Byttneria minytricha

Unknown

Overview

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

Byttneria minytricha faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Atlantic Forest of Brazil. Agricultural expansion, particularly cattle ranching and sugarcane cultivation, continues to reduce the remaining forest patches where this species occurs. Urban development pressures and infrastructure projects further fragment the already restricted habitat, isolating small populations and reducing genetic diversity.

Threat summary

Why is Byttneria minytricha classified as Critically Endangered?
Byttneria minytricha is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Byttneria minytricha faces severe threats from ongoing deforestation and habitat fragmentation within its extremely limited range in the Atlantic Forest of Brazil. Agricultural expansion, particularly cattle ranching and sugarcane cultivation, continues to reduce the remaining forest patches where this species occurs. Urban development pressures and infrastructure projects further fragment the already restricted habitat, isolating small populations and reducing genetic diversity.
Where does Byttneria minytricha live?
Byttneria minytricha 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 Byttneria minytricha?
The main threats to Byttneria minytricha 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.
