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

It is important to determine the burn severity of a wildfire as many post-fire assessment and management decisions will be based on this information. Plant mortality, regeneration and reproduction are closely tied to how hot and how long a wildfire burns and will determine the make-up of post-fire plant communities. Burn severity also effects wildlife habitat, changes in the soil, erosion potential and many components of aquatic environments.

Erosion Potential After A Wildfire

 

Assessing the erosion potential after a wildfire is an important step of post-fire management. Erosion is a natural process occurring on landscapes at different rates and scales, depending on geology, topography, vegetation, climate and weather, and is defined as the movement of individual soil particles by wind or water. Erosion is a function of the forces available, the amount of protection to the soil surface, the type of the soil and soil stabilizing components such as roots. It is usually …
