    Management Notes for this Location:
    Bait stations were used to control numbers of Rattus rattus in California's Central Valley in October-December 2003. The strategy proved effective in reducing rat numbers and their predation on nesting songbirds. The labour involved and the inaccessibility of the densely vegetated areas of riparian forests may limit the implementation of this strategy on a larger scale.
