Overview

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

Hymenorchis serrulata faces severe threats from deforestation and habitat conversion in its limited montane forest range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while its specialized epiphytic lifestyle requires specific microclimate conditions that are easily disrupted by forest fragmentation. Climate change poses an additional threat by altering the temperature and humidity regimes essential for this orchid's survival.

Threat summary

Habitat

This epiphytic orchid inhabits humid montane forests at elevations between 1,200-2,000 meters, growing on moss-covered tree trunks and branches in cloud forest environments. It requires consistent moisture and filtered light conditions typical of undisturbed tropical mountain forests.
