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
Eight sites were assessed in the Stanley reporting area, which was awarded a 2009 Report Card grade of ‘B’, slightly
lower than its 2008 grade of ‘B+’. Streams were generally in good condition; but the grade declined due to a lower score
this year for the Nutrient Cycling indicator.
The three highest scoring indices for the Stanley reporting area during 2008‑09 were pH (Annual Reporting Area Index
Score = 1.00), DO (1.00) and Proportion Alien (0.97). The three lowest scoring indices for the area were δ13C
(0.63), δ15N (0.72) and Conductivity (0.88).
The assessment site yielding the highest annual score (indicating the best ecological condition) during 2008‑09 was one
on Sheepstation Creek (site 143‑0028) with an excellent score of 0.96. The assessment site yielding the lowest annual
score (indicating the worst ecological condition) during 2008‑09 was one on Delaney Creek (site 143‑0066), albeit with a
good score of 0.78. This site is located within an area of agricultural land.
