Thirty one transect sites were chosen on rocky shores in Milford Haven. Each transect had up to twenty one stations (mostly around twelve stations). The stations are at 60 cm height intervals down shore from a fixed datum but are not comparable between sites i.e. station five on site ten is not the same height as station five on site twenty. Numbers refer to the traditional seven point abundance scale (1=rare, 7=extremely abundant). Representative stations have been chosen for each site to define as habitat records. They are almost all 100% bedrock.
