Indices
Legend
The charts show the distribution of the site scores for the catchment in a box and whisker
plot. The image to the right shows the meaning of the different elements in the chart.
The number behind the charts is the number of sites with valid data. It can be less
than the total number of sites in the catchment if some data could not be collected.
A description of the indicators and methods used can be downloaded as a PDF file.
Summary
Seven sites were assessed in the Redland reporting area, which was awarded a 2009 Report Card grade of ‘F’, the same as
its 2008 grade of ‘F’. Streams generally failed to meet Ecosystem Health Guidelines, but scores for four of the five
ecological indicators exhibited some improvement in comparison to last year.
The three highest scoring indices for the Redland reporting area during 2008‑09 were GPP (Annual Reporting Area Index
Score = 1.00), R24 (1.00) and Temperature (0.97). The three lowest scoring indices for the area were
δ15N (0.25), PET (0.43) and Proportion Alien (0.49).
The assessment site yielding the highest annual score (indicating the best ecological condition) during 2008‑09 was one
on Tingalpa Creek (site 145‑0025) with a good score of 0.78. The assessment site yielding the lowest annual score
(indicating the worst ecological condition) during 2008‑09 was one on Coolnwynpin Creek (site 145‑0029) with a poor
score of 0.57. While this site is situated within an area of reserve with established vegetation, it is surrounded by
urban development.

Facts
- Total area: 281km²
- Stream network length: 525km
li>
- Local Councils: Brisbane City Council, Logan City Council,
Redland City Council
- Dominant land uses: urban, native bush, intensive
agriculture, market gardens, grazing
- Tingalpa Reservoir impounds Tingalpa Creek
- Four WWTPs discharge into the Redlands/Waterloo Bay catchment
- Rapid urbanisation of the catchment over recent years has led
to the conversion of market gardens/agricultural land to residential
areas and construction of canal estates
