Federal legal authorities: guidance for application to the early detection of and rapid response to invasive species

Federal agency programs and associated actions are contingent on having the legal authority to act. There is no single authority established to direct the early detection of and rapid response to invasive species (EDRR). Rather, a patchwork of authorities unevenly addresses various aspects of the suite of EDRR measures. To support the development of national EDRR capacity, it is essential to delineate the federal legal statutes, regulations, and policies that enable or limit invasive species EDRR. Here we set forth general principles and a checklist of actions that agencies can refer to when they construct a more comprehensive EDRR legal and policy framework for addressing invasive species. This guidance is intended to complement the review and analysis of federal authorities contained elsewhere in this issue (Burgos-Rodriguez and Burgiel in Biol Invasions. 10.1007/s10530-019-02148-w, 2019, this issue).
