The ponds start as trapped pockets of lake water and can erode away or be filled by wind-blown sand or drifting dunes.[44] The new ponds provide habitat for plants and animals: for example, the state park is home to 89 species of Odonata (dragonflies and damselflies) and Lepidoptera, including 35 different butterflies, as well as 84 different sorts of spiders.[5][42]
