Pleodendron macranthum

Declining

Overview

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

Pleodendron macranthum faces severe threats from deforestation and habitat conversion in Puerto Rico's remaining montane forests. The species' extremely limited range makes it vulnerable to localized disturbances, while invasive plant species compete for resources in its native cloud forest habitat. Hurricane damage and climate-induced changes to precipitation patterns further threaten the specialized moisture-dependent ecosystem this endemic tree requires.

Threat summary

Habitat

This endemic tree species inhabits Puerto Rico's montane cloud forests, typically found in moist, high-elevation areas with consistent fog and precipitation. It grows in the understory and canopy gaps of these specialized tropical montane ecosystems.
