| Preferred label | [Hediste diversicolor] and [Corophium volutator] in littoral mud |
| Definition | Sheltered estuarine shores of sandy mud, which may become firm and compacted if present in the upper shore where there is more time for drainage between high tides. An anoxic layer is usually present within the first 5 cm of the sediment. The infauna is very sparse, usually only the ragworm [Hediste diversicolor] and the amphipod [Corophium volutator] are present in any abundance. Occasionally, oligochaetes or the spire shell [Hydrobia ulvae] may be present. [Corophium multisetosum] may also be found. There may be organic pollution of the sediment. Situation: Hed.Cvol may occur on the same shores as HedMacScr, HedMac, NhomAph, and Hed.Str. Higher up on the shore, and/or further towards the head of the estuary, Hed.Ol may occur, changing to Tben at the upper extreme of the estuary. Temporal variation: [Enteromorpha] spp. or [Ulva lactuca] may form mats on the surface of the sediment during the summer months, particularly in areas of freshwater influence and/or where there is nutrient enrichment. |
