Upper Chapman Brook - Berry Farm

The condition of the Upper Chapman Brook - Berry Farm site (site code: BR50UPPE1),  in the middle catchment of the of the Upper Chapman Brook, was assessed between 13 and 14 February 2019, 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.

Four fish and two crayfish species were found at this site in 2019. No exotic species were found.

Notably, Galaxiella munda (western mud minnow) was found in relatively high abundance (~20). This is of ecological significance as it is a rare species known to often occur in low abundance within their natural range (thus chance of detection is naturally low). This species is listed as Lower Risk/Near Threatened on the 1996 IUCN Redlist of threatened species.

Note: only fish and crayfish are targeted by sampling methods, however where other species were caught and/or observed they are included below.
