Potamogeton pectinatus community
|Within Vocab||Marine Habitat Classification for Britain and Ireland Version 97.06|
|Definition||Consistently low salinity infralittoral mud with beds of Potamogeton pectinatus. This biotope appears to replace Ruppia beds where the salinity is consistently low as opposed to variable. Other associated species are broadly similar to that of IMS.Rup, with blankets of filamentous green algae such as Enteromorpha intestinalis, Cladophora liniformis and Rhizoclonium tortuosum. The grazing gastropods Hydrobia ulvae and Potamopyrgus jenkinsi are found in this biotope and juvenile Mytilus edulis have been observed settled on Potamogeton leaves and amongst the algae. The nationally scarce charaphyte Lamprothamnium papulosum may be found to some extent in this biotope but more often in neighbouring habitats (see Plaza & Sanderson 1997). Mysids and sticklebacks Gasterosteus aculeatus can be found swimming amongst the vegetation. Mya arenaria may be found in some examples of this biotope, but the infaunal component of this biotope requires further investigation. This biotope is further described as NVC type A12 (Rodwell 1995).|
