Dendrobium changjiangense

Unknown

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.
