NATURA 2000 - species and habitats

The yellow-bellied toad could be said to be a pioneer species, given that it quickly discovers and utilises any newly-created spawning ponds. It prefers primarily small, shallow areas of water exposed to sunshine, in which the water warms up quickly. Young animals’ high mobility favours spontaneous occupation of newly emerging habitat areas. The lack of pioneer biotopes favoured by the yellow-bellied toad is a strong threat to stocks of this species.
