Portulaca cubensis

Unknown

Overview

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

Portulaca cubensis faces severe threats from urban development and coastal infrastructure expansion across its extremely limited Cuban range. The species' restriction to specific coastal and rocky habitats makes it particularly vulnerable to habitat modification and fragmentation. Tourism development and sea-level rise pose additional pressures on the remaining populations of this endemic succulent.
