River Habitat Survey (RHS) is Natural Resources Wales standard for collecting data on the physical character and quality of river habitats across the Wales. This dataset provides survey results carried out from 1994 to 2014. The bulk of surveys were carried out between 1994 to 1997 and 2006 to 2008. Surveys are still carried out for specific drivers, for example assessing habitat availability and Water Framework Directive.

Lineage

RHS is a standard field survey of a 500m stretch of river where data is collected in a replicable manner. At 50m intervals a 'spot-check' is conducted to record specific details about bank and channel physical attributes, man-made modifications, land uses and vegetation structure. Surveys conducted prior to 2003 should not be compared with surveys conducted after 2003 as survey methodology changed significantly in 2003.
Additional Information
