Croton thomasii

Unknown

Overview

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

Croton thomasii faces severe pressure from agricultural expansion and urban development across its limited range in the Caribbean. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while invasive plant species compete for resources in its native ecosystems. Climate change poses an additional threat through altered precipitation patterns and increased storm intensity affecting its specialized habitat requirements.

Threat summary
