LS.LGS.S.BarSnd recorded () and expected () distribution in Britain and Ireland (see below)
|Distribution of biotope in Britain and Ireland||LGS.BarSnd is a common biotope that occurs on coasts of Britain and Ireland, where the hydrodynamic regime and underlying topography and geology allow accumulation of sandy substrata that is subject to redistribution by tide and currents. The biotope is found particularly at the entrance of the coastal inlets of the south west and is notably absent in the south east of England.|

Freely-draining coarse sandy beaches, particularly on the upper shore, which lack a macrofaunal community due to their continual mobility. Trial excavations are unlikely to reveal any macrofauna in these typically steep beaches on exposed coasts. Burrowing amphipods Bathyporeia spp. or Pontocrates spp. and the isopod Eurydice pulchra may be found in extremely low abundances, but if present in any quantity should be classed as LGS.AEur. Other species that may be found in low abundance may be left behind by the ebbing tide.

The barren shingle/gravel shore biotope (LGS.BarSh) is also represented by this review. In Britain and Ireland the status of the LGS.BarSh biotope is listed as 'uncommon' (Connor et al., 1997b ) and it is differentiated from the LGS.BarSnd biotope solely on the basis of particle size (typically from 4 - 256 mm). LGS.BarSh shores have little associated fine sediment and owing to the mobility of the substratum the biotope does not support macrofauna. Furthermore, trial excavations are unlikely to reveal macroscopic infauna. Any species that are found, such as the occasional amphipod or small polychaete have probably been left stranded by the ebbing tide.
