Vegetation
    The State’s Regulated Vegetation Management mapping maps the vegetation within the northern portion
        of the subject site as Category B Remnant vegetation (see Figure 3). The vegetation is described as an
        area containing “endangered regional ecosystem” and “least concern regional ecosystem”.
    The vegetation is mapped as Regional Ecosystem 12.2.5 which is described as - Open forest to low
        closed forest. Species can include Corymbia intermedia, Lophostemon confertus, Banksia integrifolia
        subsp. integrifolia, B. aemula, Callitris columellaris, Acacia spp., Livistona spp. and Endiandra sieberi.
        Melaleuca quinquenervia in swales. Understorey generally shrubby and can include vine forest species.
        Occurs on Quaternary coastal dunes, beach ridges and sandy banks of coastal streams. (BVG1M: 9f).
    It is noted a small area of RE12.2.7 is also mapped over 404 Lake Cooroibah Road. RE12.2.7 is
        described as - Melaleuca quinquenervia or rarely M. dealbata open forest. Other species include
        Eucalyptus tereticornis, Corymbia intermedia, E. bancroftii, E. latisinensis, E. robusta, Lophostemon
        suaveolens and Livistona decora. A shrub layer may occur with frequent species including Melastoma
        malabathricum subsp. malabathricum or Banksia robur. The ground layer is sparse to dense and
        comprised of species including the ferns Pteridium esculentum and Blechnum indicum the sedges
        Schoenus brevifolius, Baloskion tetraphyllum subsp. meiostachyum, Baumea rubiginosa and Gahnia
        sieberiana and the grass Imperata cylindrica. Occurs on Quaternary coastal dunes and seasonally
        waterlogged sandplains usually fringing drainage system behind beach ridge plains or on old dunes,
        swales and sandy coastal creek levees. (BVG1M: 22a).
    The other regional ecosystem mapped over the northern part of the “bushland” within the site and in the
        adjacent 384 Lake Cooroibah Road is RE12.5.2a - Corymbia intermedia, Eucalyptus tereticornis
        woodland. Other species can include Lophostemon suaveolens, Angophora leiocarpa, Eucalyptus
        acmenoides or E. portuensis, E. siderophloia or E. crebra, Corymbia tessellaris and Melaleuca
        quinquenervia (lower slopes). Eucalyptus exserta is usually present in northern parts of bioregion.
        Occurs on complex of remnant Tertiary surfaces +/- Cainozoic and Mesozoic sediments usually in
        coastal areas with deep red soils. (BVG1M: 9g).
    The site inspection observed the following with respect to the vegetation on site (generally confirms State
        mapping), see Figure 2: -
         Patch 1 (P1): Group of trees around the existing shed and Prototype tents consisted of Eucalyptus
             racemosa, E. robusta, Melaleuca quinquenervia, Angophora leiocarpa, Callitris sp., Alphitonia
             excelsa, Acacia disparrima, E. tereticornis, Lophostemon confertus and L. suaveolens. The
             understorey and groundcover has been removed and the area undergoes maintenance.
         Patch 2 (P2): Vegetation on the western section of 400 Lake Cooroibah Road is open forest with
             trees including Corymbia intermedia, Lophostemon confertus, Eucalyptus racemosa, Melaleuca
             quinquenervia and L. suaveolens. The shrub layer consisted of Glochidion ferdinandi, Lantana
             camara, Acacia disparrima, Hovea acutifolia, Allocasuarina littoralis, Senna pendula var glabrata
             (weed) and Schefflera actinophylla (weed) with a groundcover of sedges, Imperata cylindrica and
             Parsonsia sp.
         Patch 3 (P3): vegetation within the southern property consisted of two communities. The eastern
             part resembles Melaleuca quinquenervia woodland with a sedgy understorey with Eucalyptus
             robusta and Lophostemon suaveolens. The western portion is Eucalyptus/Lophostemon woodland
             to open forest wallum understorey.
         Patch 4 (P4): vegetation to the southern boundary of the Community title area contains a minor
             ephemeral drain which is slashed/mowed when dry. Along the edge is wallum with Angophora
             leiocarpa, Lophostemon polygalifolium, Monotoca scoparia, Melaleuca quinquenervia, Acacia
             maidenii with Baloskion tetraphyllum and Gahnia sieberiana.
