Myristica teysmannii

Unknown

Overview

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

Myristica teysmannii faces severe pressure from deforestation and habitat conversion throughout its limited range in Southeast Asian lowland forests. Palm oil plantations and agricultural expansion have fragmented remaining populations, while selective logging targets the mature forest canopy this nutmeg species requires for reproduction. The species' slow growth rate and specific pollination requirements make recovery particularly challenging once local populations are eliminated.

Threat summary

Habitat

Myristica teysmannii inhabits primary and secondary lowland rainforests, typically found in the understory and middle canopy layers at elevations below 800 meters. The species requires mature forest conditions with consistent humidity and is particularly associated with well-drained soils in areas with high annual rainfall.
