Stream ecosystems

In the Auckland region, native forest and wetlands once flanked sparkling streams.

Today, due to land clearance and urban development, only 19 per cent of our 20,000km long stream network passes through native forest.

Our unique native fish need healthy streams and clear passages between open seas and inland streams.

Care for and support streams

• Keep litter and garden waste out of streams.
• Prevent sediments and chemicals from getting into streams.
• Fence streams to keep stock out.
• Plant native plants to stabilise banks, improve habitat and reduce pollution.

To learn how you can care for streams, see our Caring for urban streams guides under Stormwater forms and guides.
