Lacunaria sampaioi

Declining

Overview

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

Lacunaria sampaioi faces severe pressure from 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. Urban development and infrastructure projects further fragment the species' already restricted habitat, while climate change may alter the specific microhabitat conditions this endemic species requires.

Threat summary

Habitat

This species is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, inhabiting humid lowland and montane forests. It typically occurs in areas with dense canopy cover and specific microhabitat requirements within the remaining forest fragments.
