Zostera marina monitoring survey 2011-12-01 publication 2011-08-05 creation 2011-12-01 revision NATENG000343 http://www.naturalengland.org.uk This investigation is a series of reports from 2002 to 2011 on the characteristics and habitat extent of seagrass Zostera marina in the Isles of Scilly. This investigation was contracted by Natural England. The data was gathered by volunteer divers carrying out full monitoring of Zostera marina beds using quadrats and underwater photographs. The dataset includes detailed GIS habitat polygons of seagrass beds and biotope abundance data of other species present within the survey sites.

At each site, a central datum line was lowered to the sea floor from which all bearings and distances were measured. The position of this line was chosen by eye to be approximately central in the bed to be surveyed by means of a surface swim over the bed to determine its extent. Once the central line was positioned, pairs of divers were then sent to take samples from points at randomly selected distances, between 0 and 30m, and bearings, between 0degrees and 359degrees, from the central line. At each of the sites, a 0.25m2 quadrat, constructed of a 0.5m by 0.5m square constructed from copper tubing was positioned so that the bottom left hand corner of the quadrat lay against the right hand edge of the tape at the indicated distance.
