Bidens bipontina
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Bidens bipontina faces severe threats from urban development and agricultural expansion across its extremely limited range in Hawaii. The species is particularly vulnerable to habitat conversion as coastal and lowland areas are developed for housing and commercial use. Invasive plant species compete directly with this native Hawaiian endemic, while altered hydrology from development disrupts the wetland conditions it requires for survival.
Habitat
This Hawaiian endemic inhabits coastal wetlands, mudflats, and disturbed areas near sea level. It typically grows in seasonally flooded areas and along the margins of fishponds, requiring specific moisture conditions that are increasingly rare due to development pressure.
