Cliff Net-bush

Cliff Net-bush, Calothamnus rupestris, is a small shrub in the family Myrtaceae endemic to southwestern Western Australia, one of the world's recognized biodiversity hotspots. Calothamnus species, known as net-bushes or one-sided bottlebrushes, are characterized by their distinctive flower clusters arranged in a one-sided bottlebrush pattern along woody stems, with brush-like red staminal bundles typical of the genus. Cliff Net-bush grows on cliff faces, rocky slopes, and granite outcrops in the kwongan heathland of the Southwest Australian Floristic Region, tolerating the thin, nutrient-poor soils and periodic drought characteristic of these rocky substrates. The flowers provide nectar for native honeyeaters and insects. Like the majority of southwest Australian endemic plants, Cliff Net-bush is adapted to the ancient, nutrient-impoverished soils of the Gondwanan continent and the Mediterranean-type climate with hot, dry summers and mild, wet winters. Threats facing southwest Australian heathland endemics include habitat clearing for agriculture, dieback disease caused by the introduced pathogen Phytophthora cinnamomi, altered fire regimes, and climate change. The conservation status of Calothamnus rupestris requires monitoring given the overall pressure on southwest Australian flora.

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.
