SPECIES OF PENNSYLVANIA

ENDANGERED SPECIES• An animal or plant species that has very

few organisms and can become extinct.

• Usually happens because of habitat destruction, introduction of exotic species, unregulated illegal hunting, competition, and disease.

WHAT CAN WE DO TO PREVENT ENDANGERMENT?

One thing we can do is stop using pesticides like DDT in foreign countries. The Endangered Species Act protects fish, plants, and other wildlife. We can also create more National Parks and nature reserves.

Most Invasive Species get to a new environment because of humans. Some are get here naturally.

• To help pest control• Released from captivity• Ballast water released from ships• Ornamental Purposes• Used for hunting and fishing game

How They Affect The Environment• displace native species• alter ecosystem processes• reduce native wildlife habitat• reduce forest health and productivity
