Lamanonia ulei

Declining

Overview

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

Lamanonia ulei faces severe pressure from ongoing deforestation and habitat fragmentation across its limited range in Brazil's Atlantic Forest. Agricultural expansion, particularly cattle ranching and soybean cultivation, continues to reduce and isolate remaining forest patches where this endemic tree species occurs. The species' restricted distribution makes it particularly vulnerable to localized habitat destruction and edge effects from surrounding cleared areas.
