Susannah Brook - Reserve No 50069

The condition of the Susannah Brook - Reserve No 50069 (site code: SR241SUSA1), in the middle catchment of the Susannah Brook, was assessed between 15 and 16 November 2018, 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,  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.

Two fish species and one crayfish species were found at this site in 2018, including one exotic crayfish species.
