10. Native Species ◦ Species that have evolved in the same area over a long period of time. Introduced Plants ◦ A species that humans have placed in an ecosystem (either intentionally or accidentally) it rarely occurs naturally. Invasive Species ◦ A species whose introduction is likely to cause environmental or human harm because they have no natural enemy.

11.  Personal Travel  Shipments of plants and other materials  Deliberately imported  Some are for aquarium use but find their way into natural landscapes  Disease  Increased competition  Habitat Destruction
