Coryanthes toulemondiana

Declining

Overview

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

Coryanthes toulemondiana faces severe threats from deforestation and habitat fragmentation across its limited range in Central American cloud forests. The species' highly specialized pollination relationship with male euglossine bees makes it extremely vulnerable to ecosystem disruption, as any decline in pollinator populations directly threatens reproduction. Agricultural expansion and logging activities continue to reduce the pristine montane forest habitats essential for both the orchid and its pollinators.

Threat summary

Habitat

This epiphytic orchid inhabits humid montane cloud forests at elevations between 800-1500 meters, growing on tree branches in areas with consistent moisture and filtered sunlight. The species requires the specific microclimate conditions found in undisturbed primary forest canopies.
