The bushland understorey is dominated by impenetrable Lantana. Some native understorey species were also observed in the understorey stratum.

It is assumed that the proposed pathway will be built along the cleared grass area beside the creekbank and adjacent to the degraded remnant bushland. Many dead and dying trees were observed in the area. Many native birds were observed utilising the Lantana thickets in the forest understorey. Significant geological features occur along this section of creekline. It is recommended that intensive weed clearance be undertaken and the cleared area planted between Baden Powell Place and Euclid Street.
