Brown Bear in California, by the numbers

Presumed Extirpated in California 228th most recorded of 233 mammals logged in California

Records from 2000–2026.

Seasonality

No dated California records from 2000 to 2026.

California has no brown bear records from 2000 to 2026, and that’s no gap in the file. The species disappeared from the state generations ago, so its story here 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.

Nothing recorded since 2000

With no records in the 2000 to 2026 window, there’s no seasonal pattern to read. What remains of California’s grizzlies is old museum specimens and historical accounts, the trace of an animal that’s gone rather than one anyone observes now.

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.
