In Your School
WORSENING BLOOMS of Lyngbya have been smothering large areas of mud and seagrass in Roebuck Bay in recent years, posing a threat to the Bay’s remarkable marine biodiversity.
Roebuck students picked up 83kg of rubbish in drains beside their school.
THE CAUSE FOR LYNGBYA BLOOMS is likely to be run-off and polluted groundwater from Broome. Pollutants such as treated wastewater, fertiliser, garden waste and pindan soil enter the Bay directly through stormwater drains during the wet. Contaminants leach through our soils too, flowing into groundwater under Broome (fertiliser, effluent) to eventually, enter the Bay and Indian Ocean. These nutrients can help Lyngbya grow and spread. Whilst research is urgently needed to confirm the cause of Lyngbya blooms, community action is needed now and Broome schools can be a great help.
How your school can help
Adopt a drain
Clean-up the rubbish in a drain in or near your school and remember to record the types and amount of rubbish. Take lots of photos and let RBWG and the media know so they can do a story and promote your fantastic school.
Stencil drain inlets
Contact the RBWG to stencil drain inlets in your school and neighbourhood with the Keep Our Bay Clean logo. You will educate students and the community about preventing nutrients and pindan entering the drains and feeding algal blooms in the Bay.
Grow local native plants
Ask the school to plant local native shrubs and trees – they need less fertiliser and water and attract wildlife. And make sure you label them with Latin and Yawuru names.
Lawns and gardens
Ask your school to adopt Keep Our Bay Clean garden tips such as mulching, slow release fertilisers, soil improvers and sensible use of fertilisers as outlined.
What else can you do?
Quads and trail bikes
Please don’t drive your bikes onto the Bay as this causes the pindan cliffs to erode into the bay. Your bikes also disturb migratory shorebirds, who rest at the water’s edge so they can put on fat stores for their 10,000km flight to Russia & Mongolia.
Volunteer on Roebuck Bay projects
Write a letter
Write to Shire asking them to improve drainage design to reduce nutrient & sediments flowing into the Bay & to clean up rubbish in drains before the wet season each year.
