Cardioglossa trifasciata

Declining

Overview

Cardioglossa trifasciata is a species of frog in the family Arthroleptidae. It is endemic to western Cameroon and only known from the southern slopes of Mount Manengouba. The common names Nsoung long-fingered frog and Banded long-fingered frog have been coined for it.

Cardioglossa trifasciata faces severe population decline primarily due to extensive deforestation and agricultural expansion within its extremely limited range in Cameroon's montane forests. Mining activities and infrastructure development have further fragmented the remaining suitable habitat, while climate change threatens to shift the temperature and moisture conditions essential for this high-altitude specialist. The species' restricted distribution makes it particularly vulnerable to any habitat disturbance within its small geographic range.

Threat summary

Habitat

This species inhabits montane forests at elevations between 1,200-2,000 meters in the Cameroon Highlands, particularly favoring areas with dense leaf litter and high humidity. It is typically found in primary and secondary forest environments with adequate moisture retention and stable microclimatic conditions.

Frequently asked questions

Why is Cardioglossa trifasciata classified as Critically Endangered?
Cardioglossa trifasciata 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. Cardioglossa trifasciata faces severe population decline primarily due to extensive deforestation and agricultural expansion within its extremely limited range in Cameroon's montane forests. Mining activities and infrastructure development have further fragmented the remaining suitable habitat, while climate change threatens to shift the temperature and moisture conditions essential for this high-altitude specialist. The species' restricted distribution makes it particularly vulnerable to any habitat disturbance within its small geographic range.
Where does Cardioglossa trifasciata live?
Cardioglossa trifasciata occurs in Cameroon, and Nigeria. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Cardioglossa trifasciata?
The main threats to Cardioglossa trifasciata are 11.1, 2.1, 2.3, and 5.3. The full IUCN-classified threat record for this species is detailed on the species page.
