California’s brown bear file holds 33 records, and every one of them documents an animal that’s no longer here. The species disappeared from the state generations ago, so what these records show is history, not a place to go looking for one today.

The animal on the state flag, gone from the land

Brown bears once ranged across California’s Central Valley grasslands and the oak-and-chaparral foothills of the Coast Ranges, feeding on acorns, salmon runs, and the seasonal bulbs and grasses of the valley floor. That same bear sits on the state flag and seal today, a design adopted while grizzlies still roamed the hills behind it. Trapping and shooting through the 19th and early 20th centuries erased the bear from California well before the rest of its range in the Lower 48 came under federal protection in 1975.

Records scattered across the calendar, none of them recent

California’s 33 records show no real seasonal pattern the way an active resident species would, because they trace old specimens and historical accounts rather than ongoing sightings. That flat, scattered spread across the months is itself a signal: nothing is being observed here now, only documented from the past.

Status in California

NatureServe ranks the brown bear SX, presumed extirpated, in California, the clearest possible confirmation that the state’s grizzlies are gone. It’s still classified as native, a status that reflects the bear’s genuine historical range rather than any bear alive in California’s mountains today.
