California’s combined state files contain 19 “Southern Pacific Jumping Mouse” records: 19 from iNaturalist and 0 from GBIF. It ranks 197th among 243 mammals in this California record comparison, placing it in the lower third. That’s a ranking of submitted records, not a head count of animals.
The California files don’t contain a complete month-by-month series for this species. That gap limits any claim about seasonal timing, and it doesn’t show that the animal leaves California during part of the year.
The national summary doesn’t provide a California share that can be compared cleanly with this state total. It’s better to treat these records as evidence of documentation effort rather than a measure of the species’ wider range.
