Polyscias dichroostachya

Unknown

Overview

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

Polyscias dichroostachya faces severe pressure from deforestation and agricultural expansion across its limited range in tropical Africa. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while its slow growth rate hampers natural recovery. Logging activities targeting both the species itself and surrounding forest canopy have significantly reduced population numbers over recent decades.

Threat summary

Habitat

This species inhabits lowland and montane tropical rainforests, typically found in the understory and forest edges at elevations between 200-1,500 meters. It prefers well-drained soils in areas with consistent moisture and partial shade provided by the forest canopy.
