The plants drift in large, spherical masses in sheltered waters. An increase in water flow rate may cause plants to be torn off the substratum or the plant with the substratum will be mobilised and may be moved to conditions unsuitable for the growth of the species. Growth is apical. Occurrence dataset https://www.nmni.com/CEDaR/CEDaR-Centre-for-Environmental-Data-and-Recording.aspx accessed via NBNAtlas.org on 2018-09-25.

Ascophyllum Nodosum, is a large, common brown sea vegetable from the northern Atlantic Ocean, also known as Norwegian Kelp, KNotted Kelp or Knotted Wrack. & Vadas, R.L., 1991. Fish, J.D.

Available from: Ocean Biogeographic Information System. Even several years after small scale cutting shore cover was reduced and there were significant decreases in the cover of other species like. Occurrence and distribution of free-living Ascophyllum nodosum in Newfoundland. Chock, J.S. The MarESA approach reflects the recent conservation imperatives and terminology and is used for sensitivity assessments from 2014 onwards. The species has long strap like fronds with large egg-shaped air bladders at regular intervals. Description: Dense Green Powder with pungent Seaweed smell. Seaweeds have no known mechanism for visual perception. mackayi If smothering occurred while the plant was immersed, fewer surfaces would be covered allowing some surfaces to be unaffected. Sheltered or land-locked bays or situations in the lee of small islands are other favourable positions (Gibb, 1957). A check-list and atlas of the seaweeds of Britain and Ireland.

The MarLIN approach was used for assessments from 1999-2010. Description: Ascophyllum nodosum is olive green in colour, turning dark green/brown when dried. The frond has extensive dichotomous branching and bears few air bladders.
