We’re improving the health of our precious wetlands on the Northern Beaches and protecting their threatened vegetation communities with assistance from a NSW Government grant.
The Northern Beaches is unique in having 4 significant freshwater wetland areas that provide vital habitat and breeding sanctuaries for many animals including herons, swamp hens, kingfishers, bitterns, fishing bats, turtles and tree frogs.
Migratory birds use these wetlands as pit-stops on their long journeys, providing them with protection and food.
Our freshwater wetlands can be found at Dee Why, North Narrabeen and Warriewood.
Thanks to assistance from the NSW Environmental Trust’s Saving our Species grant program, Northern Beaches Council’s weed control works have been suppressing highly invasive species which have affected wetland health including:
- Ludwigia, which forms dense colonies in waterways that can change water flow and increase the risk of flooding;
- Salvinia, a breeding habitat for mosquitoes, forming dense mats on the surface of waterways which cause stagnant and smelly water; and
- Coral trees, which are mildly poisonous and significantly reduce soil stability and nutrient levels.
These weeds outcompete native plants, preventing them from growing, which reduces food availability and results in the loss of habitat for native animals.
The grant has helped us protect the threatened vegetation communities found in our wetland areas including freshwater wetlands on coastal floodplains; swamp mahogany forests, and swamp oak forests.
This project has consolidated Council’s protection of these core habitats and will help expand and reconnect wildlife corridors.
Next time you meander through our wetland areas, tread gently and keep your eyes peeled for the distinct vegetation types and diverse plant and animal species.
