Description

Wood shreds and other mulch treatments (agricultural straw, woods strands, and hydromulch) are frequently recommended as a technique used to stabilize hillslopes by providing immediate ground cover and to mitigate post-fire increases in runoff and erosion rates.

Key Points:

  • Post-fire mulch treatments provide ground cover on hillslopes where erosion mitigation is needed.
  • Laboratory and field studies have shown that wood shred mulch can be an effective post-fire hillslope treatment.
  • Wood shreds have been successfully produced from burned and green trees.
  • The effectiveness of postfire mulch applications should be monitored and assessed to determine uniformity of ground cover spread and the percent ground cover achieved.
