Plants, animals, and other life forms have adapted to live and reproduce in aquatic habitats. Iowa’s waters are home to thousands of plant and animal species. This section provides a brief introduction to the different types found in our waters.
- Iowa’s Nature Series – Aquatic Environments – From the ephemeral pool of a prairie pothole to the giant pools of the mighty Mississippi, Iowa’s lands are defined by their diverse, and critically important aquatic ecosystems.
Aquatic plants are essential in aquatic ecosystems. They provide oxygen, food, shelter, and protect shorelines and stream banks from eroding. They have a variety of adaptations to living in, on or near water and are divided into several groups.
- Minnesota Department of Natural Resources: Aquatic Plants – Information about aquatic plants. Broken into groups – algae, emergent plants, floating-leaf plants, and submerged plants.
- Iowa Department of Natural Resources (DNR): Aquatic Invasive Plants – Pictures and descriptions of aquatic invasive plants (with pdf downloads).
- Iowa DNR: Aquatic Plants in Iowa Ponds – Detailed information about aquatic plants you will find in Iowa ponds. Includes recommendations for what to grow and what not to grow in farm ponds.
- Iowa’s Nature Series – Plants – From the bur oak tree towering over the savanna to the humble bladderwort, floating untethered in the water of wetlands, Iowa’s plants and plant-like organisms are fascinatingly diverse.
Invertebrates are the least conspicuous, but most abundant, animal group. They range in size from microscopic to larger than a baseball. Invertebrates found in Iowa waters range from freshwater sponges to worms and crustaceans (scuds, copepods, and crayfish), mollusks (mussels and snails), arachnids (spiders, ticks, and mites), and insects.
