Invasive Species

Plants, animals, fungus, etc. from other parts of the world that are brought here can wreak havoc on our ecosystem. Without the natural predators that would keep them in check in their native environment, some non-natives become invasive when their populations spiral out of control. Examples include zebra mussels that were accidentally introduced from Russia that have clogged water intake valves and purple loosestrife, a plant that invades and takes over wetlands.
