The purpose of this legislation is to amend an existing law to ban the use and possession of body-gripping traps in the National Wildlife Refuge System. The aim is to protect wildlife from inhumane trapping methods and promote more humane wildlife management practices. The key provisions of this law include a complete prohibition on body-gripping traps within the National Wildlife Refuge System, with specific exceptions. Federal agencies can use these traps only for controlling invasive species or protecting threatened or endangered species, but only after exhausting non-lethal methods.
