Why protect Pennsylvania’s native species?
Pennsylvania is home to diverse native plants, trees, insects, fish, birds, and mammals that originated thousands of years ago and thrive in mutual dependence. This native ecosystem provides us with natural resources that benefit our lives by enabling agricultural food production, recreation, fisheries, timber, and more.
As humans have increased worldwide commerce and travel, nonnative species have crisscrossed the world with us. When species are transported to areas outside their native range, they have no natural predators. They often invade, crowding out and threatening the survival of native species.
The council created Pennsylvania Native Species Day to celebrate the state’s diverse native species and increase Pennsylvanians’ understanding of the importance of protecting them against the proliferation of invasive species.
