Vegetation Description
The area applied to clear has been broadly mapped at a scale of 1:250,000 as:
Beard Vegetation Association 1030: Low woodland; Banksia attenuata & B. menziesii (comprising a majority
of the proposed clearing area); and
Beard Vegetation Association 1026: Mosaic: Shrublands; Acacia rostellifera, A. cyclops (in the south) &
Melaleuca cardiophylla (in the north) thicket / Shrublands; Acacia lasiocarpa & Melaleuca acerosa heath.
Rockwater Pty Ltd (2008) undertook a targeted floristic survey for Declared Rare Flora (DRF), Priority Flora
and undescribed taxa in the Cooljarloo West area over 28 days between 30 October 2007 and 7 December
2007. A 10 metre wide corridor was surveyed along the 43.3 kilometres of proposed drill lines and 73.8
kilometres of existing access tracks along historical cleared lines, firebreaks and sand tracks. Approximately
117 hectares was surveyed in total, with most of the nominated existing access routes surveyed from a slow
moving vehicle. New proposed drill lines were typically surveyed on foot. Broad habitat descriptions of areas
likely to be impacted were made, however systematic flora surveying using quadrats was not employed.
Rockwater Pty Ltd (2008) note that vegetation mapping was outside the scope of the flora survey, and
detailed floristic data was not used to characterise each of the vegetation communities described.
Notwithstanding, the flora and vegetation of the local area has been well documented by the numerous
botanical surveys commissioned by Tiwest Pty Ltd, including Mattiske Consulting Pty Ltd (1997), Western
Botanical (2002), Landcare Services (2002; 2004) and Woodman Environmental Consulting Pty Ltd (2006;
2007). Notably, a detailed flora and vegetation survey conducted over the Mullering 3D survey area by
Woodman Environmental Consulting Pty Ltd (2006) overlaps 11 proposed drill lines subject to this clearing
permit application.
