Restoration of Native Oyster, Ostrea edulis, in South Wales
Native oyster populations throughout Europe suffered a serious decline in the late 19th and early 20th centuries due predominantly to over fishing and associated habitat loss, but exacerbated by anthropogenic and environmental pressures of pollution, disease and a series of cold winters. Historic accounts place Ostrea edulis at the centre of important local fisheries in South Wales back to the Roman occupation of Britain and describe a fishery supporting 200 vessels landing over 9 million oysters at its peak in the 19th century. Ostrea edulis are found on a wide variety of firm and stable seabed habitats where clean hard surfaces exist for larval settlement but it is likely that more complex habitat forms have historically existed including oyster banks and reefs. The aim of this study was to identify the scope and potential approaches for restoration of native oyster populations and habitats in South Wales. The associated report describes the options for practical approaches for restoration of the native oyster in its natural habitat in South Wales to meet UK and Welsh Biodiversity Action Plan (BAP) targets for recovery.

Review of biological and ecological factors, and mapping of the physical environmental factors combined with a review of historical and current documentation and consultation with local fishermen. Historical records date back to the late 1800's. Newer records are as recent as 2010. Reference dates for each bed are included within the data. A wide variety of data sources were utilised but an assessment of confidence was made for each location.
