Point Blue is supportive of eradicating the mice from the Farallon Islands based on extensive scientific evaluations.  We support the potential use of rodenticides as permitted for conservation use and explored through an Environmental Impact Statement (EIS).

Point Blue, in partnership with the USFWS, has been studying Farallon wildlife since 1967. During this time, we have documented the effects of the non-native house mouse to the island ecosystem.  From our over 45 years of research, we feel there is a need to restore the island by eradicating the non-native house mouse.  We have developed three research summaries that present the impact of the invasive house mice to the island ecosystem, and illustrate the need to remove them.

Population Viability of Western Gulls. Report to the US Fish and Wildlife Service.

Non-lethal hazing can protect gulls from exposure to rodenticide. Report to the Oiled Wildlife Care Network.

Reducing burrowing owl predation to benefit Farallon ashy storm-petrels. Report to US Fish and Wildlife Service.

Environmental Impact Statement

To investigate how to remove the mice from the Farallones, Point Blue has contributed our data and research findings to the USFWS Environmental Impact Statement, which has outlined three alternatives for mouse removal.  The three alternatives include two options involving a rodenticide, and a third option of no action.  USFWS is now considering the best approach.

Farallon National Wildlife Refuge Ecosystem

The islands of the Farallon National Wildlife Refuge host the largest seabird breeding colony in the United States outside of Alaska and Hawai`i. Twenty-five percent of California’s breeding seabirds, with more than 300,000 individuals of 13 species, can be found there. About fifty percent of the world’s population of the rare Ashy Storm-Petrels (listed as a Species of Management Concern by the U.S. Fish and Wildlife Service and Endangered by the International Union for Conservation of Nature) breed on the Farallon National Wildlife Refuge islands. Unfortunately, the presence of introduced, non-native house mice threatens this globally significant seabird colony.

Point Blue on the Farallones

Point Blue scientists have worked on the Farallones 24 hours a day, 7 days a week and 365 days a year since 1968 in partnership with the USFWS stewarding, monitoring and protecting seabirds, marine mammals and other wildlife. During these 44 years, Point Blue has documented numerous direct and indirect impacts of mice on the Farallon ecosystem and it’s wildlife. We will continue to provide scientific expertise in the eradication planning process and will continue monitoring and stewarding Farallon wildlife.
