The devastating wildfires that recently swept through over 110,000 acres in northwestern North Dakota have been largely contained.
The resulting damage has led to significant soil erosion concerns, according to experts from North Dakota State University Extension. Of course, North Dakota is not the only area that has experienced wildfires, but NDSU’s review of concerns and advice is helpful to anyone in a similar wildfire ravaged area.
The absence of vegetation now poses a severe risk to the landscape's productivity.
The destruction of plant cover and the protective residue layer by the wildfires has increased the susceptibility of the soil to wind erosion.
With this natural barrier gone, the soil is defenseless against the harsh winds prevalent in the region, especially under the current dry conditions.
NDSU experts recommend several proactive measures. Increasing the soil's surface cover is a primary strategy, achievable through the application of manure or other organic residues.
Altering the surface roughness can also effectively reduce wind speed over the soil, providing additional protection.
Maximizing snow retention during the winter months is critical for erosion control, as it covers and shields the soil from direct wind exposure.
Specialists advise against leveling the soil in the aftermath of the fire, as doing so can exacerbate the erosion. Instead, they suggest allowing the accumulated soil to stabilize naturally until the spring, to prevent further degradation.
Implementing these strategies can significantly mitigate the impact of wildfires on soil erosion.
