Wetland biotopes found in quarries are primarily formed by species of reed, tall perennial herb, and willow groves. Besides numerous species of snail, dragonfly, amphibian, and other insects, they offer breeding sites and sufficient food for specific bird species. Often concealed, ponds are particularly suitable homes for dragonflies and amphibians such as Yellow-bellied Toad, Warty Newt, and European Toad. Lakes act as a resting place and hunting site for birds such as Cormorants, Grey Herons and the Common Tern.
