Psychotria geronensis

Unknown

Overview

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

Psychotria geronensis faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in Puerto Rico. Agricultural expansion and urban development have reduced its montane forest habitat to isolated fragments, while invasive plant species compete for resources and alter the understory composition. Climate change poses additional risks through altered precipitation patterns and increased storm intensity, which can damage the specialized microhabitats this endemic coffee family species requires.

Threat summary

Habitat

This endemic shrub inhabits the understory of montane wet forests in Puerto Rico, typically found in shaded areas with high humidity and well-drained soils. It occurs at elevations between 300-800 meters in remnant forest patches that maintain the specific microclimate conditions required for its survival.
