Method steps

1. 3-minute kick sampling method as routinely employed for water quality monitoring by the agency. The sampling method is designed to capture a representative sample of benthic macroinvertebrates from the riffle areas of rivers. It is non quantitative. The samples are routinely analysed to family level for most macroinvertebrate families. Further details of the sampling method, equipment used etc. are available from SEPA Ecology Units

Sites across Scotland on main rivers, selected to provide a representative assessment of water quality in those rivers.
