 Walking areas such as footbridges and steps are rendered "non-slip" with the application of exposed aggregate concrete utilising large river-washed pebbles approximately 20 to in diameter.Understorey plantings in the Fitzalan Creek gully area have no doubt changed over time.Today aroids, gingers and Asian species dominate the head of the gully and a variety of tropical ground cover species enjoy the canopy provided in the lower area of the gully by remnant vegetation including impressive specimens of the paperbark Melaleuca leucadendron, damson plum and Leichhardt trees.
