Alternanthera flavicoma

Unknown

Overview

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

Alternanthera flavicoma faces severe pressure from agricultural expansion and urban development across its limited range in southeastern Brazil. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, while invasive plant species compete for resources in its native cerrado and Atlantic Forest edge habitats. Climate change poses an additional threat through altered precipitation patterns that could disrupt the seasonal flooding cycles this species depends upon.

Threat summary

Habitat
