Managing Fire

Fire managers use three tools to mimic fire's natural function in the ecosystem: prescribed fire, mechanical thinning, and wildfire. While visiting Yosemite, you may see evidence of any of these practices.

Prescribed fires are ignited by qualified park fire staff under certain pre-determined conditions. These fires are carefully managed to achieve goals such as public safety (by protecting developed areas) and ecosystem restoration (by clearing unsafe accumulation of dead and down wood).

Mechanical thinning removes smaller trees and brush with tools such as chainsaws. You may see these brush piles while visiting Yosemite. Mechanical thinning helps provide community protection from unwanted wildland fire, and it helps provide safer conditions for firefighters.

Wildfires are caused by lightning and often allowed to burn naturally in certain park wilderness areas under specific conditions, and with close surveillance by park fire staff. These fires are managed in order to fulfill their natural role as an agent of change in the ecosystem. If it is not prudent to allow fires to burn due to nearby infrastructure, weather conditions, or resource availability, park staff will suppress them.

"...we can't cut our way out of the problem. We can't burn our way out. We can't simply suppress. And we can't walk away. But maybe, we can cut a little, burn a little, suppress a little, and sometimes just back off from a fire that we can't hope to stop. The process will take decades, not years, but taken together, a lot of small steps could make a big difference." —Author Stephen J. Pyne
