Dendrobium changjiangense
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Dendrobium changjiangense faces severe pressure from overcollection for the ornamental orchid trade, driven by its attractive flowers and rarity value among collectors. Habitat degradation in its limestone karst environments through quarrying and agricultural expansion has fragmented remaining populations. The species' extremely restricted range in Hainan Province makes it particularly vulnerable to localized threats and environmental changes.
Habitat
This epiphytic orchid grows exclusively on limestone cliffs and rocky outcrops in tropical montane forests of Hainan Island, China. It typically occurs at elevations between 400-800 meters in areas with high humidity and filtered sunlight.
