Algernonia kuhlmannii

Declining

Overview

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

Algernonia kuhlmannii faces severe threats 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 soy cultivation, continues to reduce the species' already limited range. Urban development and infrastructure projects further fragment remaining forest patches, isolating populations and reducing genetic diversity.

Threat summary

Habitat

This species is endemic to the Atlantic Forest (Mata Atlântica) of southeastern Brazil, occupying humid lowland and montane forest environments. It requires intact forest canopy and understory vegetation typical of this highly biodiverse but severely fragmented ecosystem.

Algernonia kuhlmannii faces severe threats 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 soy cultivation, continues to reduce the species' already limited range. Urban development and infrastructure projects further fragment remaining forest patches, isolating populations and reducing genetic diversity.
Where does Algernonia kuhlmannii live?
Algernonia kuhlmannii occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
