Using mulch to control erosion after a wildfire is a very common practice. Research has shown that mulching is the only treatment which consistently and significantly reduced erosion rates after a burn by immediately increasing the percent of ground cover, compared to gradually increasing cover by growing vegetation such as grass.

Mulch is used to cover the soil, thereby reducing rain impact, overland flow, soil erosion and the rapid …

Using barriers to control erosion after a wildfire is a common practice. Barriers are installed on hillslopes and in streams to slow water flow, increase infiltration, and trap sediment. There are several types of barriers:

  • Log barriers are anchored on the contour of burned slopes to provide immediate protection. They are often used where erosion rates will be high. This treatment is appropriate for slopes of less than 40

Erosion Control after a Wildfire

Erosion is probably one of the most common concerns after a wildfire. Post-fire erosion depends on many factors, but generally erosion hazard increases as slope increases and vegetative cover decreases. To be safe, assume all drainages in steep hilly areas can carry debris flows and that they are vulnerable after a wildfire.

Erosion

Erosion is a natural process. The amount of erosion after a burn depends on storm events, burn severity, slope, soil type, and the condition of the post-fire …
