Lyme Bay is home to temperate reefs that provide structurally complex habitats for a biodiverse range of species, such as the protected pink sea fan (Eunicella verrucosa), ross coral (Pentapora foliacea) and King Scallop (Pecten maximus), making the reefs nationally important for both conservation and fisheries.. Concerns were first raised in the early 1990s, about the impacts of bottom-towed fishing in the area, such as scallop dredging and trawling.
Four areas totaling 22 km2 were closed to bottom trawling under voluntary agreements in 2001, which had varying degrees of success. In 2008, the Lyme Bay Marine Protected Area (MPA) was designated under a Statutory Instrument (SI), protecting 206 km2 of seabed from bottom-towed fishing. Since then, the University of Plymouth aMER group have monitored the recovery of species and habitats in the area, spanning several project iterations and creating the most comprehensive ecological dataset for MPA monitoring in the UK.
In the 14 years since its implementation, aMER have assessed the areas recovery using a variety of video equipment, including annual towed flying array (TUV), baited camera (BRUV) and soil grab samples to monitor benthic, pelagic and infauna species. Through these interdisciplinary annual surveys, the team have compiled the most in-depth datasets for temperate reef ecosystems in the UK.
The positive results of the monitoring programme have played an integral role in the continued implementation of the protection zone, widely considered as both a national marine biodiversity hotspot and an important blueprint for future UK and international marine protected area policy.
The annual Lyme Bay Long Term Monitoring Project was first funded by DEFRA and Natural England and has received significant European Martitime Fisheries Funding through projects such as RETURN and Recover-Reef. The impacts of extreme storm events in 2014 were monitored using funding from NERC, The Pig Shed Trust and the local fisheries through the South West Fish Producers Organisation. Natural England has continued to support the monitoring throughout and is now part of a collaborative long-term funding collaboration with DEFRA, BLUE and the University of Plymouth. The continued monitoring, provides essential evidence on MPA management effectiveness and the sustainability of the fishing practices that operate inside the MPA.
