PondNet Spawn Survey

Mapping amphibian breeding activity across the UK

The 2025 PondNet Spawn Survey is now open until May 2025. You can log your Common Toad and Common Frog spawn sightings using the form below to help us to better understand when are where frogs and toads are breeding across the UK. For a map of all records to date, visit the WaterNet data hub.

About the PondNet Spawn Survey

The PondNet Spawn Survey maps the sightings of Common Frog and Common Toad spawn across the country to better understand how amphibians use different types of waterbodies to breed.

Freshwater Habitats Trust runs the PondNet Spawn survey from December to May. With your help, we can collect important data on the location of breeding frogs and toads. To take part, record Common Frog or Common Toad spawn spotted in garden ponds or any ponds, ditches or puddles you come across in your adventures in the countryside. We’d also love you to share your sighting on social media, using the hashtag #SpawnSurvey
