Muellera variabilis

Declining

Overview

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

Muellera variabilis faces severe pressure from agricultural expansion and cattle ranching across its limited range in Brazil's Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Urban development and infrastructure projects continue to encroach on the species' remaining forest patches, while selective logging targets mature trees of this valuable timber species.

Threat summary

Habitat

This leguminous tree species inhabits remnant Atlantic Forest fragments in southeastern Brazil, typically growing in humid lowland and montane forests. It occurs in both primary and secondary forest formations, often found along forest edges and in partially disturbed areas where it can tolerate moderate canopy openness.

Frequently asked questions

Why is Muellera variabilis classified as Endangered?
Muellera variabilis is classified as Endangered — facing a very high risk of extinction in the wild — because population numbers are declining steeply and key habitats are under sustained pressure. Muellera variabilis faces severe pressure from agricultural expansion and cattle ranching across its limited range in Brazil's Atlantic Forest region. Habitat fragmentation has isolated remaining populations, reducing genetic diversity and limiting natural regeneration. Urban development and infrastructure projects continue to encroach on the species' remaining forest patches, while selective logging targets mature trees of this valuable timber species.
Where does Muellera variabilis live?
Muellera variabilis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Muellera variabilis?
The main threats to Muellera variabilis are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
