Bidens wichmanii

Declining

Overview

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

Bidens wichmanii faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in Hawaii. The species is particularly vulnerable to invasive plant species that outcompete it for resources and alter soil conditions. Climate change poses additional risks through altered precipitation patterns and increased storm intensity, which can damage the fragile ecosystems where this endemic Hawaiian plant survives.

Threat summary

Habitat

Bidens wichmanii inhabits dry to mesic shrublands and open woodlands in the Hawaiian Islands, typically growing on volcanic soils at moderate elevations. The species is adapted to the unique microclimatic conditions of Hawaiian dry forests and shrubland ecosystems.
