A list of significant species recorded on DEC’s database occurring in the vicinity of the study area. The location of any Declared Rare Flora (DRF) and Priority species identified on site will be recorded using a handheld Global Positioning System (GPS); A description of the vegetation types, vegetation condition and presence of any Threatened Ecological Community’s (TECs) occurring on the site; and Discuss potential impacts the proposal will have on remnant vegetation within the property. 2. EXISTING INFORMATION 2.1 Location Description The study area is located at the Dunsborough and District Country Club on Gifford Road directly adjacent to the golf course on the northern boundary of the Dunsborough townsite. This area is directly adjacent to the Meelup Regional Park. 2.2 Climate The study area experiences a Mediterranean climate with warm summers and cold winters. The temperature at the nearest recording station of Cape Naturaliste for 2011 annual data ranged from an average maximum of 25.8o and an average minimum of 15.6o. The average annual rainfall recorded at Cape Naturaliste is 809.9 mm (Bureau of Meteorology, 2012). 2.3 Landform and Soil The study area is located on the eastern side of the Leeuwin-Naturaliste Ridge. The ridge consists of aeolian limestone underlain by granitic basement rocks. The study area is underlain by banded granitic rocks composed mainly of quartz, feldspar and dark green pyroxene. Soils are shallow and lateritic with a mottled clay subsoil. 8 The study area is located within the Wilyabrup Exposed Rocky Slopes land unit of the Wilyabrup Valleys Land Systems. This land unit is described as low slopes (gradient mainly 5-10%) with shallow rocky soils and some granitic outcrop, exposed to strong winds of the ocean (Tille and Lantzke, 1990). 2.4 Biological Context of the Study Area 2.4.1 Bioregional Data Western Australia supports 53 biogeographical subregions. These bioregions are defined on the basis of geology, landform, vegetation, fauna and climate. The study area is located in the Southern Jarrah Forest subregion of the Jarrah Forest bioregion (McKenzie et al., 2003). The Southern Jarrah Forest subregion is composed of Jarrah-Marri forest in the west grading to Marri and Wandoo woodlands in the east. There are extensive areas of swamp vegetation in the south-east, dominated by Paperbarks and Swamp Yate (McKenzie et al., 2003). 9 3. FLORA AND VEGETATION SURVEY METHODOLOGY 3.1 Survey Methodology The flora and vegetation survey on the project are was undertaken by Ms Kay Lehman an experienced botanist from Eco Logic Environmental Services, on 28 September 2012. A total of 8 hours was spent undertaking the flora and vegetation survey which is considered an adequate time given the area of remnant vegetation within the study area. The vegetation and flora survey involved compiling information from DEC databases, sampling of 10m x 10m quadrat located within representative vegetation types, as well as thoroughly traversing the site on foot to record all plant species present at the time of the survey. This method complies with Eco Logic Environmental Services’ interpretation of the Environmental Protection Authority’s (EPA) guidelines for flora surveys as outlined in Guidance Statement No.51 Terrestrial Flora and Vegetation Surveys for Environmental Impact Assessment in Western Australia (EPA, 2004) and Position Statement No.3, Terrestrial Biological Surveys as an Element of Biodiversity Protection (EPA, 2002). Quadrat dimensions are dependant on the region in which the survey is being undertaken. For the Southern Jarrah Forest subregion it is appropriate to sample quadrats of 10m x 10m dimension. The timing of the survey in spring was considered optimal for the identification of the majority of the Declared Rare Flora (DRF) and Priority listed flora potentially occurring in the area. The major vegetation types were initially delineated using recent colour aerial photography supplemented by on-ground vegetation surveys to ground truth. The perimeter of the golf course area was accessible via vehicle and the survey was conducted by traversing areas of native remnant vegetation within the study area on foot. The proposed mountain bike track of was flagged with tape in the vegetation as well as spray paint along the ground. The proposed track is planned to be approximately 1-2 metres in width. A 10 metre wide study area was assessed along the length of the proposed track. 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. Some species such as Caladenia sp. (orchid) and other delicate plants were also photographed to assist in identification. Plant specimens collected were then identified using local and regional keys and DEC Florabase. A number of specimens were sent to the WA Herbarium for formal identification. Species and site characteristics were recorded from each of the quadrats sampled. A handheld GPS was used to record the location of each quadrat and colour photographs were taken of each quadrat. The following information was collected at each quadrat: Percentage Foliage Cover and Height Cover was estimated visually for each species recorded within the quadrat. Estimates were made to the nearest percentage where possible. Height was visually estimated for all species recorded in the quadrat. Soil Colour, soil texture and soil moisture within each quadrat was recorded. 10 Location MGA coordinates (equivalent to WGS84) were taken from the corner of 10m x 10m quadrats using a hand held Global Positioning System (GPS) to an accuracy of 2m. 3.1.1 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

    Biodiversity Summary for NRM Regions Species List What is the summary for and where does it come from? This list has been produced by the Department of Sustainability, Environment, Water, Population and Communities (SEWPC) for the Natural Resource Management Spatial Information System. The list was produced using the AustralianAustralian Natural Natural Heritage Heritage Assessment Assessment Tool Tool (ANHAT), which analyses data from a range of plant and animal surveys and collections from across Australia to automatically generate a report for each NRM region. Data sources (Appendix 2) include national and state herbaria, museums, state governments, CSIRO, Birds Australia and a range of surveys conducted by or for DEWHA. For each family of plant and animal covered by ANHAT (Appendix 1), this document gives the number of species in the country and how many of them are found in the region. It also identifies species listed as Vulnerable, Critically Endangered, Endangered or Conservation Dependent under the EPBC Act. A biodiversity summary for this region is also available. For more information please see: www.environment.gov.au/heritage/anhat/index.html Limitations • ANHAT currently contains information on the distribution of over 30,000 Australian taxa. This includes all mammals, birds, reptiles, frogs and fish, 137 families of vascular plants (over 15,000 species) and a range of invertebrate groups.

During the time of the survey access was granted to survey eleven properties. The properties surveyed consist of Lot/Number 1,2,3,4 and 38 Bernard Street; Lot 1625 Lion Street, Lot 19, 31 and 49 Johnston Street, and Lot 16 Dean Street and Lot 315 Hummerston Street, Mt Helena. The additional seventeen properties within the study area were assessed for vegetation condition and type from the road in conjunction with aerial photography. This report is the result of a spring botanical survey of the flora and vegetation on the site. The location of the property is shown in Figure 1 and the extent of the property is shown in Figure 2. The recent Flora and Vegetation Assessment within the study area identified a number of flora species within the study area. The vegetation ranged from “Completely Degraded” to “Very Good” Condition, and existing tracks were rated as “Completely Degraded”. Three Vegetation Types at a local level were recorded during the survey. No species of Threatened (T), Priority Flora or Threatened Ecological Community (TEC) pursuant to subsection 2 of section 23F of the Wildlife Conservation Act 1950 and listed by Department of Environment and Conservation (DEC) were located during the time of the survey.
