Muellera grazielae

Declining

Overview

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

Muellera grazielae faces severe pressure from ongoing deforestation and agricultural expansion within its restricted range in Brazil's Atlantic Forest. The species' limited distribution makes it particularly vulnerable to habitat fragmentation, while cattle ranching and sugarcane cultivation continue to reduce available forest patches. Climate change poses additional stress through altered precipitation patterns affecting the humid forest conditions this legume requires.

Threat summary

Habitat

This endemic Brazilian legume inhabits remnant Atlantic Forest fragments, typically growing in humid lowland and submontane forests with rich, well-drained soils. The species requires the specific microclimate conditions found in mature forest understory environments.
