5.0 SUMMARY
    The vegetation within the Carramar site is mapped as non-remnant under the Vegetation
     Management Act 1999.
    The vegetation is not designated Essential habitat for Endangered, Vulnerable or Near
     threatened fauna species.
    The subject site lies within a Protected Plants high risk area.
    The vegetation on site was found to consist partly of a Melaleuca wetland, with native
     sedge / grass and fern understorey, and partly of a landscaped area with scattered native
     shade trees and introduced species.
    Although very limited in extent, the vegetation in the Melaleuca wetland area exhibits the
     characteristic structure and composition of Regional Ecosystem 12.3.5 – Palustrine
     wetland, with tall Eucalypt emergents (Eucalyptus robusta and Corymbia intermedia) of
     significant height (20 metres) and girth (500 millimetres dbh) growing over a sub-canopy of
     Paperbark tea tree (Melaleuca quinquenervia), Black she oak (Allocasuarina littoralis) and
     dense thickets of Tall saw sedge (Gahnia clarkei), Bungwall (Blechnum indicum) and Harsh
     ground fern (Hypolepsis muelleri).
    Species composition is approximately 50% native, 50% introduced on the western edge,
     and 90% native, 10% introduced on the eastern edge with a moderate diversity of species
     recorded.
    No EVNT flora species were detected within the survey area or 100 metre buffer.
    Two EPBC-listed fauna species, Grey headed flying fox (Pteropus poliocephalus -
     Vulnerable) and Swamp crayfish (Tenuibranchiurus glypticus - Endangered) were identified
     in the survey area, in addition to a number of Least concern mammals, reptiles, birds and
     amphibians.
    Breeding habitat for Endangered Swamp crayfish (Tenuibranchiurus glypticus) occurs in the
     ephemeral ponds and stormwater outlets in the Melaleuca wetland east of the carpark.
    The Melaleuca wetland with sedge understorey may provide suitable breeding habitat for
     EVNT listed Wallum frogs (Crinia tinnula and Litoria freycineti), and the ponded water
     around the culverts may provide suitable breeding habitat for Tusked frog (Adelotus brevis),
     however no listed amphibians were found during the survey.
    The survey area does not lie within a Koala Assessable Development Area and as such is
     not subject to the provisions of the South East Queensland SPRP for conservation of Koala
     bushland habitat. Vulnerable listed Koalas (Phascolarctos cinereus) are known to occur
     within one kilometre and may traverse the site on occasion.
    There are two pest fauna species present, Asian house gecko (Hemidactylus frenatus) and
     Cane toad (Rhinella marina).
    Six Restricted Invasive Plant species are present throughout the corridor, including
     Singapore daisy (Sphagneticola trilobata) and Groundsel (Baccharis halmifolia). The
     General Biosecurity Obligation designated under the Biosecurity Act 2014 requires
     everyone to take all reasonable and practical steps to minimise the risks associated with
     invasive species.
