Champlain Beachgrass
Ammophila breviligulata ssp. champlainensis (Seymour) P.J. Walker, C.A. Paris & Barrington ex Barkworth

Threats [-]
Beach erosion and the development of a park at the Plattsburgh population threaten regeneration. The plants along the Great Lakes shorelines are threatened by the introduction of the Cape strain (Ammophila breviligulata) that outcompetes the native dune grass.

Conservation Strategies and Management Practices [-]
Along the Great Lakes shores, the non-native Cape strain (Ammophila breviligulata) needs to be eliminated and replaced with the native species. The dunes in Plattsburgh need to be monitored every five years to evaluate how this grass is regenerating.

Research Needs [-]
Research needs to be done on how this species competes with the more vigorous Cape strain (Ammophila breviligulata) and how this applies to management needs. Can this grass be grown, planted, and used as a viable restoration species for Great Lake and Lake Champlain dunes?
