  • Air Quality. The smoke and particulates released during controlled burns can negatively affect air quality. …
  • Water Quality.

How do prescribed burns prevent wildfires?

Prescribed fire decreases the intensity of a subse- quent wildfire primarily by reducing fuel loads, especially of the finer elements in the more aerated fuel layers that gov- ern fire spread (Rothermel 1972), but also by disrupting the horizontal and vertical continuity of the fuel complex.

Why are people against prescribed fires?

There has been a growing chorus of political leaders and often firefighting agency personnel who suggest that greater use of prescribed fire could preclude the establishment of large blazes or at least slow advances. Advocates also assert it could reduce overall smoke and improve forest health.
