monocots |  Printer Friendly Version (PDF) |
Family: Grass Family (Poaceae)
State Protection: Endangered Species 
This level of state protection means: listed species are those with: 1) 5 or fewer extant sites, or 2) fewer than 1,000 individuals, or 3) restricted to fewer than 4 U.S.G.S. 7 ½ minute topographical maps, or 4) species listed as endangered by U.S. Department of Interior. Federal Protection: Not Listed State Rarity Rank: S1
A State Rarity Rank of S1 means: This plant is endangered/critically imperiled in New York because of extreme rarity (typically 5 or fewer populations or very few remaining individuals) or is extremely vulnerable to extirpation from New York due to biological factors. Global Rarity Rank: T2
A Global Rarity Rank of T2 means: This variety/subspecies is imperiled globally because of rarity (typically 6 - 20 known populations or few remaining individuals) or is very vulnerable to extinction throughout its range because of other factors. Did you know? Champlain beachgrass originated from coastal populations that migrated westward along the shores of the Champlain Sea, an arm of the Atlantic Ocean that filled the basins of the St. Lawrence River and Lake Champlain after the retreat of the Laurentide ice sheet about 10,000-11,500 years ago. Our plants were isolated from coastal populations as the land rebounded and cut off the Champlain Sea from the Atlantic Ocean. |

| State Ranking Justification |
| Based on the current circumscription, there is an estimate of six known populations. Most of these are threatened at some level by the introduction of the Cape strain (Ammophila breviligulata). This introduced strain is more aggressive and may genetically swamp the true native population. There are also numerous development and recreational activities that may threaten these populations. |
