Siamanthus siliquosus

Unknown

Overview

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

Siamanthus siliquosus faces severe pressure from rapid deforestation and agricultural expansion across its limited range in Southeast Asian tropical forests. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as remaining populations become isolated in increasingly small forest patches. Mining activities and infrastructure development have further reduced suitable habitat, while the species' slow growth rate and specific ecological niche limit its ability to colonize disturbed areas.

Threat summary

Habitat
