Vernal pools, or seasonal pools, are a unique type of wetland habitat. They are typically small, shallow, ephemeral water bodies, and unlike a pond or a lake, they have no permanent inlet or outlet. They are filled each spring by rain and snow melt, then dry up for a period of time during the summer. These qualities of vernal pools distinguish them from other wetlands, and they support several species of animals that require these temporary wetland habitats for survival.
