Dulacia crassa

Unknown

Overview

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

Dulacia crassa faces mounting pressure from agricultural expansion and cattle ranching across its Atlantic Forest range in southeastern Brazil. Habitat fragmentation has isolated remaining populations, while selective logging targets the mature forest canopy where this tree species thrives. Urban development along Brazil's coastal regions continues to reduce available habitat, particularly affecting lowland forest areas where the species is most abundant.
