Bidens campylotheca

Declining

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Bidens campylotheca faces severe habitat degradation from agricultural expansion and urban development across its limited Hawaiian range. The species is particularly vulnerable to invasive plant competition, which alters native ecosystem dynamics and reduces available growing space. Grazing by introduced ungulates further compounds habitat destruction by trampling and consuming native vegetation.

Threat summary

Habitat

This endemic Hawaiian plant species inhabits dry to mesic forests and shrublands, typically growing in volcanic soils at moderate elevations. It occurs in native plant communities that have been significantly reduced and fragmented by human activities.
