Metrosideros patens

Declining

Overview

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

Metrosideros patens faces severe pressure from invasive plant species that outcompete native vegetation and alter forest composition in its limited Hawaiian range. Habitat degradation from feral ungulates, particularly pigs and goats, damages the understory and creates conditions favorable to invasive species establishment. Urban development and agricultural expansion continue to fragment the remaining native forest patches where this endemic tree occurs.

Threat summary

Habitat

This endemic Hawaiian tree inhabits mesic to wet forests on volcanic slopes, typically occurring in mixed native forest communities at elevations between 300-1,200 meters. It grows in areas with well-drained volcanic soils and moderate to high rainfall, often associated with other native Hawaiian forest species.

Why is Metrosideros patens classified as Endangered?
Metrosideros patens is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Metrosideros patens faces severe pressure from invasive plant species that outcompete native vegetation and alter forest composition in its limited Hawaiian range. Habitat degradation from feral ungulates, particularly pigs and goats, damages the understory and creates conditions favorable to invasive species establishment. Urban development and agricultural expansion continue to fragment the remaining native forest patches where this endemic tree occurs.
Where does Metrosideros patens live?
Metrosideros patens occurs in France, and New Caledonia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Metrosideros patens?
The main threats to Metrosideros patens are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
