The Ahwahnechee people, who inhabited Yosemite for thousands of years, utilized controlled, low-intensity fires to maintain open meadows and promote the growth of vital resources like black oaks. These practices prevented larger, more destructive wildfires that have become a problem in recent years after park policies shifted to fire suppression.
“The Ahwahnechee served as ancient environmental engineers of the Yosemite Valley. By setting frequent low-intensity fires, they kept the valleys open meadows from being choked out by dense conifer forests.”
“These controlled burns cleared underbrush, recycled nutrients into the soil, and stimulated the growth of black oaks, a vital resource as acorns were a staple of their diet and of the animals they hunted.”
“The consistent small-scale fires of the Ahwahnechee actively prevented the larger, more disastrous wildfires that the park has experienced in recent years.”
