Geniostoma clavatum

Declining

Overview

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

Geniostoma clavatum faces severe threats from habitat destruction and degradation across its extremely limited range in the Pacific islands. The species' restricted distribution makes it particularly vulnerable to invasive plant species that alter forest composition and structure. Coastal development and agricultural expansion continue to fragment the remaining suitable habitat, while climate change poses additional risks through altered precipitation patterns and increased storm intensity.

Threat summary

Habitat

Geniostoma clavatum inhabits lowland and montane tropical forests, typically found in moist, shaded understory environments. The species occurs in both primary and secondary forest habitats, showing preference for areas with dense canopy cover and high humidity levels.
