When Eurasian watermilfoil infests a body of water, it is able to reproduce and spread very quickly. The invasive species overcrowds the body of water, takes resources from native plants, and diminishes the population of native plants. When there are less native plants that the native animals need for food and cover, the native animals begin to struggle and diminish as well. As the invasive Eurasian watermilfoil thrives, it engulfs the body of water, and there are less sandy or gravelly areas that certain fish need to spawn. If Eurasian watermilfoil takes over a body of water, the native plants and animals may begin to die
