Appunia aurantiaca

Declining

Overview

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

Appunia aurantiaca faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Atlantic Forest of southeastern Brazil. Mining activities and urban development have fragmented remaining forest patches, isolating populations and reducing genetic diversity. The species' specialized habitat requirements make it particularly vulnerable to edge effects and microclimate changes in degraded forest fragments.

Frequently asked questions

Why is Appunia aurantiaca classified as Endangered?
Appunia aurantiaca 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. Appunia aurantiaca faces severe pressure from deforestation and agricultural expansion throughout its limited range in the Atlantic Forest of southeastern Brazil. Mining activities and urban development have fragmented remaining forest patches, isolating populations and reducing genetic diversity. The species' specialized habitat requirements make it particularly vulnerable to edge effects and microclimate changes in degraded forest fragments.
Where does Appunia aurantiaca live?
Appunia aurantiaca 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 Appunia aurantiaca?
The main threats to Appunia aurantiaca 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.
