The Pacific pocket mouse, once thought to be extinct, has seen a significant increase in population thanks to conservation efforts. Since 2006, over 530 mice have been reintroduced to their native habitats in Southern California, with a third population established in North San Mateo. Genetic rescue efforts have also been implemented to maintain the species' genetic diversity.
