Organised and run by the Marine Biological Association (MBA) in Plymouth, annual BioBlitz surveys take place in/around Plymouth (sites in Devon and Cornwall). The aim of this survey was to record as many species as possible as being present within a set survey area in Wembury, Devon (UK) over 24-hours. A variety of different methods were employed, including times-species searches, plankton netting, Seine-netting, Pond-dipping with nets, mammal trapping, walkovers, push-netting, grab/core, transect/quadrat, and including Dive and snorkel surveys, although most records were ad-hoc sightings made during the 24 hour survey. This was the 11th annual survey run by the MBA. All records were verified by experts and data team staff.
