Collated Zostera Seagrass Bed Habitat Boundaries for Wales
Seagrass beds develop in intertidal and shallow subtidal areas on sands and muds. They may be found in marine inlets and bays but also in other areas, such as lagoons and channels, which are sheltered from significant wave action. The three species of Zostera that occur in the UK, Dwarf eelgrass (Zostera noltii), narrow-leaved eelgrass (Zostera angustifolia), and eelgrass (Zostera marina), are all considered to be scarce (present in 16-100 ten km squares) and have some protection through the EC Habitats Directive and is classed as a UK Biodiversity Action Plan (BAP) Priority Habitat. Zostera beds is also on the OSPAR List of threatened and/or declining species and habitats. The OSPAR Convention is the Convention for the Protection of the Marine Environment of the North-East Atlantic. This is a collation of Zostera habitats mapped by the Countryside Council for Wales (CCW) Phase 1 Intertidal Survey, Intertidal Monitoring Contracts, Fisheries Sensitivity maps as well as point sources derived from casework site visits, CCWs data holdings in Marine Recorder and Environment Agency Wales (EAW) Water Framework Directive (WFD) Monitoring Results. The purpose of this data capture was to create a spatial representation for Zostera habitat across Wales. This collation was carried out for reporting on the distribution of OSPAR Habitats in Wales.

The source data was recorded using Intertidal Phase 1 methodology, where the habitats were mapped using GIS against either OS maps or Aerial photographs. Extents mapped recorded during monitoring or casework were either created from GPS tracks or by digitising around waypoints taken in the field. Areas collated for the Fisheries sensitivity maps were created by digitising around known data points using background maps or aerial photographs. Additional beds were digitised from aerial photos. Where areas were mapped by more than one method, the source that provided the largest area was used as this provides an indications of the possible extent of the beds. All Data collected and digitised by specialists.
