Coryanthes vieirae

Unknown

Overview

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

Coryanthes vieirae faces severe threats from deforestation and habitat fragmentation in its restricted Atlantic Forest range. The species' highly specialized pollination relationship with male euglossine bees makes it particularly vulnerable to ecosystem disruption, as any decline in pollinator populations directly threatens reproduction. Mining activities and agricultural expansion continue to reduce the remaining forest fragments where this orchid persists.

Threat summary

Habitat

This epiphytic orchid inhabits humid Atlantic Forest remnants in southeastern Brazil, growing on tree branches in the forest canopy. It requires the specific microclimate conditions of intact tropical rainforest, including high humidity and filtered sunlight.
