Psychotria schaeferi

Declining

Overview

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

Psychotria schaeferi faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in Puerto Rico's montane forests. Agricultural expansion and urban development continue to reduce the remaining forest patches where this endemic coffee family shrub persists. The species' restricted distribution makes it particularly vulnerable to localized disturbances, with climate change potentially altering the specific microclimatic conditions required for its survival.

Threat summary
