Iowa DNR struggles to stop aquatic invasive species

The Iowa Department of Natural Resources is struggling to slow the spread of three invasive species: Eurasian milfoil, zebra mussels and silver carp.

Despite a $650,000 budget, the Iowa DNR’s team concentrating on stopping these invasive species has made little progress in their efforts. The Eurasian milfoil continues to spread to new lakes by attaching to boats, the zebra mussels are still moving upstream through Iowa’s rivers, and flooding has allowed the carp to move to new lakes.

Eurasian milfoil is an aquatic plant native to Europe, Asia and northern Africa. It competes against Iowa’s native aquatic plants, causing a decrease in diversity. The Zebra mussels are native to the Caspian Sea. They reproduce in mass quantities, compete with other aquatic life for food and kill native mussels. Silver carp are native to eastern Asia. Like the zebra mussels, they compete with native aquatic life for food.
