Oparanthus hivoanus

Declining

Overview

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

Oparanthus hivoanus faces severe threats from habitat destruction due to agricultural expansion and urban development on its native Pacific islands. The species' extremely limited range makes it particularly vulnerable to invasive plant species that outcompete native vegetation. Climate change poses additional risks through altered precipitation patterns and increased storm intensity affecting its specialized habitat requirements.

Threat summary

Habitat

Oparanthus hivoanus inhabits specialized coastal and lowland forest environments on Pacific islands, typically growing in well-drained soils with specific moisture and light conditions. The species requires intact native vegetation communities and is sensitive to habitat fragmentation and disturbance.
