Strategic Environmental Assessment (SEA) surveys were comissioned in 2005/06 by the Department of Trade & Industry (now Department for Energy and Climate Change). These surveys, in which JNCC collaborated, acquired multibeam and sidescan sonar data. Ground-truthing data (seabed imagery and biological/sediment samples) was also collected. Although full coverage multibeam and sidescan data was not present for all locations where potential Annex I reef was indicated the available data has provided a good indication of the nature of Annex I reef habitat present within Pobie Bank Reef SAC.Data from the SEA surveys were subsequently analysed to idenitfy areas of Annex I Reef within the Pobie Bank Reef SAC.

2017 annual stock assessment of the The Wash intertidal mussel communities, conducted by the Eastern Inshore Fisheries Conservation Authority. Following a period of stablisation, data showed the mussel stocks have been consistently low since 2009. The 2017 assessment showed a slight decrease in adult recruitment compared to the 2016 assessment, but was still higher than the previous years (2010-2015). Juvenile recruitment continued to improve.

2015 annual stock assessment of the The Wash intertidal mussel communities, conducted by the Eastern Inshore Fisheries Conservation Authority. Following a period of stablisation, data showed the mussel stocks have been consistently low since 2009, however stocks are slowly improving and were slightly higher than the previous year (2014).

Dataset showing the core reef Sabellaria spinulosa areas within the The Wash and North Norfolk Coast SAC and The Wash approaches. The dataset was based on the core reef mapping methodology developed by Natural England and has consistently identified Sabellaria spinulosa reef.

2016 annual stock assessment of the The Wash intertidal mussel communities, conducted by the Eastern Inshore Fisheries Conservation Authority. Following a period of stablisation, data showed the mussel stocks have been consistently low since 2009, however stocks are slowly improving and were slightly higher than the previous years.

Natural England (NE), in partnership with Cefas and the Devon and Severn Inshore Fisheries Conservation Authority (IFCA), conducted a field survey to determine the presence and extent of the biogenic reef feature within the Torbay area of the Lyme Bay and Torbay candidate Special Area of Conservation (cSAC). Surveys were undertaken on the 25th/26th September and 4th October. Ground-truthing sample locations, intended to identify the presence and extent of Mytilus edulis beds on sediment, were identified using indicative signatures from existing acoustic datasets alongside previous point data records and local knowledge. Ground-truthing techniques included the acquisition of video and still images of the seabed. In February 2024 the map was translated to EUNIS 07 classification system by JNCC.

JNCC and Centre for Environment, Fisheries and Aquaculture Science (Cefas) undertook aseabed survey (CEND 22/13 & 23/13) at the North Norfolk Sandbanks and Saturn Reef SCIbetween 4 November and 25 November 2013 on the RV Cefas Endeavour(Vanstaen and Whomersley 2014). The aim was to gather additional seabed data to assist with the development of management advice for the site. Locations of known S. spinulosa reef, along with historic records where reef had been previously observed, were surveyed to assess presence, and where possible, delineate the Annex I biogenic reef feature and characterise associated fauna.
