ENVIRONMENTAL SUSTAINABILITY — ASSET OVERVIEW<br />

CONDITION OF AQUATIC ECOSYSTEMS<br />

Business As Usual<br />

10 Year Projected<br />

Comments<br />

Our UNESCO World Heritage Listing is dependent upon maintaining the water quality that flows into the surrounding World Heritage National Park.<br />

Similarly, maintaining a high quality of water flowing into Sydney’s water catchments is critical.<br />

The quality of our aquatic ecosystems underpins our biodiversity and the nature tourism and economic values this provides.<br />

Reduction in the quality of our aquatic ecosystems also has the potential for significant loss of community lifestyle, health and well-being.<br />

Risks<br />

Algal blooms and spread of noxious aquatic weeds<br />

Risk of waterborne disease to humans, livestock and pet<br />

Loss of aquatic biodiversity, and the biodiversity which<br />

depends upon it (most diverse aquatic systems in Sydney<br />

basin)<br />

Degraded water quality and related impacts on Sydney<br />

drinking water catchments, and World Heritage values<br />

Erosion and sedimentation<br />

Reduction of tourism income and community lifestyle,<br />

health and well-being, and recreation values<br />

Response<br />

Increased investment in the control of priority aquatic weeds and<br />

in upgrading stormwater treatment systems.<br />

Continue riparian restoration program and community advocacy<br />

and education to support Water Sensitive Urban Design (WSUD)<br />

and contaminant reduction.<br />

Continue Aquatic Ecosystem Monitoring Program.<br />

Continued advocacy and education with external stakeholders<br />

such as Sydney Water, RTA and industry to reduce pollutants in<br />

stormwater runoff.
