With the first frost-free and rainy nights in late winter, frogs, toads and newts awaken from their hibernation and make their way to their spawning waters in their thousands. Depending on the weather and region, the first animals are already on the move in mid-February.

Mass migrations of amphibians usually take place a few weeks later. In a press release issued on Thursday, the Swiss Society for the Protection of Animals (STS) therefore called on motorists to drive at reduced speed on endangered roads from February to April or to avoid sections of road used by amphibians.

Common toads, grass frogs, alpine newts and the like often travel several kilometers after the winter break and frequently have to cross roads to reach their breeding grounds. Many amphibians are run over in the process.

According to the animal welfare organization, common toads are the most endangered. This is because the entire population starts moving at the same time and the animals also travel very slowly. They sometimes need 15 to 20 minutes to cross a road. But grass frogs and newts also often migrate in their hundreds.

All native amphibian species are protected throughout Switzerland.
