Habitat & Geographic Range

Clustered Bracket

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Widely distributed across Asia (Taiwan), Europe (4 countries), and North America (United States). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Collared Sparrowhawk

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Found in Norway.

Clustered Bracket

Inonotus cuticularis, the clustered bracket, is a polypore fungus in the family Hymenochaetaceae that grows on living and dead hardwood trees across the northern hemisphere. The fruiting bodies are bracket-shaped, overlapping in tiered clusters, with a yellowish-brown to rusty-brown upper surface that darkens with age, and a pale to golden pore surface beneath. This species causes white heart rot in its host trees, degrading the structural integrity of trunks and major branches. It commonly attacks living oaks, beeches, and other broadleaf trees, as well as occurring on dead wood. Inonotus cuticularis is listed as Vulnerable by the IUCN, reflecting its association with old-growth and veteran trees that are increasingly rare in managed European and North American landscapes. The decline of old-growth forest and the removal of veteran trees from managed woodlands and parklands has reduced suitable habitat for many bracket fungi. Conservation of ancient and veteran trees is therefore important for maintaining populations of this and many other wood-decay fungi with similar old-growth associations.

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.
