The Dry Gully only flows with water after a period of continuous rain followed by a heavy downpour or storm, maybe only once or twice a year and then only for about forty-eight hours. A greater variety of species has been planted in the area closer to Fleming Road where there is more ground moisture including Lomandra spp., Gahnia aspera, Cyperus spp., Dianella caerulea, Pipturus argentus, Crinum pedunculatum, Tremer tormintosa, Mallotus phillipinensis, Hibiscus heterophyllus, Abutilon oxycarpum, Polyscias elegans, Harpulia pendula, Ficus virens, Elaecarpus grandis, Ficus coronata, Corcorus cunninghamii. The amount of natural regeneration occurring throughout the whole of the Dry Gully is remarkable: various native grasses and ground covers plus self seeding occurring as a result of the pristine bushland on either side of the gully.
