Polycarpaea hassalensis

Unknown

Overview

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

Polycarpaea hassalensis faces severe pressure from habitat degradation on its restricted island range. Urban development and agricultural expansion have fragmented the coastal and lowland areas where this endemic plant occurs. Invasive plant species compete directly with native vegetation, while tourism infrastructure development continues to reduce available habitat. The species' limited distribution makes it particularly vulnerable to localized disturbances and extreme weather events.
