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.

Collared Sparrowhawk

The Collared Sparrowhawk, known scientifically as <em>Accipiter cirrocephalus</em>, is a small bird of prey belonging to the family Accipitridae. As a member of the genus Accipiter, <em>Accipiter cirrocephalus</em> is characterised by its short, rounded wings and long tail, adaptations that enable agile manoeuvring through forest and woodland habitats while pursuing bird prey. The species typically inhabits forests, woodland, and forest edges, where it hunts small birds and occasionally insects. It is reported to occur in Norway according to available range data. Adult males of this species often display a distinctive rufous collar on the nape, which contributes to the species' common name. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Sparrowhawk is currently assessed as Least Concern on the IUCN Red List.
