The California grizzly (Ursus arctos californicus) is an extinct subspecies of the grizzly, the very large North American brown bear. "Grizzly" refers to the golden and grey tips of its hair. Genetically, North American grizzlies are closely related; in size and coloring, the California grizzly was much like the grizzly of the southern coast of Alaska. In California, it was particularly admired for its beauty, size, and strength. Many accounts from pioneers describe grizzlies in long, bloody fights with angry longhorn bulls, and often winning. Early on, the grizzly became a symbol of the State, was the basis of the state flag, and historically, California was known as the "Bear State."
In 1866, a grizzly weighing 2,200 pounds (1,000 kg) was killed in Valley Center, California, the biggest bear ever found in California,[1] unsurpassed until John Lang shot the world's biggest bear — 2,320 pounds (1,050 kg) — near his ranch by Canyon Country, in 1873.[2]
California still has habitat for about 500 grizzlies,[3] and if the North Cascade population recovers and expands, eventually the grizzly will likely return to California. There are however only about 20 of these bears remaining in that ecosystem.[4]
Historically, all North American grizzlies were grouped together as one unique species until DNA testing revealed that they should properly be grouped taxonomically in the same species as the smaller, European brown bears. Thereafter, Californian grizzlies were re-classified in their own subspecies alongside the brown bear. Properly, all subspecies in North America are known as Grizzlies and until recently, the California Grizzly was classified Ursus horribilis.
Originally, the California territory was known as the "Bear State" owing to extensive numbers of the world's largest bears, the blond and powerful California grizzlies, ranging throughout. Later, the nickname "Golden State" was added noting the region's 1848 gold rush discovery and its native golden poppy flora.[5]
The California grizzly is one of the state’s most visible and enduring symbols, adorning both the state flag and seal. The Bear Flag first flew in 1846 as a symbol of the short-lived California Republic, but was replaced by a second version adopted by the State Legislature in 1911.[6] The bear symbol became a permanent part of the State Seal in 1849. The California Grizzly was designated the official State Animal in 1953.[7][8] The bear is celebrated in name and as mascot of the sports teams of the University of California, Berkeley (the California Golden Bears), and of the University of California, Los Angeles (the UCLA Bruins) and in the mascot of University of California, Riverside (Scottie the Bear, dressed in a Highland kilt). The California Maritime Academy operates a training ship named "Golden Bear".
As European settlers began to populate California, the grizzly killed livestock and interfered with the rancheros. Mexican caballeros roped grizzlies, dragging them into doomed public battles with wild bulls.[citation needed] This popular spectator sport inspired betting as to whether the bear or the bull would win. One account is that Horace Greeley, after seeing such a fight, gave the modern stock market its "bear" and "bull" nicknames — based on the fighting styles of the two animals: the bear swipes downward while the bull hooks upward. Less than 75 years after the discovery of gold, every grizzly bear in California had been tracked down and killed. The last hunted California grizzly was shot in Tulare County, California in August 1922. Later, in 1924, a grizzly known to roam an area of the southern Sierras was spotted for the last time, and thereafter, grizzlies were never seen again in California.[1][9]
