Clethra javanica
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Clethra javanica faces severe pressure from deforestation and agricultural expansion across its montane forest range in Java and Sumatra. The species' restricted distribution to higher elevation forests makes it particularly vulnerable to habitat fragmentation, as remaining populations become increasingly isolated. Palm oil plantations and subsistence farming have converted much of its original habitat, while climate change threatens to shift suitable temperature and moisture conditions upslope beyond available habitat.
Habitat
Clethra javanica inhabits montane forests at elevations between 1,000-2,500 meters in Java and Sumatra, preferring cool, moist conditions typical of tropical mountain ecosystems. The species grows in both primary and secondary forest environments, often along forest edges and in clearings where it can access adequate sunlight.
