Vegetation response after post-fire mulching and native grass seeding

Publications Posted on: July 08, 2015
Post-fire mulch and seeding treatments, often applied on steep, severely burned slopes immediately after large wildfires, are meant to reduce the potential of erosion and establishment of invasive plants, especially non-native plants, that could threaten values at risk. However, the effects of these treatments on native vegetation response post fire are little studied, especially beyond one to two years.

Reducing post-fire hillslope erosion

Documents and Media Posted on: January 23, 2015
Post-fire erosion can be a major issue when trying to protect downstream values at risk. Mulch treatments (agricultural straw, woods strands, wood shreds, and hydromulch) are frequently recommended as a technique used to mitigate post-fire increases in runoff and erosion rates. However, the comparative effectiveness of the various mulch treatments is not well established. Key Points:Document Type: Briefing Papers

Reducing post-fire runoff and sediment yields

Documents and Media Posted on: January 23, 2015
Agricultural straw, hydromulch (a matrix of organic fibers mixed with water that binds to soil), and wood shred or wood strand mulches increasingly are being used as postfire hillslope treatments. However, the differences in effectiveness in reducing measured runoff, sediment yields, and peak flow rates among these mulch treatments are not fully understood.

Post-fire mulching for runoff and erosion mitigation; Part I: Effectiveness at reducing hillslope erosion rates

Publications Posted on: April 29, 2013
Mulch treatments often are used to mitigate post-fire increases in runoff and erosion rates but the comparative effectiveness of various mulches is not well established. 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 four wildfires in the western United States.

Post-fire mulching for runoff and erosion mitigation; Part II: Effectiveness in reducing runoff and sediment yields from small catchments

Publications Posted on: April 29, 2013
Agricultural straw, hydromulch, and wood shred or wood strand mulches increasingly are being used as post-fire hillslope treatments, but the differences in effectiveness among these mulch treatments are not fully understood.

The effectiveness of aerial hydromulch as an erosion control treatment in burned chaparral watersheds

Publications Posted on: September 21, 2011
High severity wildfire can make watersheds susceptible to accelerated erosion, which impedes resource recovery and threatens life, property, and infrastructure in downstream human communities. Land managers often use mitigation measures on the burned hillside slopes to reduce postfire sediment fluxes. Hydromulch, a slurry of paper or wood fiber that dries to a permeable crust, is a relatively new erosion control treatment.

Post-fire treatment effectiveness for hillslope stabilization

Publications Posted on: August 03, 2010
This synthesis of post-fire treatment effectiveness reviews the past decade of research, monitoring, and product development related to post-fire hillslope emergency stabilization treatments, including erosion barriers, mulching, chemical soil treatments, and combinations of these treatments.
