This chapter explores patterns of vertebrate importation into the United States over time by summarizing the magnitude of individuals and species imported, geographic origins, and the relationship of this trade to biological invasions. During 1970-2010, the United States imported approximately 4000 species and more than 125 million individuals of amphibians, reptiles, birds, and mammals. For many taxonomic groups, the number of species and individuals imported is increasing over time, and consequently the number of species introductions for these groups is also increasing. Forty years ago, Africa and Central and South America contributed the majority of species imported and released in the wild in the continental United States. Today, Asia is emerging as important trading partner and may contribute to introductions in the future. As part of the push for a global dissemination of invasive species information, trade data from the United States, as well as other countries, should be incorporated and maintained within a global information network to secure its availability for future research. Data on the global trade in live vertebrates can contribute to the development of an international regulatory framework for invasive species prevention.
