Data is collected by competent staff carrying out field shore surveys of macroalgal communities. Data in this dataset is used to calculate the Rocky Shore Macroalgal Index. The rocky shore macroalgal index is composed of five metrics: (i) Species richness (normalised using a shore factor) (ii) Proportion of Chlorophyta (green) species (iii) Proportion of Rhodophyta (red) species (iv) Proportion of opportunists (fast-growing nuisance algae) (v) Ratio of ecological status groups (ESG). Individual metrics are weighted equally and combined within a multi-metric index to assess the structure and composition of intertidal rocky shore macroalgae communities. The species richness component is normalised against a shore factor to enable different shore types to be directly comparable regardless of localised natural environmental factors such as diversity of sub-habitats. Data quality is ensured by participation in annual NMBAQC ring tests. All staff involved in taxonomic identification of specimens must achieve the required standard of the scheme.
