A big deal in Germany The amphibian migration - called Krötenwanderung - is a big deal in Germany. In spring and fall roads are blocked completely for weeks or for several hours at day and/or night. Some roads are closed during the whole year. There are toad tunnels built under roads especially for migratory amphibians. In spring and fall toad fences are built on the sides of toads busy roads with buckets every few meters embedded (?) in the ground. The toads fall into these buckets when they go along the fences, looking for a hole in the fence so that they can cross the street . Volunteers checking the buckets every few hours and carrying the amphibians across the street. Every spring and fall articles in community newsletters calling the community members for checking basement wells and the like on fallen into toads and that the wells and the like best be covered forever because of the peril for the toads.
