Bidens australis
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Bidens australis faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range. Invasive plant species compete directly with this endemic species for resources, while altered fire regimes and grazing pressure from livestock further degrade its specialized habitat requirements. Climate change poses an additional threat through shifting precipitation patterns that affect the wetland margins where this species typically establishes.
Habitat
Bidens australis typically inhabits wetland margins, seasonal pools, and moist grasslands in temperate regions. The species shows preference for areas with fluctuating water levels and disturbed soils that provide optimal germination conditions.
