The Gold Rush brings changes.
The value of Cattle rises dramatically because there is a market for beef. Prior to the arrival of many thousands of Argonauts, cattle were valued for their hides and tallow - the two least perishable goods that could be exported to far-off eastern markets.
The increase in the price of cattle makes land far more valuable than it had been before the Gold Rush.
The Gold Rush also generates a lot of money. Most of it goes to San Francisco-Sacramento region, but some capital drifts southward into Los Angeles.
The Gold Rush has a spillover effect in terms of population. Many argonauts visit Los Angeles on their way to or from the gold fields. Some stay for a short period of time, but other linger or become residents.
In 1850, just a few years after the end of the Mexican-American War, California becomes a state.
Thanks in part to the rapid increase in value of ranchland, and the sometimes informal, or corrupt history of land aquisition during the Mexican era, Californios had difficulty making good on claims to land. American land speculators, or aspiring ranchers were all to happy to contest pre-existing claims on the land in order to stake their own claims.
Americans begin to take over.
Still - many Californios were able to hold on to large ranch estates.
