Jane Brook - De Grey Retreat

Basin : Swan-Coastal

The condition of the Jane Brook - De Grey Retreat site (site code: JBDG), in the lower catchment of Jane Brook, was assessed between 12 and 13 November 2012, over a 100-m length of stream. The site was also assessed in spring of 2007, 2008, 2009 and 2010.

The assessment was conducted using standard methods from the South West Index of River Condition. Measures chosen for this assessment included fish and crayfish, macroinvertebrates, aquatic habitat, water quality (dissolved oxygen and temperature logged over 24h, and electrical conductivity, pH, colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
