Kelp forests are widely distributed along temperate coastlines, where they provide food and habitat for a wide range of organisms and fuel inshore foodwebs. Due to the often inaccessible nature of kelp forests, fundamental knowledge gaps pertaining to their structure and functioning is lacking in many regions, hindering management and conservation efforts. To address this knowledge gap, we established and maintained several long-term kelp forest monitoring sites along the wave-exposed open coastline of the UK. Using scientific diving and other sampling methods, we: (i) examined local biodiversity, habitat structure and associated community composition, (ii) estimated rates of primary production and detritus release, and (iii) conducted manipulative experiments to assess the resilience of these habitats to physical disturbance. A summary of the findings to date, their application for sustainable management, and priority areas for further research are presented.
