Introduction 1.1 Background The report has been prepared in conjunction with the proposed development application at the properties of 1-8 Nield Avenue, Greenwich and the lower part of the Nield Avenue road reserve. The report identifies the flora species on the site and fauna species residing on or using the site as part of their foraging range. Specific assessment of the properties has been undertaken to identify habitats of threatened species, populations and ecological communities listed in the schedules of the Threatened Species Conservation Act (NSW) 1995. The report has been commissioned by Murlan Consulting, who have also provided site instructions. Subsequent site inspections and fieldwork were conducted between the 4th March - 5th May, 2008. For the purpose of this report the allotments known as 1, 2, 3, 4a, 4b, 5, 6, 7, 7a & 8 Nield Avenue, Greenwich and the lower part of the Nield Avenue road reserve will be referred to as the subject site. 1.2 Existing site & proposed development Currently the allotments are developed and contain 10 residential dwellings with predominately overgrown landscaped areas. The Nield Avenue road reserve is formed with kerb & gutters, underground services, overhead power lines and mown nature strip areas. The proposed development involves demolition of the existing dwellings and removal of part of the road reserve and construction of a Private Hospital (Marchese, 2008).
