Psychotria atricaulis

Unknown

Overview

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

Psychotria atricaulis faces significant pressure from deforestation and habitat fragmentation across its limited range in tropical montane forests. Agricultural expansion and logging activities have reduced suitable habitat, while the species' restricted distribution makes it particularly vulnerable to localized disturbances. Climate change poses an additional threat as shifting temperature and precipitation patterns may alter the specific microclimatic conditions this understory shrub requires.

Threat summary

Habitat

Psychotria atricaulis inhabits humid montane forests and cloud forest environments, typically found in the understory of well-preserved tropical forests at elevations between 1,000-2,500 meters. The species requires consistent moisture levels and shade provided by intact forest canopy.
