San Diego pocket mouse reports come from southern California’s dry coastal scrub, rocky slopes, and desert edges. The Salton Sea region captures the inland part of that story, whereas the Klamath Basin and San Francisco Bay lie far outside the most useful geographic frame for this animal.
September and October stand well above the other months, with April and July forming smaller rises. Reports nevertheless span the calendar. Because this mouse is nocturnal and often found through targeted trapping, changes in survey dates can outweigh changes in visibility to casual observers.
