1. Integrated estuary management Linking catchments to the sea Worshop 22 November 2005, Royal Australasian College of Surgeons, East Melbourne

2. Presentation Outline  Background  Why are we here  What can you expect?  What is going to happen  Where to next  Presentation summary

3. Background  Estuaries are ecosystems of considerable environmental, social and economic value: support a diverse range of species many unique play significant role in regional economies (shipping) great importance to local communities (catch)  Increasing demands resulting from human activities have the potential to result in the degradation of estuaries and threaten their sustainability

4. Estuaries - Linking catchments to the sea NAP/NHT project to minimise pressures on Victorias estuaries 1. Whole of ecosystem scale - upstream/downstream effects 2. Combined (synergistic) affect of human activities 3. Links to potential management intervention - pragmatic approach 4. Turning research outputs into outcomes 1 2 3 4 5

Cudgen Lake Case Study Clothiers Creek Reserves Creek Cudgen Lake Cabarita Casuarina Salt Seaside City Bogangar Management of vegetable crop land: buffer strips, fertiliser application Potential for new rural residential development: sewerage management, riparian buffers Fire buffers, weed restrictions Management of sugar cane for acid runoff: Percentage of catchment adopting these measures Changes to current urban settlements: Increase density, retrofit stormwater management systems Possible new urban development: 1: Cudgen heights (1) 2: Cudgen heights (2) 3: Kings Forest, 4: Duranbah, 5: Hansen 6: Tanglewood) House density, stormwater management, sewerage management, riparian buffers fire buffers, weed restrictions 1 2 3 3 6 4 5

7. What is the purpose of today 1. Information sharing Questionnaire 2. Integrated management Case scenario 3. Communication strategy reference group I don’t know how it started either All I know is its corporate culture

8. What can you expect? 1. Report on the outcomes of the workshop 2. Ongoing communication of research outputs 3. Ongoing communication with respect to estuary management 4.
