Overview

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

Calophyllum walkeri faces severe pressure from deforestation and habitat conversion throughout its native range in Sri Lanka's wet zone forests. The species is particularly vulnerable to logging operations targeting its valuable timber, as Calophyllum species are prized for construction and furniture making. Agricultural expansion and urban development continue to fragment the remaining forest patches where this endemic tree occurs.
