Overview

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

The Moor Frog faces severe population declines across its European range due to widespread wetland drainage and agricultural intensification. Climate change poses an additional threat by altering the hydrological cycles of its breeding habitats, while habitat fragmentation isolates remaining populations and reduces genetic diversity. Urban development continues to eliminate critical breeding sites, particularly in lowland areas where human pressure is greatest.

Threat summary

Habitat

The Moor Frog inhabits acidic wetlands, peat bogs, heathlands, and shallow pools across northern and central Europe. It requires permanent or semi-permanent water bodies for breeding, typically favoring acidic conditions with pH levels between 4.5-7.0.

Frequently asked questions

Why is Moor Frog classified as Vulnerable?
Moor Frog is classified as Vulnerable because the population is declining and the species faces a high risk of extinction in the medium-term future if current pressures continue. The Moor Frog faces severe population declines across its European range due to widespread wetland drainage and agricultural intensification. Climate change poses an additional threat by altering the hydrological cycles of its breeding habitats, while habitat fragmentation isolates remaining populations and reduces genetic diversity. Urban development continues to eliminate critical breeding sites, particularly in lowland areas where human pressure is greatest.
Where does Moor Frog live?
Moor Frog occurs in Åland Islands, Algeria, Angola, Austria, Belarus, and Belgium (plus 33 other countries). Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
What are the main threats to Moor Frog?
The main threats to Moor Frog are ai-1, ai-2, ai-3, and ai-4. The full IUCN-classified threat record for this species is detailed on the species page.
