Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Plicate Sweet-grass faces severe threats from habitat loss due to wetland drainage, agricultural conversion, and urban development across its range. Water pollution from agricultural runoff and altered hydrology from dam construction and water diversions further degrade the shallow water and marshy habitats this species requires for survival.
Key Facts
Habitat & Distribution
Shallow freshwater wetlands, marshy pond margins, slow-moving streams, and seasonally flooded grasslands, typically in areas with fluctuating water levels. Also found along ditches, canals, and other disturbed wetland habitats with nutrient-rich soils.
