Overview

Duttaphrynus noellerti is a critically endangered toad species endemic to the Western Ghats of India, specifically found in the state of Kerala. This amphibian belongs to the Asian toad genus Duttaphrynus and represents one of the most threatened anuran species in the region. The species inhabits tropical montane forests at moderate to high elevations, where it depends on specific microhabitat conditions including adequate moisture levels and forest canopy cover.

Like many amphibians in the Western Ghats biodiversity hotspot, D. noellerti faces severe population declines due to multiple anthropogenic pressures. Habitat destruction and fragmentation from agricultural expansion, urbanization, and infrastructure development constitute the primary threats to its survival.

The species' restricted range makes it particularly vulnerable to environmental changes, as populations have limited opportunities for dispersal to suitable alternative habitats. Climate change poses additional risks through altered precipitation patterns and temperature regimes that may disrupt breeding cycles and habitat suitability. The fungal disease chytridiomycosis, which has devastated amphibian populations globally, represents another potential threat to remaining populations.

Conservation efforts for this species remain limited, though it occurs within some protected areas of the Western Ghats. Effective conservation requires immediate habitat protection, restoration of degraded forest areas, and comprehensive population monitoring. Research into the species' specific ecological requirements and breeding biology is essential for developing targeted conservation strategies to prevent extinction.

Duttaphrynus noellerti faces severe threats from habitat destruction and fragmentation caused by agricultural expansion, urbanization, and infrastructure development within its restricted range in Kerala's Western Ghats. Climate change and potential fungal diseases further threaten the remaining populations of this critically endangered toad.

Frequently asked questions

Why is Noellert's Toad classified as Critically Endangered?
Noellert's Toad 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. Duttaphrynus noellerti faces severe threats from habitat destruction and fragmentation caused by agricultural expansion, urbanization, and infrastructure development within its restricted range in Kerala's Western Ghats. Climate change and potential fungal diseases further threaten the remaining populations of this critically endangered toad.
Where does Noellert's Toad live?
Noellert's Toad occurs in Sri Lanka. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Noellert's Toad?
The main threats to Noellert's Toad are 11.1, 2.1, 5.3, and 5.4. The full IUCN-classified threat record for this species is detailed on the species page.
