Symplocos rizzinii

Declining

Overview

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

Symplocos rizzinii faces severe threats from deforestation and habitat conversion in its restricted range within the Atlantic Forest of Brazil. The species' extremely limited distribution makes it particularly vulnerable to local extinctions from agricultural expansion and urban development. Mining activities and infrastructure development pose additional pressures on the remaining forest fragments where this endemic tree persists.
