3.2.2     Foredune
          Dogs Beach has an extensively eroded foreshore with a relatively steep dune scarp in places and
          has limited foredune vegetation. Sand accumulation as a result of the groyne at the western end of
          the beach has been colonised by foredune species including a groundcover of Spinifex sericeus,
          Zoysia macrantha and Ipomoea pes-caprae bounded by Acacia sophorae shrubland.

          Sparse Avicennia marina and Excoecaria agallocha mangroves and saltmarsh dominated by
          Sporobolus virginicus and Sesuvium portulacastrum occur at the eastern end of Dogs Beach.

          The southern half of the Spit fronting lower energy estuarine waters supports extensive mangroves
          comprising Avicennia marina, Bruguiera gymnorhiza, Aegiceras corniculatum, Rhizophora stylosa
          and Excoecaria agallocha. Saltmarsh occurs at the upper tidal range dominated by Sporobolus
          virginicus, Juncus kraussii, Clerodendrum inerme, Carpobrotus glaucescens and Sesuvium
          portulacastrum.
