Gesneria glandulosa

Unknown

Overview

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

Gesneria glandulosa faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in Puerto Rico. The species' restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its native forest understory. Climate change poses additional risks through altered precipitation patterns that could affect the moist conditions this endemic gesneriad requires for survival.

Threat summary

Habitat

Gesneria glandulosa inhabits moist limestone forests and shaded rocky outcrops in the karst regions of Puerto Rico. The species typically grows in humid microhabitats with well-drained soils, often found on limestone cliffs and in forest understory areas with consistent moisture levels.
