Abstract

The ability of mulch treatments to reduce sediment yields from natural rainfall and resulting overland flow was measured using hillslope plots on areas burned at high severity following 4 wildfires in the western United States : Hayman in Colorado (2002); Hot Creek and Myrtle Creek in Idaho (2003); and School in Washington (2005). Wheat straw mulch, wood strand mulch, and hydromulch were evaluated along with untreated control plots on multiple fires for 4 to 7 years after burning. It is shown that sediment yields were related to rain intensity, time since fire, and ground cover. Wood strand mulch reduced sediment yields for up to 4 post-fire years. Straw mulch reduced first post-fire year sediment yields at 2 of 4 fires. Hydromulch did not reduce post-fire sediment yields in any years
