees and shrubs found in NZ.

    American Journal of Botany 96(5): 1041–1049. 2009. G LOBAL CHLOROPLAST PHYLOGENY AND BIOGEOGRAPHY OF BRACKEN ( PTERIDIUM ; DENNSTAEDTIACEAE) 1 Joshua P. Der, 2,4 John A. Thomson, 3 Jeran K. Stratford, 2,5 and Paul G. Wolf 2 2 Department of Biology, Utah State University, 5305 Old Main Hill, Logan, Utah 84322 USA; and 3 National Herbarium of New South Wales, Botanic Gardens Trust, Mrs Macquaries Road, Sydney, NSW 2000, Australia Bracken ferns (genus Pteridium ) represent an ancient species complex with a natural worldwide distribution. Pteridium has historically been treated as comprising a single species, but recent treatments have recognized several related species. Phenotypic plasticity, geographically structured morphological variation, and geographically biased sampling have all contributed to taxo- nomic confusion in the genus. We sampled bracken specimens worldwide and used variable regions of the chloroplast genome to investigate phylogeography and reticulate evolution within the genus. Our results distinguish two major clades within Pteridium , a primarily northern hemisphere Laurasian/African clade, which includes all taxa currently assigned to P. aquilinum , and a primar- ily southern hemisphere Austral/South American clade, which includes P. esculentum and P. arachnoideum . All European acces- sions of P. aquilinum subsp. aquilinum appear in a monophyletic group and are nested within a clade containing the African P. aquilinum taxa ( P. aquilinum subsp. capense and P. aquilinum subsp. centrali-africanum ). Our results allow us to hypothesize the maternal progenitors of two allotetraploid bracken species, P. caudatum and P. semihastatum . We also discuss the biogeography of bracken in the context of the chloroplast phylogeny. Our study is one of the fi rst to take a worldwide perspective in addressing variation in a broadly distributed species complex.

We discuss the landscapes of Botany Bay and particularly of the historic landing place at Kurnell (lat 34˚ 00’ S, long 151˚ 13’ E) (about 16 km south of central Sydney), as described in the journals of Lieutenant James Cook and Joseph Banks on the Endeavour voyage in 1770. We list 132 plant species that were collected at Botany Bay by Banks and Daniel Solander, the first scientific collections of Australian flora. The list is based on a critical assessment of unpublished lists compiled by authors who had access to the collection of the British Museum (now Natural History Museum), together with species from material at National Herbarium of New South Wales that has not been previously available. The list includes Bidens pilosa which has been previously regarded as an introduced species. In 1770 the Europeans set foot on Aboriginal land of the Dharawal people. Since that time the landscape has been altered in response to a succession of different land-uses; farming and grazing, commemorative tree planting, parkland planting, and pleasure ground and tourist visitation.

  • Flora of Stockton/Port Hunter Sandy Foreshores
    Flora of the Stockton and Port Hunter sandy foreshores with comments on fifteen notable introduced species. Petrus C. Heyligers CSIRO Sustainable Ecosystems, Queensland Biosciences Precinct, 306 Carmody Road, St. Lucia, Queensland 4067, AUSTRALIA. [email protected] Abstract: Between 1993 and 2005 I investigated the introduced plant species on the Newcastle foreshores at Stockton and Macquaries Pier (lat 32º 56’ S, long 151º 47’ E). At North Stockton in a rehabilitated area, cleared of *Chrysanthemoides monilifera subsp. rotundata, and planted with *Ammophila arenaria interspersed with native shrubs, mainly Acacia longifolia subsp. sophorae and Leptospermum laevigatum, is a rich lora of introduced species of which *Panicum racemosum and *Cyperus conglomeratus have gradually become dominant in the groundcover. Notwithstanding continuing maintenance, *Chrysanthemoides monilifera subsp. rotundata has re-established among the native shrubs, and together with Acacia longifolia subsp. sophorae, is important in sand stabilisation along the seaward edge of the dune terrace. The foredune of Little Park Beach, just inside the Northern Breakwater, is dominated by Spinifex sericeus and backed by Acacia longifolia subsp. sophorae-*Chrysanthemoides monilifera subsp. rotundata shrubbery. In places the shrubbery has given way to introduced species such as *Oenothera drummondii, *Tetragonia decumbens and especially *Heterotheca grandilora. At Macquaries Pier *Chrysanthemoides monilifera subsp. rotundata forms an almost continuous fringe between the rocks that protect the pier against heavy southerlies. However, its presence on adjacent Nobbys Beach is localised and the general aspect of this beach is no different from any other along the coast as it is dominated by Spinifex sericeus. Many foreign plant species occur around the sandy foreshores at Port Hunter.
