Ecosystem Health Monitoring Program
Dr Julia PlayfordDirector
Water Quality and Aquatic Ecosystem Health
Where do we want to be?Healthy Ecosystems Poor Ecosystem Health
Why do we monitor?EHMP based on a conceptual model that integrates scientific understanding with community derived environmental values
Staged Approach in Design and Implementation
Design of Estuarine/Marine Program
Implementation of Estuarine/Marine Program
Establish links between agenciesSet objectives based on stakeholder needs
Extension to Northern & Southern regions
Design of Freshwater Program
Trial of Freshwater Program
Implementation of Freshwater Program
• Assess effectiveness of environmental protection measures (e.g. stormwater controls, STP upgrades, riparian vegetation)
• Meet discharge and other licensing requirements
Monitor Ecosystem Health of Waterways to:
The SEQ Waterways Ecosystem Health Report Card represents a comprehensive marine, estuarine and freshwater ecosystem health monitoring program (snapshot of the health of 18 catchments, 18 estuaries and 9 zones in Moreton Bay)
135 freshwater sites
254 estuarine and marine sites
Report Card Grades reflect ecosystem health of waterways (achieve environmental values)
What is the Report Card?
Most publicised output of the SEQ Healthy Waterways Partnership Easy-to-understand snapshot of ecosystem health A to F Designed to provide an insight into the effectiveness of investments in waterway and catchment managementSplit into two reporting zones, freshwater and estuarine/marineEach has its own objectives, parameters, methods and analysis
SoutheastSetting Guidelines
What goes into a Report Card Grade?Estuarine Report Card
Grade
Water Quality (EHI) (70%)
Biological (BHR) (30%)
i.e. mostly parameters that can be compared to an established guideline
- Bay:
TN, Chl-a, Secchi
depth, Sewage nitrogen (δ15N), Lyngbya- Estuary:
TN, TP, Chl-a, Turbidity, DO
- Bay: Seagrass distribution, Seagrass depth range, Coral cover- Estuary:
Seagrass distribution, Riparian assessment, Sewage nitrogen (δ15N), Nutrient mixing
i.e. Categorised, qualitative, not assessed against a guideline
BHR: Coral monitoring in Moreton Bay
3 x 20m replicate transects at 5 reef sites in Moreton Bay
Boat based
Designed to be used underway
Allows the entire system to be assessed (no sub sampling)
Riparian Assessment Tool
Doing the RAP
Riparian Assessment Tool
• records multiple attributes every second

Freshwater Streams RC 2009
Improvements in biological indicators (macroinvertebrates and fish), reflecting positive influence of higher flows – more native species and lower proportion of alien fish.Decline in nutrient cycling processes in most reporting areas, reflecting the negative influence of catchment loads (with high nutrients) on the nutrient cycling processes in river systems.
Overall score of streams in 2009 (0.805) very similar to previous year’s (0.803).

Never lose sight of the big picture
Trends from long-term datasets (Case: Bremer River)
There have been substantial improvements in some aspects of the estuarine portion of the river system, but those improvements are not yet sufficient to result in changes in EHMP grades.

How is the Report Card Used?
Why has the Report Card been successful?
Because it’s really simple, A is good, F is bad and any grade change has been made for a definable reason (environmental or human induced)
It has consistently generated lots of public interest, particularly following the launch – has become very political
From an early stage it engaged a range of decision makers – politicians, catchment groups etc
We tend to get a good media coverage from the launch
Launch of health-e-waterways : Data Integration System for SEQ waterways – first product is on-line Report Card
New Products: On-line Report Card
Reality check:
Some waterways host infrastructure/ modifications required for society to function and obtaining high levels of ecological condition in some sections may be unrealistic.We need to acknowledge that 150+ years of human impacts won’t be fixed overnight.
