We are testing to see the diversity of aquatic macroinvertebrates at Caumsett State Park’s freshwater pond. Macroinvertebrates are vital to ecosystems, as they can create a healthy environment for other organisms. When there is a lack of invertebrates, environments and ecosystems can be harmed. We are also aware that macro invertebrates can cause bacterial and parasitic disease, so it is important to know the types of macro invertebrates in our local ecosystems.
