For thousands of years the Esselen, Salinan, and Ohlone burned these mountains every five to fifteen years, until a 1793 Spanish ban and the mission system broke the practice. One Esselen family kept burning into the 1970s, until the Forest Service ordered them to stop, and their elders predicted catastrophic fires. Recent land returns to the tribe close the story.
How widespread Indigenous burning was is argued. Ethnoecologists see systematic landscape management; some chaparral ecologists say it clustered near villages and travel routes, with lightning driving fire in remote terrain.
