Cakile edentula var. lacustris is characteristic; other associates include Chamaesyce polygonifolia, Juncus arcticus ssp. littoralis, Lathyrus japonicus, Xanthium strumarium, and Argentina anserina. This vegetation occurs on sandy beaches of the Great Lakes where wave action causes active sand movement, preventing most plants from becoming established.
