Rhipidoglossum polydactylum

Declining

Overview

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

Rhipidoglossum polydactylum faces severe pressure from deforestation and agricultural expansion across its East African range, particularly in Kenya and Tanzania where montane forests are being cleared for cultivation. The species' epiphytic lifestyle makes it extremely vulnerable to habitat fragmentation, as it requires mature forest canopy structure that takes decades to regenerate. Climate change poses an additional threat by altering the moisture regimes essential for this orchid's survival in cloud forest environments.

Threat summary

Habitat

This epiphytic orchid inhabits montane and cloud forests between 1,200-2,400 meters elevation in East Africa, growing on tree trunks and branches in humid, shaded conditions. It requires the stable microclimate provided by mature forest canopy, particularly areas with consistent moisture from fog and mist.
