Pellacalyx yunnanensis

Unknown

Overview

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

Pellacalyx yunnanensis faces severe pressure from rapid deforestation and agricultural expansion across its limited range in Yunnan Province, China. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while logging operations and conversion of forest land to rubber plantations have significantly reduced suitable growing areas. Climate change poses an additional threat through altered precipitation patterns that may affect the specific moisture conditions this species requires.
