Save the Beeliar Wetlands
It's Not Too Late to Stop ROE 8!
The photos above show the impact of the Roe Highway Stage 8 road reserve on the precious wetlands of North Lake and Bibra Lake. The Environmental Protection Authority (EPA) has already made it clear that this is not acceptable, as stated below.
2003 EPA report Bulletin 1088, highlights the ecological values of North Lake & Bibra Lake
“the EPA concludes that any proposal for the construction of the alignment of Roe Highway Stage 8 through the Beeliar Regional Park would be extremely difficult to be made environmentally acceptable.”
and that:
“the EPA is of the opinion that the overall impacts of construction within the alignment, or any alignment through the Beeliar Regional Park in the vicinity of North Lake and Bibra Lake, would lead to the ecological values of the area as a whole being diminished in the long-term. Every effort should be made to avoid this..."
Acid Sulphate Soils
Acid sulphate soils are naturally occurring and common around wetlands. They do not pose a problem unless disturbed and exposed to air after which they may turn to sulphuric acid – a serious risk to the environment. Sulphuric acid may then leach heavy metals from the soil. Drain realignment during construction of Roe8 is in an area at high risk for acid soils and is likely to expose them. Acid sulphate remediation is difficult and uncertain in terms of outcomes. The Beeliar wetlands are too important to be exposed to unnecessary risks.
Water
Roe8 will be constructed in the water catchment area for Bibra Lake, North Lake, the Beeliar swamps and other wetlands beyond . Cars and petrol cause hydrocarbon and heavy metal contamination of roads. A freeway through a wetland poses a high risk of long term contamination.
