Marcgraviastrum gigantophyllum

Unknown

Overview

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

Marcgraviastrum gigantophyllum faces primary threats from deforestation and habitat fragmentation across its limited range in the Atlantic Forest of southeastern Brazil. Agricultural expansion, particularly cattle ranching and sugarcane cultivation, continues to reduce and isolate remaining forest patches where this endemic tree species occurs. The species' restricted distribution and specialized habitat requirements make it particularly vulnerable to ongoing forest conversion pressures.
