The world is a giant place for a mouse, particularly a tiny mouse that weighs not more than three pennies. For the aptly named Pacific pocket mouse, the smallest mouse species in North America, the world has offered much more challenges than these going through the common mouse.
Endemic to a slim strip of coastal scrublands, dunes, and riverbanks that when stretched from Los Angeles to the Tijuana River Valley, their numbers began declining sharply within the Thirties, due to human encroachment and habitat degradation. In truth, the Pacific pocket mouse was thought of extinct for a number of a long time. However in 1994, a small inhabitants was rediscovered at Orange County’s Dana Level headlands. It turns on the market have been a number of small populations left, however they have been remoted by distance and artifical obstacles.
Enter the San Diego Zoo Wildlife Alliance, which launched the Pacific pocket mouse conservation breeding and reintroduction program in 2012 to assist save the species from extinction. The primary 12 months of this system noticed the delivery of Pat (named after actor Sir Patrick Stewart), who was born on July 14, 2013.
Now, at 9 years and 209 days previous, Guinness World Information has awarded Pat the title of “Oldest Dwelling Mouse in Human Care.”

Because the San Diego Zoo Wildlife Alliance notes in a press assertion saying the brand new report, the title is “a win for all of the tiny however mighty—and sometimes neglected—species all over the world that play an essential position of their ecosystems.” The Pacific pocket mouse is noteworthy for his or her dispersing of native plant seeds and abetting plant development by means of their digging actions.
Alliance members and companions attended a ceremony by which Debra Shier, Ph.D., Brown Endowed Affiliate Director of Restoration Ecology at San Diego Zoo Wildlife Alliance, accepted a plaque for the accomplishment. Shier created and oversees the Pacific pocket mouse conservation breeding program.
“This recognition is so particular for our crew, and is critical for the species,” stated Shier. “It’s indicative of the dedication and unimaginable care we as a corporation present for every species, from the biggest to the very smallest. This acknowledgment can also be a logo of appreciation for species that individuals don’t know a lot about as a result of they’re not charismatic megafauna, however are simply as important for ecosystem operate. These neglected species can usually be present in our personal backyards—just like the Pacific pocket mouse.”
As for the Pacific pocket mouse (and its advocates), it is not all simply awards and glam. These children are busy. In 2022, in response to the Alliance, the crew recorded the earliest breeding occasion and pup delivery within the historical past of this system, to not point out a report of 31 litters, for a complete of 117 pups through the spring and summer season months.

Many of those mice shall be reintroduced into native habitats this spring.
Whereas there may be a lot debate about zoos, the pocket mouse program is an efficient instance of how some zoos have pivoted from leisure to conservation. Along with the Alliance’s breeding program, the researchers research habits, ecology, genetics, microbiome, and physiology to “finest help genetically numerous, wholesome and behaviorally competent mice which are properly ready for reintroduction into native habitats.”
Partnering with Orange County Parks, the U.S. Fish and Wildlife Service, and the California Division of Fish and Wildlife, in 2016 the Alliance started to determine a brand new inhabitants of Pacific pocket mice in Orange County’s Laguna Coast Wilderness Park.
As of 2017, the mice have been breeding with out human intervention. Not unhealthy for a tiny mouse that was as soon as thought gone endlessly … and who can now discover its identify within the Guinness Guide of World Information.
