Two wild Konik horses in the dunes at the edge of a seep. Two horses drinking the water of seep, a little dune lake in a moist dune valley. A seep is a moist or wet place where water, usually groundwater, reaches the earth's surface from an underground aquifer. Large herbivores are brought back into the Dutch nature reserves and live in the wild, to help maintain the natural eco-systems.
