A review of the current methods used to estimate the macroalgal standing stock in England and Wales.
Abstract
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. It places particular emphasis on commercially important species such as large subtidal kelp (mostly Laminaria species) and knotted wrack (Ascophyllum nodosum). This report is significant due to the rise in commercial seaweed activities and the lack of baseline data or standardized methods. It serves as a foundation for discussions with stakeholders and helps address the need for improved approaches in managing seaweed resources.
