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 92 Rock Squirrel records: 27 from iNaturalist and 65 from GBIF. It ranks 184th 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 monthly series reaches its high point in May, with 8 records in the busiest month. Records appear in 6 of 12 months, so the pattern shows when sightings were documented, not when the species must be present or absent.

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.
