Early historians of California wrote about the smoky smell in the air through summer. Native Americans relied on fire for things like herding animals for a big hunt and creating open space for villages. Cowboys used fire to sustain pastures for grazing. “When the cowboys left higher elevations, they would light behind them as they left — light the mountains or hills on fire,” says Jennifer Hinck- ley, a fire management specialist formerly with the U.S. For- est Service and now with the U.S. Fish and Wildlife Service. Upon returning in the spring, there’d be new grass for cows and sheep to forage. As miners arrived for the gold rush, trees were cut down to make way for the Trans- continental Railroad and to supply lumber for industry and settlements. Americans believed the country’s natural resources were infinite. “There was so much of it, there’s nothing we could do to put a dent in it, even though we were denting big-time,” Hinckley says. “We were cutting down everything we could cut down.” Meanwhile, as cities grew overcrowded and polluted in the late 1880s, affluent Americans retreated outdoors for fishing, camping, hiking and bird-watching. Preservationists suggest- ed nature had inherent value, and conservationists argued nature must be conserved for its economic benefit to people. 64 comstocksmag.com | June 2019 In the early 1900s, President Theodore Roosevelt established 230 million acres of national parks, forests and monuments and oversaw the creation of the Forest Service in 1905. Then in 1910, forest fires broke out in Montana and tore through the Northern Rocky Mountains in what came to be known as the Great Fire. “The Forest Service actually man- aged to save a bunch of towns and people, and it became very clear that in terms of establishing a mission … that fire was going to be one of the things that was going to keep the Forest Service financially alive with politicians in [Washing- ton, D.C.],” North says. “It became a real central focus for the agency itself and has remained so.” By the 1920s, a shift to fire suppression had taken hold. While some scientists at the time argued that the right kind of fire benefitted forest ecosystems, their voices were overshad- owed, North says. Outdoor recreationists didn’t much care for wildfire, and it posed a danger to towns and the emerg- ing commercial timber industry. “A lot of people were saying, ‘Hmm, we could be growing a lot of board feet and more fiber if we got rid of fire,’ ” North says. “That was definitely one of the reasons fire was put out.” Over the ensuing decades, wildfires continued to be squashed. In the 1960s, Americans grap- pled with the effects of water and air pollution, which led Congress to pass legislation that fur- ther restricted the use of fire as a tool. By the 1990s, what had become a flourishing timber industry was about to enter a period of conflict and consolidation that would set up some of the conditions — and challenges — California faces today in effectively managing its forests. — Sena Christian
