Psychotria marchionica
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Psychotria marchionica faces severe pressure from habitat degradation across its limited range in the Marquesas Islands. Invasive plant species, particularly aggressive weeds and non-native shrubs, are displacing native vegetation and altering the understory composition where this endemic coffee family species thrives. Human activities including agricultural expansion and infrastructure development continue to fragment the remaining suitable habitat patches.
Habitat
This endemic species inhabits the native forests and woodland areas of the Marquesas Islands in French Polynesia. It typically grows in the understory of mesic forests at moderate elevations, preferring areas with consistent moisture and partial shade beneath the forest canopy.
