Pristimantis diogenes

Declining

Overview

Pristimantis diogenes is a species of frog in the family Strabomantidae. It is endemic to Colombia. Its natural habitats are tropical moist montane forests and rivers.

Pristimantis diogenes faces severe threats from rapid deforestation and agricultural expansion throughout its restricted Andean range. Mining activities and infrastructure development have fragmented its cloud forest habitat, while climate change is causing upslope shifts in suitable temperature and humidity conditions. The species' small population size and limited dispersal ability make it particularly vulnerable to local extinctions from habitat disturbance.

Threat summary

Habitat

This species inhabits montane cloud forests and humid upper montane forests in the Andes, typically at elevations between 2,000-3,000 meters. It requires areas with high humidity, dense vegetation cover, and stable microclimatic conditions for breeding and survival.

Frequently asked questions

Why is Pristimantis diogenes classified as Critically Endangered?
Pristimantis diogenes 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. Pristimantis diogenes faces severe threats from rapid deforestation and agricultural expansion throughout its restricted Andean range. Mining activities and infrastructure development have fragmented its cloud forest habitat, while climate change is causing upslope shifts in suitable temperature and humidity conditions. The species' small population size and limited dispersal ability make it particularly vulnerable to local extinctions from habitat disturbance.
Where does Pristimantis diogenes live?
Pristimantis diogenes occurs in Colombia. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Pristimantis diogenes?
The main threats to Pristimantis diogenes are 5.3, 8.1, ai-1, and ai-2. The full IUCN-classified threat record for this species is detailed on the species page.
