Funded by the European Maritime and Fisheries Fund (£218,000), the Reserve Effects Tested and Understood to validate Return (RETURN) project will extend the Lyme Bay monitoring programme through to 2019, building on what is already the most comprehensive dataset for temperate reef ecosystems globally. The RETURN project will shed new light on the relative impact of human disturbance compared to natural variability, including extreme storm events.

The data generated over ten years by the team at Plymouth University provides vital evidence to establish the recovery rates and extents for Lyme Bay’s protected marine habitat and associated species, following the exclusion of bottom towed fishing gear from an area of temperate reef.

Management of Lyme Bay

Lyme Bay is home to rocky reefs made up of boulders, cobbles and mixed sediments, providing a complex habitat which is known to support sensitive reef species of national importance, and is regarded as a marine biodiversity hotspot.

The management of Lyme Bay has changed considerably over time, beginning when concerns were raised over the impacts of towed demersal gear on Lyme Bay reef habitats in the early 1990’s. These concerns were initially addressed through the creation of four areas voluntarily closed to bottom-towed fishing gear (totalling 22 km2), which began being implemented in 2001. These areas were not deemed sufficient by Devon Wildlife Trust and other conservationists, who continued to campaign for one large marine protected area (MPA) with statutory levels of protection. In 2008, Lyme Bay became the UK’s largest MPA under a Statutory Instrument (SI) protecting marine biodiversity through the exclusion of bottom-towed fishing gear (scallop dredging and trawling) from a 206 km2 area of seabed (known locally as “The Box”). Static gear fisheries, including potting and netting, were permitted to continue, along with diving for scallops and recreational activities, such as sea angling and SCUBA diving. The Lyme Bay closure is widely regarded as an important test site for UK and European marine conservation policy. Of key importance in this process has been the involvement of fishers who advise on various aspects of management, including the areal extent of the MPA when it was first designated, and the voluntary code of conduct to which fishers adhere within The Box. From 2012, Blue Marine Foundation brought together a working group of stakeholders, including fishers, conservation and marine authorities, and scientists to ensure the successful management of Lyme Bay’s ecosystem and fisheries.
