Most of the Californian land in question is owned and managed by the federal government. See eg. this map of land ownership in CA - green, orange, and pink are various federal agencies, while brown is CA state/county lands and yellow is private:

Land management in the west is different from the east. On the east coast almost everything is private, then divided up into municipal, county, and state governments. In the West large chunks of land are still owned by the federal government. Private ownership under state authority is only about 40% in CA and less than 20% in NV.
