Pennsylvania’s natural resources and economy are threatened by unwanted invaders – non-native invasive species.

Non-native invasive species are constantly making their way into Pennsylvania. These invaders are found on the land and in our waters, and are often introduced through the everyday, unintentional activities of citizens. They can be introduced through the transport of firewood, boats and fishing gear, and through other outdoor activities that began in one area (which may be native for that species) and become unintentional 'hitch-hikers' into another region where they can cause great harm to native species. Non-native species can also be introduced through natural processes and are sometimes intentionally introduced by humans. 

However they arrive, once established they have the potential to change Pennsylvania forever. Non-native invasive species are a threat to Pennsylvania’s economy and environment. Commonwealth citizens pay millions of dollars to prevent, eradicate, and control invasive species each year. These invaders threaten our native wildlife and plants by out-competing them for resources and habitat.

Invasive species in Pennsylvania can be split into two categories: aquatic invasive species and terrestrial invasive species. PA Sea Grant participates in several projects related to education, outreach, research, control, and management of these invasive species.
