Aquatic Invasive Species
Each year, Pennsylvania residents pay millions of dollars to identify, prevent, eradicate, and control invasive species. Pennsylvania’s diverse geography is home to thousands of different plant, animal, and invertebrate species. Unfortunately, not all of these organisms are beneficial. Pennsylvania’s natural resources and economy are threatened by unwanted invaders that threaten our native plants and wildlife by outcompeting with them for resources and habitat.
Aquatic Invasive Species (AIS) are non-native plants, animals, or pathogens that cause harm to the environment, the economy, native species, and human or animal health. Preventing their spread is important because once introduced, these species disrupt ecosystems, reduce biodiversity, and result in lost time, resources, and revenue for communities.
Aquatic invasive species can be introduced unintentionally through transport of ballast water in cargo ships, through water-related activities like boating and fishing. They can also be transported to new locations by activities such as releasing unwanted aquarium pets or dumping live bait into a waterway or lake. No matter how they arrive, invasive species can wreak havoc and impact entire ecosystems.
Pennsylvania Sea Grant develops outreach-related materials, delivers in-person and virtual trainings, and collaborates with state, regional, federal, and inter-jurisdictional partners to help stop the spread of aquatic invasive species.
