Leandra cogniauxiana

Declining

Overview

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

Leandra cogniauxiana faces severe pressure from ongoing deforestation and habitat fragmentation within Brazil's Atlantic Forest, one of the world's most threatened biodiversity hotspots. Agricultural expansion, particularly cattle ranching and crop cultivation, continues to reduce and isolate the remaining forest patches where this endemic shrub survives. Urban development and infrastructure projects further fragment its already limited range, while the species' apparent narrow ecological requirements make it particularly vulnerable to these landscape-level changes.

Threat summary

Habitat

This endemic Brazilian shrub inhabits the understory and edges of Atlantic Forest remnants, typically in humid montane and submontane forests. It appears to favor areas with well-drained soils and partial shade conditions characteristic of secondary forest growth and forest margins.
