Aquatic Invasive Species
Imagine your favorite fishing spot and the wonderful memories. Things may look fine but underneath the surface there is a serious threat. Everything you remembered is now cemented together in a sharp, smelly mess. Invaders have wiped out the fish species you used to catch. Aquatic invasive species are not native to an ecosystem. Their introduction causes, or is likely to cause, harm to the economy, the environment, or to human health. Aquatic invasive species are a growing risk to parks and their values. In the United States alone, there are more than 250 non-native aquatic species. For many centuries, humans have contributed to spreading non-native species around the globe. You can make a difference. To learn more about Aquatic Invasive Species in the National Park Service, visit the Fish & Fishing website.
