The Brown Water Snake (Nerodia taxispilota) does not currently carry any federal listing under the United States Endangered Species Act. The species is not classified as threatened or endangered at the national level, reflecting its relatively stable population status across much of its southeastern range. This absence of federal listing means that the Brown Water Snake is not subject to the comprehensive protections that apply to species on the federal endangered species list, including prohibitions on take, habitat destruction, and interstate commerce.
Despite the lack of an Endangered Species Act listing, the Brown Water Snake does fall under the jurisdiction of several broader federal statutes that regulate wildlife handling and commerce. The Lacey Act, originally enacted in 1900 and subsequently amended, prohibits the interstate transport of wildlife taken in violation of state law, meaning that a Brown Water Snake collected illegally under a particular state's regulations cannot be legally transported across state lines regardless of the destination state's own rules. This federal backstop ensures that state-level protections for the species cannot be circumvented simply by moving animals to jurisdictions with more permissive regulations.
The Brown Water Snake is also not listed under the Convention on International Trade in Endangered Species of Wild Fauna and Flora, the international treaty that regulates cross-border trade in wildlife species of conservation concern. This is consistent with the species' limited geographic range within the southeastern United States and its absence from international commercial trade in any significant volume. However, any international shipment of the species would still be subject to the general wildlife import and export regulations administered by the United States Fish and Wildlife Service.
It is important to note that the absence of federal threatened or endangered status does not mean the Brown Water Snake is without legal protections. The species benefits from a complex web of state-level wildlife regulations that vary considerably across its range, and these state laws often provide the most practically relevant legal framework governing how people may interact with the species. Prospective keepers, collectors, and researchers should never assume that the lack of a federal listing translates to unregulated access to the species.
