Lower Nambeelup Brook

The condition of the Lower Nambeelup Brook site (MR31NAMB1), in the middle catchment of Nambeelup Brook was assessed between 16 and 17 November 2017, over a 100-m length of stream.

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

This was the first assessment of this site using the SWIRC methods. At this time no previous assessments of river ecology had been reported, at this site or elsewhere within the wider subcatchment. A list of species is provided at the bottom of the page, click on the images to learn more about each species.

8 fish species and 1 crayfish species were found at this site in 2017, including 3 exotic species of fish, see Table 1, below, for details.

Only fish and freshwater crustaceans (crayfish and shrimp) that typically inhabit river channels are targeted by the standard SWIRC sampling methods.

Note: collection of fauna from WA’s inland aquatic ecosystems requires a license from the Department of Primary Industries and Regional Development (DPIRD) and also the Department of Biodiversity, Conservation and Attractions (DBCA). All species collected must be reported to these agencies as part of license conditions.

One South-western snake-necked turtle (Chelodina colliei) and adult frogs were found at this site.
