Detached forms of Ascophyllum nodosum are known from several habitats. Ascophyllum nodosum var. mackaii is found on very sheltered shores, in sea lochs and is sometimes common on the west coasts of Ireland and Scotland and in these situations the ecad is sometimes present in great abundance. Sheltered or land-locked bays or situations in the lee of small islands are other favourable positions (Gibb, 1957).
