Springs-Dependent Species

Springs in the Grand Canyon are hotspots of biological diversity; places where life is highly concentrated and the taxa include upland, riparian, wetland, and aquatic species found only at springs for part or all of their life cycles. Some SDSs, such as many hydrobiid springsnails and desert pupfish (Cyprinodontidae) occur only in springs sources and outflows, while some dragonflies, aquatic true bugs, tiger and diving beetles, crane and shore flies, amphibians, fish, and other vertebrates require springs for spawning and/or larval rearing habitat, or for over-wintering or winter dormancy.
