Overview

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

Pterostyrax psilophyllus faces severe population decline primarily due to habitat destruction from agricultural expansion and urban development across its limited range in East Asia. The species is particularly vulnerable to logging activities that target its preferred forest ecosystems, while climate change is altering the temperature and precipitation patterns essential for its survival. Additional pressure comes from overcollection for horticultural purposes, as this attractive flowering tree is sought after for ornamental plantings.

Threat summary
