Rinorea ramiziana

Declining

Overview

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

Rinorea ramiziana faces severe pressure from deforestation and agricultural expansion across 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 ecological specialization limits its ability to adapt to degraded environments.

Threat summary

Habitat

This species is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, occurring in humid lowland and montane forests. It typically grows in the understory of primary and well-preserved secondary forests, preferring areas with rich, well-drained soils.
