Answer: Don't dump your trash overboard; dispose of properly and recycle. Maintain your boats to reduce oil leaks. Keep your boat or motorized watercraft out of sensitive areas like seagrass beds. Install and maintain marine sanitation devices on your boat.
Explanation:
To maintain these functions, estuaries need our care and protection.
We impact estuaries in many ways. To care for and protect estuaries, we need to consider how our actions affect estuaries and take steps to reduce this impact.
Helping to protect estuaries
Plant trees:
The biggest problem for estuaries is sedimentation. Land clearance has been a major contributing factor to sedimentation. Experts estimate that about 390 million tonnes of sediment washes from the mainland into the sea every year, affecting estuaries. Native vegetation can be planted alongside rivers and streams that enter estuaries and along estuary margins to help stop erosion and trap sediment and nutrient run-off into the estuary.
Fence off stock:
Landowners around estuaries can fence off streams from stock so that they do not cause streambank erosion of sediment or deposit nutrient-laden effluent into the water that will flow into the estuary.
Improve catchment
Improved catchment can help limit pollution that enters estuaries through stormwater run-off.
Restrict fishing activities:
Pay attention to regulations that limit quantity and size of fish and shellfish that can be taken to prevent excessive harvesting.
Respect marine reserves:
Do not take marine life from these areas.
Biosecurity checks on ships:
Ships arriving from overseas are checked to prevent the invasion of exotic species.
Stop reclaiming land:
Stop reclaiming land from estuaries.
Limit pollution:
Help to keep the estuary healthy by not adding solid waste or liquid pollution.
Report threats to estuaries:
Let your local council know if you see something that could be a risk for an estuary – like illegal dumping of rubbish, pollution spills, strange new marine organisms or people cutting down or removing estuarine plants such as mangroves without a permit.
