This record is for Approval for Access product AfA128. Information regarding the presence, and percentage cover, of seagrass species at specific marine monitoring points held within the Environment Agency’s BIOSYS database (our main database for storing, manipulating and reporting data from freshwater and marine biological surveys at any taxonomic level). These data represent ground-truthing monitoring for the ecological assessment of seagrasses within transitional and coastal waters of England and Wales. Seagrass data on BIOSYS are updated as new monitoring data are made available. Monitoring for seagrass occurs June to September with records being updated after the sampling season. The extracted data is a subset of the full dataset and only includes data collected/owned by the Environment Agency. Attribution statement: © Environment Agency copyright and/or database right 2015.
