Amorphophallus synandrifer

Declining

Overview

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

Amorphophallus synandrifer faces severe population decline due to extensive deforestation and agricultural conversion of its native lowland forest habitat in Sumatra. The species' extremely restricted range makes it particularly vulnerable to habitat fragmentation, while collection pressure for the horticultural trade has further reduced wild populations. Palm oil plantation expansion continues to eliminate remaining forest patches where this endemic aroid persists.

Threat summary

Habitat

This endemic Indonesian aroid inhabits the understory of lowland tropical rainforests in Sumatra, typically growing in shaded areas with rich, well-drained soils. The species requires the humid microclimate and specific soil conditions found in primary and mature secondary forest environments.
