Limnodrilus hoffmeisteri, Tubifex tubifex and Gammarus spp. in low salinity infralittoral muddy sediment
Description (English)
Upper estuary muddy sediments with very low fluctuating salinity, characterised by the oligochaetes Limnodrilus hoffmeisteri and Tubifex tubifex. Other taxa may include Marenzelleria wireni, Gammarus zaddachi, Paranais litoralis and Heterochaeta costata. The biotope contains elements of both freshwater and brackish communities.
Situation: This biotope is found in the transitional zone between the freshwater and brackish environments where tidal currents are sufficiently reduced to allow the deposition of fine silt and the establishment of an infaunal community. It may be found adjacent to A5.223 away from the stronger tidal streams.
Temporal variation: The position of this biotope in the estuary may vary seasonally depending on freshwater input (Gameson, 1982).
