Salzmannia arborea

Declining

Overview

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

Salzmannia arborea faces severe pressure from deforestation and agricultural expansion throughout its limited range in Brazil's Atlantic Forest. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Urban development and cattle ranching continue to reduce the quality and connectivity of its forest habitat, while climate change may alter the specific microhabitat conditions this tree species requires.
