2010 Natural England (NE) Flamborough Head SAC, biotope mapping of the intertidal reef feature dataset https://portal.medin.org.uk/portal/start.php?tpc=010_f76da5b3c156a23b6413fceb790c889f The Institute of Estuarine and Coastal Studies (IECS) were commissioned by Natural England to carry out a biotope survey of 8 monitoring transects around Flamborough Head first surveyed by Howson in 2001. The data gathered from the surveys was used to compare to the original biotopes recorded in 2001, and provide an assessment of the Reef Feature using advice from Regulation 33. Recommendations for future surveying of the transects around Flamborough Head are; to have a consistent survey methodology for greater inter-survey comparability, more regular targeted surveying of transects where significant biotope change has occurred (i.e. Mytilus biotopes of transects 2, 4, and 9) incorporated within a less frequent comprehensive survey programme, and surveying to occur during late summer/early autumn when seaweeds are at greatest diversity. 20211223 20100914
