Hornsby Council has launched a campaign to raise awareness of the fragile seagrass beds in the Hawkesbury Estuary, urging boat users to take care around them.
Mayor Steve Russell said the seagrass beds were vitally important to the health of the estuary, as they act as nurseries for young fish.
“Boat propellers, anchors and mooring chains can very easily damage them – even small scars reduce resistance to erosion and lead to far greater damage,” Cr Russell — who lives on the river and drives his boat to work every day — said.
Hornsby Cuncil has also created a pamphlet and posters, to be distributed throughout the area, with information boaters need to avoid damaging the seagrass.
“The message is a simple one – don’t tangle with seagrass,” Cr Russell said.
■ Avoid shallow water;
■ Observe signs and marker buoys; and
■ Don’t anchor on seagrass.
