Casasia acunae

Unknown

Overview

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

Casasia acunae faces severe threats from habitat destruction due to urban development and agricultural expansion across its extremely limited range in Cuba. The species' 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.

Threat summary

Habitat

Casasia acunae is endemic to Cuba where it inhabits dry coastal forests and scrublands, typically growing in limestone-derived soils. The species occurs in fragmented forest patches at low elevations, often in areas transitioning between coastal vegetation and inland dry forests.
