Algernonia dimitrii

Declining

Overview

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

Algernonia dimitrii faces severe threats from deforestation and habitat fragmentation in its restricted range within the Atlantic Forest of southeastern Brazil. Mining activities and agricultural expansion have eliminated much of its original forest habitat, while the remaining fragments are too small to support viable populations. Climate change poses an additional threat through altered precipitation patterns that affect the humid microhabitats this species requires.
