Description: At least 4,500 species of foreign origin have established free-living populations in the United States, of which about 15% cause severe economic or environmental harm. Between 1906 and 1991, just 79 species caused an estimated $97 billion in losses. Virtually every economic sector and area of the country is affected, with some of the biggest problems in the east. Usually, exotic species reach the United States with human help, often via international trade. Rates of entry fluctuate, but never drop to zero-creating an even-greater economic and environmental burden. Neither domestic policies nor international agreements have been very successful when it comes to preventing new problems and managing old ones.
