Ololygon peixotoi

Declining

Overview

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

Ololygon peixotoi faces severe threats from rapid deforestation and agricultural expansion within its extremely limited range in Brazil's Atlantic Forest. The species' small population size and restricted distribution make it particularly vulnerable to habitat fragmentation, while climate change poses additional risks to its specialized microhabitat requirements. Urban development and infrastructure projects continue to encroach upon remaining forest patches where this critically endangered frog persists.

Threat summary

Habitat
