Law Enforcement

The Service’s wildlife inspection program forms the Nation’s frontline defense at ports of entry by interdicting injurious species. Wildlife inspectors are stationed at 38 major U.S. airports, ocean ports, and border crossings, where they monitor imports and exports to ensure compliance with U.S. laws and regulations. Wildlife inspectors focus on detecting and deterring illegal trade in protected species and preventing the introduction of injurious wildlife.

As part of Service efforts to prevent such introductions of injurious wildlife, Service special agents investigate illegal interstate commerce of injurious species (including internet sales) and assist State counterparts with the enforcement of both Federal injurious species prohibitions and State laws that ban the introduction, possession, and sale of State-listed injurious species.
