Ruda

Plethadenia cubensis

Unknown

Overview

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

Plethadenia cubensis faces severe pressure from habitat destruction as Cuba's remaining natural forests are cleared for agriculture and urban development. The species' limited distribution makes it particularly vulnerable to localized environmental changes, while invasive plant species alter the understory composition of its forest habitat. Climate change poses an additional threat through altered precipitation patterns that could affect the humid microhabitats this endemic species requires.

Threat summary

Habitat

This Cuban endemic inhabits humid montane forests and shaded woodland understories, typically found in areas with consistent moisture and dense canopy cover. The species shows preference for undisturbed forest environments with rich organic soil layers and stable microclimatic conditions.
