11. How is the Service proposing to remove invasive mice from the South Farallon Islands?

The Service conducted a thorough, science based Environmental Impact assessment over a number of years and came up with three alternatives to consider:

  1. Alternative A: Taking No Action, which would allow mice to remain on the South Farallon Islands and continue to negatively impact the islands’ storm-petrels and other native and endemic species.
  2. Alternative B (the Service’s Preferred Alternative): Eradicate invasive house mice from the South Farallon Islands by the aerial broadcast of rodent bait containing Brodifacoum-25D Conservation.
  3. Alternative C: Eradicate invasive house mice from the South Farallon Islands by the aerial broadcast of rodent bait containing Diphacinone-50 Conservation.
