Pennsylvania is home to numerous invasive plants, insects, birds, mammals and fish. Some, like multiflora rose, can be found statewide while others, like round goby and wild boar, have limited ranges (at least for now). These invaders entered Pa. by many means—in boat ballast water, as fishing bait, in the soil of nursery plants, in firewood, and on the soles of hikers’ shoes. Their impact on the state’s wildlife and habitats varies but one thing is the same for all invasive species; by definition they have the ability to cause harm to the environment, to the economy or to human health. Learn to identify a few key invaders in your area, find out how to prevent their spread and do your part to protect our native plants and animals.
