Twyata Nature Reserve
Basin : Moore-Hill rivers
Catchment : Hill River
The condition of the Twyata Nature Reserve site (site code: HR-05), in the upper catchment of the Hill River, was assessed between 30 September and 1 October 2008, 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 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.
The site was assessed as part of a national assessment of river condition – view report here.
An online condition summary for this site has not been prepared. Please contact the Departments River Science team for site information, and see below for links to information on some of the species found at the site, and some images taken in October 2008.
Fish and crayfish
No fish or crayfish species were found at the site in October 2008.
Note: No fyke nets were set as the site was a series of pools at the time of sampling.
