Wild Common Frog UK Population

Common frogs are declining in parts of the UK due to habitat loss, disease, and garden pond loss. Understanding their needs helps conservation.

Key Facts

Common frogs are the most widespread UK amphibian but have declined in some areas
Garden ponds are the most important breeding habitat for common frogs
Ranavirus disease causes mass mortality events in some frog populations
Frogs are tolerant of cold and can survive freezing of surrounding water
Spawn is vulnerable to late frost events that are becoming more unpredictable with climate change

Welfare Considerations

Frogs affected by ranavirus disease experience rapid tissue breakdown and death - a significant welfare harm. Habitat loss forcing frogs to travel further between habitats increases road mortality. Climate-driven spawn freeze events kill developing embryos. Garden pond creation and maintenance is the single most impactful action for individual frog welfare.

What You Can Do

Create or maintain a garden pond for frog breeding habitat
Report frog mass mortality events to the Garden Wildlife Health project
Avoid introducing fish to wildlife ponds as they eat frog spawn and tadpoles
