Mammalian Predators

Introduced rodents (several species of rats and mice), the small Indian mongoose (Herpestes auropunctatus), and feral cats (Felis catus) have had devastating impacts on oceanic islands worldwide. The continued presence of these species in the Hawaiian Islands has profound impacts to native plant and animal communities and is a serious impediment to native species recovery efforts.

  • Long-term, landscape-scale rodent management has been historically used in agricultural situations and is being accomplished to a limited extent for conservation purposes. In addition, successful introduced rodent eradication efforts on islands have a fairly extensive history. The Pacific Islands Fish and Wildlife Office Invasive Species Program provides partner agencies and other stakeholders with technical assistance in implementing control strategies targeting introduced rodents for the protection and conservation of native species. A successful integrated control program requires strong support and continued cooperation among Hawaii conservation land stewards, industry, and the public.
