Controlled burns help maintain the Sierra Nevada ecosystem by reducing excess vegetation and preventing larger, more destructive wildfires.

Controlled burns (or prescribed fires) are a crucial practice for managing and maintaining the health of the Sierra Nevada's ecosystem. By intentionally setting small, controlled fires, forest managers reduce the build-up of dead vegetation, which can serve as fuel for larger wildfires. These controlled burns help to restore natural fire cycles, improve habitat for wildlife, and increase the health of certain plant species. Without this practice, the ecosystem becomes more vulnerable to catastrophic wildfires and ecosystem imbalances. It is a sustainable and effective approach for preserving the region's biodiversity and resilience.
