What are Aquatic Ecosystem Condition Reports?
Aquatic Ecosystem Condition Reports provide a comprehensive picture of the ecological condition of sites sampled in creeks and lakes, and rate each site on a scale from Excellent through to Very Poor using an ecological condition gradient. Further information on what data is collected and how the sites are rated is provided in the document Environment Protection Authority: Aquatic Ecosystem Condition Reports.
How often are Aquatic Ecosystem Condition Reports released?
Aquatic Ecosystem Condition Reports will be released annually presenting assessments of sites sampled the previous year.
What data or information is used to create an Aquatic Ecosystem Condition Report?
A range of biological, chemical and physical information is recorded at each sampling site including nutrients, salinity, dissolved oxygen, water temperature, algal growth, macroinvertebrate data, aquatic vegetation coverage, riparian vegetation coverage and sediment type and condition. Further information on the data collected and how it is used is provided in the document Environment Protection Authority: Aquatic Ecosystem Condition Reports.
Do other states produce Aquatic Ecosystem Condition Reports?
Aquatic Ecosystem Condition Reports or report cards of a similar nature have been produced in other states as a means of assessing the ecological and water quality condition of waters in their regions. Queensland and Victoria have report cards assessing the ecological and water quality condition, and New South Wales has report cards based on water quality data only.
What do the different ratings mean?
The ratings provide information on the ecological condition of each site. Sites are rated on a scale between Excellent and Very Poor using an ecological condition gradient. These ratings are explained in more detail in the document Environment Protection Authority: Aquatic Ecosystem Condition Reports.
Can I download any raw data?
Water quality measurements, habitat data and a list of macroinvertebrates found at each site is available for downloading. Data can be downloaded in two ways: through the Aquatic Ecosystem Condition Report listed under 'Further information' near the bottom of each report or through the map function in WaterConnect.
Are there any simple information brochures I can download?
Information brochures outlining the process used and the data collected for the Aquatic Ecosystem Condition Reports can be found at Environment Protection Authority: Aquatic Ecosystem Condition Reports.
Are there any technical reports that explain the scientific methods?
Expert panel assessments are available to download here:
- 2008 (Kangaroo Island, Adelaide and Mount Lofty Ranges, Northern and Yorke, and SA Murray–Darling Basin NRM Regions)
- 2009 (SE NRM Region)
- 2010 (Eyre Peninsula NRM region)
- 2010 (SA Murray–Darling Basin NRM region).
These reports explain how the scientific information was used to derive the rating for each site. More general information on the process used is provided in the document Environment Protection Authority: Aquatic Ecosystem Condition Reports.
Where can I find definitions for some of the words used?
A glossary has been provided with explanations and definitions of the some of the more technical terminology used in the Aquatic Ecosystem Condition Reports.
