Pristimantis signifer

Declining

Overview

Pristimantis signifer is a species of frog in the family Strabomantidae.

Pristimantis signifer faces severe population decline due to habitat destruction from agricultural expansion and urban development in its restricted Andean range. The species is particularly vulnerable to climate change impacts, as rising temperatures force populations to higher elevations with increasingly limited suitable habitat. Chytrid fungal disease has devastated amphibian populations throughout the region, posing an additional critical threat to remaining populations.

Threat summary

Habitat

This species inhabits cloud forests and montane humid forests in the Andes, typically found in leaf litter and low vegetation between 1,800-2,800 meters elevation. It requires pristine forest conditions with high humidity and stable microclimates for breeding and survival.

Frequently asked questions

Why is Pristimantis signifer classified as Critically Endangered?
Pristimantis signifer 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 signifer faces severe population decline due to habitat destruction from agricultural expansion and urban development in its restricted Andean range. The species is particularly vulnerable to climate change impacts, as rising temperatures force populations to higher elevations with increasingly limited suitable habitat. Chytrid fungal disease has devastated amphibian populations throughout the region, posing an additional critical threat to remaining populations.
Where does Pristimantis signifer live?
Pristimantis signifer 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 signifer?
The main threats to Pristimantis signifer are 1.1, 2.1, 4.1, and 8.1. The full IUCN-classified threat record for this species is detailed on the species page.
