Australia - Living seawalls bring new life to our city harbor

From snails and seaweed to crabs and limpets, the harbour suburb of Rushcutters Bay is ready to attract more sea plants and creatures with a new living seawall.

The seawall of 90 habitat panels, stretching 24 metres in total, features nooks and crevices to help local marine life thrive.

The project by Sydney Institute of Marine Science (SIMS) was supported with a $20,000 City of Sydney grant.

Project co-lead, associate professor Melanie Bishop, said the project aims to increase biodiversity and improve water quality.

“More than 50% of the Sydney Harbour shoreline is made up of seawalls and research shows these seawalls do not support biodiversity in the same way as natural shorelines,” Melanie said.

“We're bringing back missing microhabitats such as rock pools and crevices. These will provide more space for barnacles and seaweeds to live, while small fish, snails and crabs will be able to hide inside the holes and crevices.”
