Hieronima crassistipula

Unknown

Overview

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

Hieronima crassistipula faces severe population decline primarily due to extensive deforestation and habitat conversion for agricultural expansion in its limited Costa Rican range. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction, while its slow growth rate as a canopy tree limits natural recovery potential. Climate change poses additional pressure through altered precipitation patterns affecting the humid forest conditions this species requires.

Threat summary

Habitat

This species inhabits humid lowland and premontane forests of Costa Rica, typically occurring in primary forest canopies at elevations between 50-800 meters. It requires well-drained soils and consistent moisture levels characteristic of tropical wet forest ecosystems.
