RAMSAR - Convention on Wetlands of International Importance.


Legislation
National Parks and Wildlife Act, 1974
Threatened Species Conservation Act, 1995
Environmental Planning and Assessment Act, 1979
Fisheries Management Act

Policies
Sydney Regional Environmental Plan No 17: Kurnell Peninsula
State Environmental Planning Policy No 39: Spit Island Bird Habitat
NSW Wetlands Management Policy
Towra Point Aquatic Reserve Plan of Management (NSW Fisheries)
Coastal Resources Atlas for Oil Spills in Botany Bay

Local
- protected as a Nature Reserve
- fences
- signs
- public access restricted
- Towra Team (indigenous group) - removing weeds, planting locally indigenous plants, seed saving
- increased knowledge to improve management
- monitor environmental changes
- recovery plans for endangered species
- pest species management
- protection of freshwater lagoon on Towra by sand-bagging
- reintroduction of locally extinct species
- strategies to reduce chemical and biological agents to remove weeds
- pollution traps
- storm water management
- speed limits on boats
- development controls (housing, etc)
- community-based projects - e.g. Clean Up Australia
- frequent patrols
- education campaigns

Are these strategies effective? 

- There is a wide range of stakeholders who make decisions about the activities which take place in and around Botany Bay. There is limited coordination between different authorities e.g. NPWS, NSW Fisheries, NSW Waterways Authority, NSW Department of Urban Affairs and Planning, Sydney Ports Corporation. Different government departments have different priorities and this can result in conflicts between the agencies. 
- The implementation of managements strategies can sometimes create unforeseen negative consequences. This solves one problem but could create another. 
- Management areas and reserves are not always well planned (e.g. their location and interconnectedness). Areas should be biogeographically representative and allow animals to move between the areas. 
- This marine ecosystem is an "open system" it is affected by the ocean, surrounding urban areas, the Georges River, etc. This makes it difficult to implement management strategies that are effective.
