Swartzia alternifoliolata

Declining

Overview

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

Swartzia alternifoliolata faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Atlantic Forest of Brazil. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and urban development further reduce available habitat, while the species' apparent rarity suggests low population resilience to ongoing environmental pressures.
