Lot 70 is approximately 2.17 ha in size, a portion of which is covered with native vegetation that may need to be cleared to facilitate development. The City has prepared this Level 2 flora and vegetation survey to support any future federal and / or state environmental impact assessment processes necessitated by proposed vegetation clearing onsite. The fieldwork component of the survey was conducted during September and October 2014. The results of the survey are summarised as follows: 80 species of flora were recorded from the survey area from 30 families of which 19 were recognised as weeds. No Declared Rare Flora Species listed under Section 23 F of the Western Australian Wildlife Conservation Act 1950 or Priority flora species as listed by the Department of Parks and Wildlife (DPaW) were located within the survey area. No flora protected under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) were recorded within the survey area. Key flora species that may provide habitat for the threatened Western Ringtail Possum (WRP) and threatened species of black cockatoo protected under the EPBC Act were identified within the survey area. Key flora for Western Ringtail Possums include Peppermint Agonis flexuosa and key flora for the black cockatoos include Marri, Tuart, Jarrah, Banksia species and introduced Lemon Scented Gums. Synaphea spinulosa was recorded as being potentially at
