Muellera crucisrubierae

Declining

Overview

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

Muellera crucisrubierae faces severe pressure from deforestation and agricultural expansion across its limited range in the Atlantic Forest of Brazil. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and urban development further compound these pressures, reducing the quality and connectivity of suitable habitat.

Threat summary

Habitat

This leguminous tree species is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, occurring in humid montane and submontane forests. It typically grows in well-drained soils on slopes and ridges within the highly biodiverse but severely fragmented Atlantic Forest biome.

Frequently asked questions

Why is Muellera crucisrubierae classified as Endangered?
Muellera crucisrubierae 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 crucisrubierae faces severe pressure from deforestation and agricultural expansion across its limited range in the Atlantic Forest of Brazil. The species' restricted distribution makes it particularly vulnerable to habitat fragmentation, as remaining forest patches become increasingly isolated. Mining activities and urban development further compound these pressures, reducing the quality and connectivity of suitable habitat.
Where does Muellera crucisrubierae live?
Muellera crucisrubierae occurs in Venezuela. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Muellera crucisrubierae?
The main threats to Muellera crucisrubierae 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.
