Abstract     
Unregulated commercial harvest remains a major threat for turtles across the globe. Due to continuing demand from Asian markets, a significant number of turtles are exported from the United States of America (US). Beginning in 2007, several southeastern states in the US implemented restrictions on the commercial harvest of turtles, in order to address the unsustainable take. We have summarized freshwater turtle exports from the US between 2002 and 2012 and demonstrated that the magnitude of turtle exports from the US remained high although the exports decreased throughout the decade. Louisiana and California were the major exporters. The majority of exports were captive bred, and from two genera, Pseudemys and Trachemys. We review the changes over the decade and speculate that the increase in export of wild turtles out of Louisiana after 2007 could be a consequence of strict regulations in surrounding states (e.g., Alabama, Florida). We suggest that if wild turtle protection is a goal for conservation efforts, then these states should work together to develop comprehensive regulation reforms pertaining to the harvest of wild turtles. The following genera were exported: Apalone, Chelydra, Chrysemys, Clemmys, Deirochelys, Emydoidea, Graptemys, Kinosternon, Macroclemys, Malaclemys, Pseudemys, Sternotherus, Terrapene, and Trachemys. Combined, Pseudemys and Trachemys represented between 61% (Florida; 1,321,202 individual turtles) and 96% (Louisiana; 81,404,579 individual turtles) of all species traded from the top four exporting states (Fig. 2). Chelydra consisted of 12% (4,248,913 individuals) of the exports from California, 5% (99,846 individuals) of the exports from Texas, and 5% (125,276 individuals) of the exports from Florida. Apalone consisted of 25% (540,815 individuals) of all exports from Florida and 5% (99,024 individuals) from Texas. For the top four exported genera (Apalone, Chelydra, Pseudemys, and Trachemys), regression coefficients showed significant increase in traded Trachemys in Louisiana (p = 0.02) and significant decrease in traded Trachemys in California (p<0.01). Traded Apalone significantly increased in Florida and California (p<0.01) while traded Chelydra increased in Louisiana and California (p<0.01).
