Scolosanthus acunae

Unknown

Overview

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

Scolosanthus acunae faces severe threats from habitat destruction due to agricultural expansion and urban development in its limited Cuban range. The species' extremely restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its native forest fragments. Climate change poses additional risks through altered precipitation patterns that could affect the specific microhabitat conditions this endemic shrub requires.
