The land surrounding the leases has been identified as proposed Nature Reserve. A survey of the vegetation and flora in December 2003 identified eighteen vegetation units based on their vegetation formations and plant associations. The four most widespread units were: 1. open mallee and thicket/scrub heath characterised by Banksia lemmaniana on upper slopes; 2. mallee and dense shrubs of Melaleuca stramentosa (Priority One) on upper slopes; 3. mallee with an understorey characterised by Melaleuca hamata on mid- and lower slopes; and 4. open
