  1. Lessons in applying CLAMs for Natural Resource Managers Charlie Hewitt GeoLINK charlie@geolink.net.au

  2. CLAM – Coastal Lake Assessment and Management tool • Healthy Rivers Commission 2002 report • Sustainability Assessment tool • Catchment capability • Effect of remedial actions • Combinations of development and remedial actions (i.e. management plan) • iCAM contracted by DNR to prepare CLAMs as SA tools

  3. CLAM – Coastal Lake Assessment and Management tool • Catchment management decision support tool – modelling • Land use • Export rates • Lake processes • Mgt actions • Lake specifics • etc. • Maximise effectiveness of limited funding

  4. CLAM interface • Set combination developments and interventions • … probability distributions

  5. Using CLAMs – 2 main points • Where do CLAMs fit in the NR manager’s toolbox? • How can CLAMs help ensure sustainability of coastal lakes ANDsustainability of coastal lakeplanning processes and documents?

  6. CLAMs among the NR manager’s other tools General management needs Tools Specific management strategy

  7. How do CLAMs fit into the NR manager’s toolbox? • General management needs include: • Policy • Stakeholders • Lake processes • Interventions and land use scenarios • Targets • Justify management Tools Specific management strategy

  8. How do CLAMs fit into the NR manager’s toolbox? General management needs Note: tools inform mgt strategy rather than implement it • Tools include: • WQ monitoring • Hydrological modelling • Participation • Field studies • Landuse • Catchment modelling • Decision support tools(eg. CLAM models) Specific management strategy

  9. How do CLAMs fit into the NR manager’s toolbox? General management needs Tools Specific management strategy • Emphasis influenced by: • Policy • Style • Existing knowledge • Lake specifics • Stakeholder expectations

  10. The Search for the NRM El Dorado • An “everything” tool? • All tools are weak in isolation • eg. hydrological modelling data necessary for dynamic modelling and CLAM modelling • eg. WQ monitoring confirm/inform for all modelling • eg. AP interpretation (landuse data) necessary for dynamic export modelling and CLAMs….etc. • CLAMs ideal for data/tool integration

  11. Understanding and maximising CLAMs • Strengths and weaknesses of CLAMs

  12. Understanding and maximising CLAMs

  13. Understanding and maximising CLAMs

  14. Understanding and maximising CLAMs

  15. Understanding and maximising CLAMs

  16. Understanding and maximising CLAMs

  17. Understanding and maximising CLAMs

  18. Understanding and maximising CLAMs – the data leap of faith • Data vacuum is an occupational hazard • “Anecdotal data” ≠ “no data” • …but CLAMs need data • Do you know your existing land use? • How about riparian planting? • …be prepared to take the leap • So are CLAMs just a series of “hunches”? (combined) • Explicit about assumptions

  19. CLAMs and existing estuary management framework • NSW estuary planning – integrative philosophy • Engage stakeholders • Link with EPS – ID data gaps • Link with EMS – options analysis • CLAM is a means, not an end

  20. CLAMs – it’s all about data/tool integration • Data/tool integration vital – CLAMs ideal • CLAM development – comprehensive consideration • ID data gaps • A data receptacle • Data/tool integration • Help ensure sustainability of ecosystem AND planning process
