Redlands Wetland Aggregate
Hilliards Creek and Tarradarrapin Wetland
The Redlands Wetland Aggregate is a series of coastal wetlands located throughout the urban surrounds of Redlands, approximately 25km east of Brisbane. Hilliards Creek is a key catchment in the Redlands area, flowing through Geoff Skinner Wetlands into Moreton Bay. The catchment has several point and non-point source discharges that heavily influence the water quality in the creek. Tarradarrapin Wetlands flows into Moreton Bay at Birkdale. It is surrounded by urban development, facing pressures from stormwater runoff.
The Redlands Aggregate Wetlands are recognised as important wetland habitat areas and form part of the Moreton Bay Ramsar site. It is one of the few remaining wetland aggregates in this area and contains a number of both natural and artificial wetlands. The area is known Koala habitat (Phascolarctus cinereus, vulnerable Qld NCA 1992 in the SEQ Bioregion).
Threats to both systems include high nutrient and sediment loads from adjacent urban areas, causing a decline in water quality in the catchments.
Coastal 20 Rehabilitation Actions:
Commencing mid 2012, onground actions for Hilliards Creek improving the riparian zone, revegetation of buffer zones, and the removal of invasive weed species. These works aim to reduce nutrients and sediment entering the creek, improving the condition and resilience of the catchment. Works at Tarradarrapin Wetlands will focus on reducing stormwater and erosion impacts through strategic revegetation, addressing high nutrient loads from the surrounding urban catchment. An important component of the project is raising the awareness of the local community of the values of the area.
