Mahonia oiwakensis

Unknown

Overview

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

Mahonia oiwakensis faces significant pressure from habitat degradation in Taiwan's montane forests, where agricultural expansion and infrastructure development have fragmented its natural range. The species' restricted distribution makes it particularly vulnerable to localized disturbances, while climate change poses additional risks by altering the cool, humid conditions essential for its survival. Collection pressure for horticultural trade has also contributed to population declines in accessible areas.

Threat summary
