Schumacheria alnifolia

Unknown

Overview

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

Schumacheria alnifolia faces severe population decline due to extensive deforestation and habitat conversion throughout its limited range in Sri Lanka's wet zone forests. The species is particularly vulnerable to logging operations and agricultural expansion, as it requires intact forest canopy conditions. Climate change poses an additional threat through altered precipitation patterns affecting the moist forest ecosystems this endemic tree depends upon.
