15. What other alternatives were considered and why were they dismissed?

The U.S. Fish and Wildlife Service reviewed all options to remove invasive house mice from the island and prepared an environmental Impact Statement that reviewed scientific literature, input from a broad range of experts, and public input. In total, 49 different removal methods were assessed, including a sustained population control program, the use of bait stations, fertility control, trapping, introduction of a biological control agent such as snakes or cats, and burrowing owl relocation. After reviewing all options in coordination with a variety of federal, state and conservation partners, the U.S. Fish and Wildlife Service conducted several pre-eradication studies, reviewed lessons learned from past projects, and consulted with collaborating agencies. After a thorough assessment grounded in a careful, rigorous and transparent process and science-based decision making, all but two potential action alternatives were dismissed.
