Wallenia sylvestris

Unknown

Overview

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

Wallenia sylvestris faces severe pressure from deforestation and habitat conversion throughout its limited range in Puerto Rico's montane forests. The species is particularly vulnerable to hurricane damage, which can devastate entire populations in single events, as demonstrated by recent major storms. Agricultural expansion and urban development continue to fragment the remaining forest patches where this endemic tree survives.

Threat summary

Habitat

Wallenia sylvestris is endemic to the montane rainforests of Puerto Rico, typically found in wet limestone forests and cloud forests at elevations between 300-900 meters. The species requires the humid, shaded understory conditions characteristic of mature tropical montane forest ecosystems.
