ReportReport• DiscussionDiscussion
DRMAG Suggested Approach
• Phase 1:– Coordinated reporting of current monitoring
(focus on pressures)
• Phase 2:– New monitoring by NTG
and community– Dependent on extra
resources
Current Work
NRETAS funding $60k:
• Nutrient Monitoring
• Nutrient Limitation Research
• Daly River Monitoring Status Report
Nutrient Monitoring and ResearchWhy nutrients?
• Most likely impact of development: increased nutrients
• Modelling shows potential doubling of algal biomass with nutrient addition
• Some doubt about accuracy of historical nutrient data
Proposed Nutrient MonitoringDry Season 2011
• Extensive nutrient sampling using new more accurate analysis technique
• Determine reference condition and water quality objectives
• Provide opportunities for community involvement in sampling
Nutrient Limitation Research• Limited information on nutrient limitation
and likely effects of nutrient increases
• Nutrient limitation research in collaboration with TRaCK
• Bring together information from different agencies
Status Report
• Provide template for future reporting
• Introduce P-S-R model
• Reporting by subcatchment to highlight areas of greatest pressure
Status Report
• Style similar toDarwin Harbour Report Cards

Status Report (Example only)Stressor Monitoring
• Overview of current stressor monitoring
• Historical WQ monitoring (2005-2010)
Status Report (Example only)Biological Monitoring
• Fish monitoring (DoR)– E.g. catch per unit effort data
• Macroinvertebrates (DoR)– E.g. disused mine monitoring
Status Report - Outcomes
• Highlight sub-catchments of concern• Show current bias towards pressure
monitoring• Highlight gaps in current monitoring• Provide background info for public
consultation• Template for future reporting
Expected publication Mid 2011
