The North American Racer (Coluber constrictor) is not currently listed under the United States Endangered Species Act at the federal level, which means that the species as a whole does not receive the broad protections afforded to federally listed threatened or endangered wildlife. This absence from the federal list reflects the species' overall abundance and wide distribution across the continent rather than a judgment that all populations are secure. Federal wildlife law in the United States delegates considerable regulatory authority over non-listed native reptiles to individual states, creating a decentralized legal landscape that varies significantly from one jurisdiction to the next.
The Lacey Act, the primary federal statute governing interstate and international wildlife commerce, applies to the North American Racer insofar as it prohibits the transport of wildlife taken in violation of state law across state lines. This means that a racer collected illegally in one state cannot legally be transported to or sold in another state, even if the receiving state has more permissive regulations regarding the species. The Lacey Act's enforcement mechanism thus reinforces state-level protections by extending their effective reach beyond state borders, creating a federal backstop against the laundering of illegally collected specimens through interstate commerce.
In Canada, the North American Racer falls under the jurisdiction of the federal Species at Risk Act (SARA) for certain populations. The Blue Racer subspecies (Coluber constrictor foxii), which in Canada is restricted to Pelee Island in Lake Erie, is listed as endangered under SARA, affording it substantial legal protection including prohibitions on killing, harming, harassing, capturing, or possessing individuals, as well as protections for critical habitat. This federal listing in Canada contrasts with the species' unprotected status at the federal level in the United States and illustrates how national regulatory frameworks can diverge even for the same species occurring in adjacent countries.
The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) does not currently list the North American Racer on any of its appendices, which means that international trade in the species is not subject to CITES permit requirements. This reflects both the species' overall abundance and the limited scale of international commercial trade in North American Racers compared to more heavily traded reptile species. However, any cross-border movement of racers between the United States, Canada, and Mexico remains subject to the wildlife import and export regulations of each country, and individuals transporting snakes across international borders must comply with applicable customs and wildlife inspection requirements.
