NECR528 Edition 1 A Review of the Current Methods Used to Estimate the Macroalgal Standing Stock in England and Wales (NECR528)

This report provides Natural England and Natural Resources Wales with a useful review and assessment of the tools and methods used to calculate macroalgal distribution and biomass around UK coasts, with particular emphasis on commercially important species such as large subtidal kelp (mostly Laminaria species) and knotted wrack (Ascophyllum nodosum). This is important because of the increase in commercial seaweed activities and interest along with the lack of standing stock baseline or standardisation of approach. The report can be used as a basis for discussions with interested parties.
