Aquatic Conservation

Invertebrates live in every type of aquatic habitat, from streams and seeps to marshes and lakes. Aquatic invertebrates such as stoneflies, mayflies, mussels, and midges play critical roles in sustaining healthy aquatic ecosystems, and are at the center of the aquatic food web. The winged adult forms of many aquatic insects also provide a huge amount of the food for terrestrial birds, bats, and reptiles. Aquatic invertebrates and the habitats that sustain them are seriously imperiled. In the United States, over half of the wetlands that existed in the 1600s have been lost, and a recent nationwide stream survey found pesticides or their degradates in all the streams sampled. The Aquatic Conservation program works to protect aquatic invertebrates and the ecosystems that sustain them.
