Marcgraviastrum gigantophyllum
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.
Habitat
This endemic tree species inhabits remnant Atlantic Forest fragments in southeastern Brazil, typically occurring in humid montane and submontane forests at elevations between 500-1200 meters. It requires well-drained soils and the specific microclimate conditions found in mature forest understory and canopy gaps.
