Scolosanthus roulstonii

Declining

Overview

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

Scolosanthus roulstonii faces severe threats from habitat destruction due to urban development and agricultural expansion across its limited range in the Caribbean. The species' restricted distribution makes it particularly vulnerable to localized disturbances, while invasive plant species compete for resources in its native forest habitats. Climate change poses additional risks through altered precipitation patterns and increased storm intensity affecting the delicate forest ecosystems where this endemic species occurs.
