Habitat & Geographic Range

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).

Coastal Rocket Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Venezuela. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Coastal Rocket Frog

Coastal rocket frog (Allobates bromelicola) is a small terrestrial frog in the family Allophrynidae (formerly placed in Dendrobatidae), endemic to coastal lowland forests of Venezuela. Despite its placement near poison dart frogs, Allobates species are non-toxic. This species inhabits the humid leaf litter and bromeliads of coastal Venezuelan forests, where adults care for egg clutches and transport tadpoles to small water bodies including bromeliad phytotelmata. The genus Allobates is widespread across Amazonian and coastal South American forests, characterised by vocal males, ground-level activity, and close parental care. Coastal rocket frog is assessed as Vulnerable by the IUCN, primarily due to restricted range, habitat loss from deforestation for agriculture, livestock grazing, and urban expansion along Venezuela's coast. Climate change poses an additional threat through altered precipitation patterns affecting its bromeliad microhabitats. The species' specific association with bromeliads makes it particularly sensitive to vegetation structure loss. As with many narrowly endemic amphibians, ex-situ conservation programmes and improved habitat protection within its range are considered important management priorities.
