Algernonia brasiliensis

Declining

Overview

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

Algernonia brasiliensis faces severe pressure from ongoing deforestation and agricultural expansion throughout its Atlantic Forest range in southeastern Brazil. The species' specialized habitat requirements make it particularly vulnerable to forest fragmentation, as remaining populations become isolated in small forest patches. Mining activities and urban development further reduce available habitat, while the species' limited dispersal ability prevents recolonization of degraded areas.
