Joosia oligantha

Unknown

Overview

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

Joosia oligantha faces significant pressure from habitat degradation in its restricted range within the Atlantic Forest of southeastern Brazil. Deforestation for agriculture and urban expansion continues to fragment the remaining forest patches where this endemic species occurs. The species' limited distribution makes it particularly vulnerable to localized threats, with small population sizes increasing extinction risk from stochastic events.
