(Critically endangered throughout its range.).G2: Imperiled globally because of rarity (6 to 20 occurrences) or because of other factors. demonstrably making it very vulnerable to extinction throughout its range. (Endangered throughout itsrange.).G3: Either very rare <strong>and</strong> local throughout its range or found locally (even abundantly at some of its locations) in a restricted range (21 to 100 occurrences). (Threatened throughout its range.).G4: Widespread <strong>and</strong> apparently secure globally, though it may be quite rare in parts of its range, especially at the periphery.G5: Demonstrably secure globally, though it may be quite rare in parts of its range, especially at the periphery.T#: Global rank of the described subspecies or variety.G#G#: Global rank of species uncertain, best described as a range between the two ranks.G#Q: Indicates some uncertainty about taxonomic status that might affect global rank.STATE RANK (State ranks are based on the status of the taxon within a particular state or province. The state ranks for taxa presented in this guide often differ from the ranks for the same taxa inother states or provinces.).S1: Critically imperiled in state because of extreme rarity (5 or fewer occurrences, or very few remaining individuals), or because of some factor of its biology making it especially vulnerable toextinction. (Critically endangered throughout in state.).S2: Imperiled in state because of rarity (6-20 occurrences), or because of other factors making it very vulnerable to extirpation from the state.S3: Rare or uncommon in the state (21-100 occurrences).SP: Occurring in nearby state or province; not yet reported in state, but probably will be encountered with further inventory.S#S#: State rank of species uncertain, best described as a range between the two ranksStateRankPotamogetonaceae G5 S3S4*Swan Lake Hydroelectric Project January 2013FERC Project No. 2911 Page B‐15 Version: Agency Review
