Wilyabrup Brook - Downstream Caves Road
Basin : Busselton Coast
Catchment : Wilyabrup Brook
The condition of the Wilyabrup Brook - Downstream Caves Road site (site code: WB2WILY1), in the middle catchment of the Wilyabrup Brook, was assessed between 8 and 9 February 2016, over a 100-m length of stream. At this time no previous assessments of river ecology had been reported.
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, temperature, electrical conductivity, and pH logged every 30 minutes from 15 December 2015 to 30 May 2016 and colour, alkalinity, turbidity and nutrients), fringing vegetation, channel morphology, erosion, connectivity, local land use and flow.
