Reducing post-fire hillslope erosion with wood shreds

Documents and Media Posted on: January 23, 2015
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.

Production and aerial application of wood shreds as a post-fire hillslope erosion mitigation treatment

Publications Posted on: August 02, 2013
Guidelines for the production and aerial application of wood shred mulch as a post-fire hillslope treatment were developed from laboratory and field studies, several field operations, and the evaluations of professionals involved in those operations. At two early trial sites, the wood shred mulch was produced off-site and transported to the area of use.

Using QuickBird imagery to detect cover and spread of post-fire straw mulch after the 2006 Tripod Fire, Washington, USA

Publications Posted on: April 25, 2011
Agricultural straw mulch is a commonly applied treatment for protecting resources at risk from runoff and erosion events after wildfires. High-resolution QuickBird satellite imagery was acquired after straw mulch was applied on the 2006 Tripod Fire in Washington. We tested whether the imagery was suitable for remotely assessing the areal coverage of the straw mulch treatment.

Measuring effectiveness of three postfire hillslope erosion barrier treatments, western Montana, USA

Publications Posted on: April 30, 2009
After the Valley Complex Fire burned 86 000 ha in western Montana in 2000, two studies were conducted to determine the effectiveness of contour-felled log, straw wattle, and hand-dug contour trench erosion barriers in mitigating postfire runoff and erosion. Sixteen plots were located across a steep, severely burned slope, with a single barrier installed in 12 plots (four per treatment) and four plots left untreated as controls.

Protection from erosion following wildfire

Publications Posted on: October 02, 2006
Erosion in the first year after a wildfire can be up to three orders of magnitude greater than the erosion from undisturbed forests. To mitigate potential postfire erosion, various erosion control treatments are applied on highly erodible areas with downstream resources in need of protection.
