The complete county distribution, spread across 20 California counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Big-eared Woodrat records in California fit chaparral, oak woodland, and rocky slopes.

Reports center on the Coast Ranges and Sierra Nevada foothills rather than California’s open deserts. They show where people have documented the species, and they don’t rank California’s best habitat.

Reports rise most clearly in Apr–May, Dec. That pattern can reflect animal movements, weather, and observer effort, so it isn’t a population count.
