A River Corridor Survey (RCS) is a survey technique described within National Rivers Authority (1992). It produces standardized maps of vegetation structure along a stretch of a watercourse and provides a detailed outline of the physical habitat available for aquatic animals and a botanical survey.


River Corridor Surveys are a widely accepted way of mapping of vegetation and habitats within a watercourse – it can be used in conjunction with biotope assessments (see below). The comparison of plant structure and composition can inform the selection of restoration measures within scheme.
