Mid-elevation Sierra conifer forests are naturally open. When fires are artifically suppressed, forests become dense, with smaller crowded trees and unnatural amounts of deadwood that lead to catastrophic wildfire.

Why Does the National Park Service Use Fire?

Fire has been a natural part of the Sierran ecosystem for centuries. Natural fires swept through these plant communities at intervals that provided conditions for many plant species to regenerate. Fire thins competing species, recycles nutrients into the soil, releases and scarifies seeds, and opens holes in the forest canopy for sunlight to enter. All of these are critical to forest health and natural cycles of growth and decomposition.

Plants are not the only living things that have evolved with and adapted to fire. Animal species are just as much a part of the "fire environment." With the increased forage that results after a fire, many animals low on the food chain experience increases in their populations; therefore species above them on the food chain also benefit.

Despite the evidence that fire is a necessary element in the Sierra Nevada, over most of the past century people have feared and suppressed it whenever possible. Especially in the western United States, the accumulation of dead forest litter and duff during that time now presents extreme hazards to the health of the trees, soil, and wildlife, to humans living in these areas, and to the taxpayer who has to fund the fighting of catastrophic wildfires.

Prescribed fire is used in Sequoia and Kings Canyon National Parks to restore this natural process to the forests. These fires are strategically used to reduce the risks that unnaturally heavy fuels pose to humans and ecosystems.

Did You Know?

Sharp, rocky crest of the Sierra Nevada.

The Sierra Nevada is still growing today. The mountains gain height during earthquakes on the east side of the range. But the mountains are being shortened by erosion almost as quickly as they grow. This erosion has deposited sediments thousands of feet thick on the floor of the San Joaquin Valley.
