Polystachya nyanzensis

Unknown

Overview

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

Polystachya nyanzensis faces significant pressure from deforestation and agricultural expansion across its East African range, particularly affecting the montane and submontane forests where it grows as an epiphyte. Climate change poses an additional threat by altering the moisture regimes and temperature conditions essential for this orchid's survival. Collection for the horticultural trade, while less documented, may contribute to population declines in accessible areas.
