INTRODUCTION COOE Pty Ltd was commissioned by Wallbridge Gilbert Aztec (WGA) to conduct a native vegetation clearance assessment, on behalf of the City of Playford, and to assess the proposed clearance envelopes against the Clearance Requirements of the Native Vegetation Act 1991 and Native Vegetation Regulations 2017. WGA has been engaged by the City of Playford to undertake the detailed design and documentation of upgrades to Bassnet Road (between Sambell Road and Humbug Scrub Road) (Appendix A) in the suburb of Humbug Scrub. The proposed native vegetation clearance is required as part of the City of Playford’s program to upgrade roads within its local government area. The applicant is applying to clear native vegetation within both roadside reserves either side of Bassnet Road, Humbug Scrub (between Sambell Road and Humbug Scrub Road) (Figure 1). As the City of Playford are applying to clear native vegetation for the upgrading of Bassnet Road the proposed development and associated native vegetation clearance is considered to comply with Regulation 12(34): Infrastructure of the Native Vegetation Regulations 2017. 2. LAND USE DESCRIPTION AND HISTORY 2.1 Bassnet Road, Humbug Scrub The 2.7km section of Bassnet Road proposed for upgrading is situated between Sambell Road and Humbug Scrub Road in the suburb of Humbug Scrub and is located approximately 6-9km south-west of the township of Williamstown (Figure 3). This section of road corridor is adjacent to several cadastral boundaries in the Hundred of Para Wirra. The landform in the region is described as hilly uplands on metamorphics. The region contains pine plantations, open parklands with sown pasture understorey and remnant native vegetation. The native vegetation associations adjoining this section of Bassnet Road are mapped as the following communities: • Eucalyptus fasciculosa, Eucalyptus leucoxylon ssp. leucoxylon and Eucalyptus odorata woodland; • Eucalyptus goniocalyx ssp. goniocalyx and Eucalyptus fasciculosa woodland; • Eucalyptus goniocalyx ssp. goniocalyx woodland; and • Eucalyptus camaldulensis var. camaldulensis and Eucalyptus leucoxylon ssp. leucoxylon woodland (Source: NatureMaps, Government of South Austrlia, 2018. https://data.environment.sa.gov.au/NatureMaps/Pages/default.aspx)
