Some are aquatic critters that hitchhiked in the cargo holds of ships. Others were plants intentionally introduced by people who craved prettier gardens. However they entered the country, invasive plants, animals, and microbes cost the United States an estimated $100 billion annually. This federal Web site corrals information on invasive species monitoring, prevention, and control from governments and other sources. Visitors can read about a particular state's efforts, such as laws on animal and plant importation and “hit lists” of troublesome alien species. Resource managers can use the site's tool kit to locate experts and find out how to stamp out and thwart invasions. The site also profiles about 50 of the nastiest interlopers, such as the brown tree snake, which has wiped out 10 of Guam's 13 native bird species since World War II.
