1. Seabirds: Ashy and Leach’s storm-petrels are expected to benefit as a consequence of reduced predation and improved survivorship. In particular, eradicating house mice is expected to reduce the numbers of overwintering burrowing owls and resulting owl predation on storm-petrels.
2. Salamanders: The endemic Farallon arboreal salamander is anticipated to benefit from the removal of a likely competitor for invertebrate prey and a potential predator of salamander eggs and juveniles.
3. Invertebrates: Native invertebrates of the South Farallon Islands, including the endemic Farallon camel cricket, are expected to benefit from reduced predation pressure from invasive mice and other predators attracted to the islands by the mice, such as burrowing owls.
4. Plants: Native plants stand to benefit as a consequence of reduced seed and seedling predation.
