Invasive Species in Pennsylvania
Invasive species are those plants, animals and pathogens that are not native to an area and can cause harm to the environment, to the economy and to human health. While not all non-native species are invasive, some can really do damage to our public and private lands. Invasive species are highly adaptable to different habitats, grow quickly or reproduce abundantly, are difficult to eradicate and can negatively impact our native species.
