The identification of Champlain beachgrass as a species that is distinct from A. breviligulata is still under investigation, and some authors consider Champlain beachgrass to be a subspecies A. breviligulata ssp. champlainensis (Seymour) P.J. Walker, C.A. Paris & Barrington ex Barkworth. Recent work on morphological differences between varying populations assigned to A. breviligulata and to A. champlainensis do not support the assignment of a distinct species for the latter specimens, despite significant differences. See Delisle-Oldham, M. B.; Oldham, M. J.; Catling, P. M. (2008). "Taxonomic Recognition of Ammophila champlainensis and Morphological Variation in Northeastern North American Ammophila (Poaceae)".
