Habitat & Geographic Range

Black Bent

Habitat

Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (South Africa), Asia (Japan), Europe (11 countries), North America (4 countries), Oceania and the Pacific (Australia), and South America (5 countries).

Chocolate Root

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Found across Europe (7 countries) and North America (Canada, United States).

Black Bent

The Black Bent (Agrostis gigantea) is a species in the genus Agrostis. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Chocolate Root

Chocolate Root (Geum rivale), also called Water Avens or Indian Chocolate, is a herbaceous perennial plant in the family Rosaceae, native to cool, moist habitats across Europe, northern Asia, and North America, where it grows in wet meadows, fens, stream banks, and damp woodlands. It produces pinnate leaves with a large terminal leaflet and drooping, nodding flowers whose petals are cream to pink and surrounded by distinctive purplish-red sepals giving the flower a nodding, bell-like appearance when closed. The nodding habit is an adaptation for rain-pollination avoidance, and fertilised flowers develop achene fruits topped with hooked styles for animal dispersal. The name Chocolate Root refers to the aromatic rhizome, which has been used traditionally as a chocolate-like flavouring in beverages and as a medicinal herb with astringent and tonic properties. The IUCN classifies Geum rivale as Extinct in certain regional contexts — notably in some lowland British localities where wetland drainage, river modification, and agricultural intensification have eliminated populations — though the species remains widespread and Least Concern across its global range. Its continued survival depends on the protection of wetland habitats, and it is used as an indicator of ancient, species-rich wetland communities of conservation importance.
