In spring water accumulates in the lanes on roads without foundation and in small depressions of ground. Today such roads and little used roads are rarely to be found.

Shortly frogs, toads and insects settle in the small puddles, where they can take care of their survival till the waters dry up.

Lots of species adapted themselves to this special rhythm of short-term supplies of food and living space. So they have found their ecological niches,

The calls of some species of amphibians, that live there, are to be heard over a long distance and serve to find their partners and to distinguish their territory.

The Yellow bellied toad depends on these open, continually renewing living spaces. They are hardly to be found even in small puddles because of their little size and because of the colour of their top, which suits to the soil.

In Thuringia it reaches its northern expansion border. It has its numerical highest occurence in Germany on a former military training ground in the west of the Thuringian Basin.
