Placing mulch and vegetation is an effective action to stabilize site soil because it helps to prevent soil erosion and promote moisture retention. Vegetation, such as grass or ground cover plants, establishes roots that bind the soil together, reducing the likelihood of soil displacement caused by wind or water runoff. Mulch further contributes by covering the soil, protecting it from direct rainfall impact and reducing surface temperatures. This combination of mulch and live vegetation creates a sustainable ecosystem that supports soil health and prevents degradation. In contrast, removing all vegetation would leave the soil bare and vulnerable to erosion. Leaving the soil exposed can lead to significant loss due to erosion caused by environmental factors. Using heavy machinery may compress the soil and disturb its structure, further exacerbating erosion and destabilizing the site rather than enhancing soil stability. Proper soil stabilization techniques, therefore, focus on preserving and incorporating vegetation.
