The complete county distribution, spread across 5 California counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

California’s combined state files contain 83 Siskiyou chipmunk records: 83 from iNaturalist and 0 from GBIF. It ranks 151th among 243 mammals in this California record comparison, placing it in the middle 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.

California accounts for about 100% of the mapped GBIF records summarized on the national Siskiyou chipmunk page. That’s a large share of the known record footprint, though differences in survey effort can strongly shape the percentage.
