The complete county distribution, spread across 6 California counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

The Fresno kangaroo rat belongs to the San Joaquin Valley floor and its dry western foothills, and its 43 California records stay inside that one region. Kern County holds 29 of them, San Luis Obispo County 6, and Kings, Tulare, Fresno, and San Benito counties only a handful between them.

Most of that valley floor is now farmland, roads, and towns, so the alkali scrub and sandy grassland this kangaroo rat depends on survive as scattered fragments. A nocturnal rodent this size seldom shows up in casual sightings, and blank stretches likely say more about where nobody traps at night than about where the animal is missing.

April is the busiest month with 15 records, and August adds a smaller second rise. With so few records in total, that timing more likely reflects when survey crews were working than any real shift in the animal’s activity. iNaturalist accounts for 22 of the records and GBIF for 34, with some entries shared between the two.
