Unonopsis sanctae-teresae

Unknown

Overview

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

Unonopsis sanctae-teresae faces severe threats from deforestation and agricultural expansion in its limited range within the Atlantic Forest of Brazil. The species' extremely restricted distribution makes it particularly vulnerable to habitat fragmentation, as even small-scale forest clearance can eliminate entire subpopulations. Mining activities and urban development in the region pose additional pressures on the remaining forest fragments where this rare tree persists.
