The European green toad can easily be identified by its characteristic pattern of distinctly outlined green spots on a whitish, grey or brownish background. These toads populate dry and warm habitats featuring only little vegetation such as mining pits, ruderal sites, railway embankments and dry grassland.
Diverse water bodies, varying from small pools to great lakes, can serve as acceptable spawning grounds. Their common characteristic is a shallow water area with only sporadic vegetation - or none at all. Beside the general loss of water bodies, the European green toad is threatened also by the emergence of dense vegetation at their spawning grounds and summer habitat. Shortly after the cessation of business activities, mining pits, for example, often no longer qualify unless frequent management measures are undertaken.
