Arctic Burreed

The Arctic Burreed (Sparganium natans) is a species in the genus Sparganium. It is currently classified as Near Threatened on the IUCN Red List. Typically found in grasslands, wetlands, forests, and cultivated landscapes.

clustered burreed

Sparganium glomeratum, the clustered burreed, is an aquatic or semi-aquatic perennial herb in the family Typhaceae native to circumboreal wetland habitats across northern Europe, northern Asia, and North America. The genus Sparganium is characterized by distinctive spherical, spiky fruiting heads that give burreeds their common name. S. glomeratum is distinguished by its clustered arrangement of male and female flower heads, which are positioned closer together than in other burreed species. The plant grows in shallow water or waterlogged soils in lakes, ponds, slow streams, fens, and marshes, often forming emergent stands alongside other wetland vegetation such as sedges, rushes, and other aquatic plants. Like other aquatic macrophytes, it provides important habitat structure for aquatic invertebrates, fish, and waterfowl. The starchy rhizomes and starch-rich fruits are consumed by waterfowl and other wildlife. S. glomeratum has not been formally evaluated by the IUCN for global conservation status, but is considered secure across most of its circumpolar range in intact boreal and temperate wetlands.
