Octamyrtus halmaherensis

Unknown

Overview

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

Octamyrtus halmaherensis faces severe threats from deforestation and habitat conversion on Halmahera Island, where its extremely limited range makes it vulnerable to any forest loss. Mining activities and agricultural expansion have fragmented the remaining lowland forest patches where this endemic myrtle occurs. The species' restricted distribution to a single island ecosystem amplifies the impact of these localized threats, with climate change potentially altering the specific microclimatic conditions it requires.

Threat summary

Habitat

This endemic myrtle species inhabits lowland tropical rainforests on Halmahera Island in the North Maluku province of Indonesia. It occurs in primary forest understory environments at relatively low elevations, requiring the humid, stable conditions typical of intact Indonesian rainforest ecosystems.
