Simira walteri
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Simira walteri faces severe pressure from ongoing 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. Urban development and infrastructure projects further compound habitat loss, while the species' apparent rarity and restricted distribution make it particularly vulnerable to local extinctions from small-scale disturbances.
Habitat
Simira walteri is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, occurring in remnant patches of tropical moist forest. This species typically grows in the understory and canopy of primary and secondary forest formations within this highly threatened biodiversity hotspot.
