Miarakandro

Gigasiphon humblotianum

Unknown

Overview

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

Gigasiphon humblotianum faces severe pressure from deforestation and agricultural expansion across its limited range in Madagascar's eastern rainforests. The species' slow growth rate and specific habitat requirements make it particularly vulnerable to forest fragmentation. Slash-and-burn agriculture (tavy) and logging for timber and charcoal production continue to reduce available habitat, while the tree's valuable wood makes it a target for selective harvesting.
