Aspidosperma thomasii

Declining

Overview

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

Aspidosperma thomasii faces severe pressure from deforestation and habitat fragmentation across its limited range in the Atlantic Forest of southeastern Brazil. The species is particularly vulnerable due to its slow growth rate and specific soil requirements, making population recovery extremely difficult once local populations are eliminated. Selective logging for its valuable timber and conversion of forest areas to agriculture and urban development continue to reduce available habitat.
