Metrosideros humboldtianus

Unknown

Overview

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

Metrosideros humboldtianus faces severe pressure from invasive plant species that outcompete native vegetation and alter forest composition in its limited montane habitat. Habitat degradation from feral ungulates, particularly pigs and goats, damages the understory and soil structure essential for regeneration. Climate change poses an additional threat by shifting temperature and precipitation patterns in the species' restricted high-elevation range, potentially forcing populations beyond their adaptive limits.

Threat summary

Habitat

This endemic tree species inhabits montane cloud forests and wet forests at elevations between 600-1,200 meters in the Marquesas Islands. It typically grows in areas with high humidity and frequent cloud cover, often on steep volcanic slopes with well-drained soils.
