Wisconsin Mound Soil Absorption System and Area FillPractice Exam

How should shrubs and trees be handled during site preparation?

1. Cut at ground level with stumps left in the ground

2. Completely uprooted

3. Trimmed to the ground

4. Left untouched

The correct answer is: Cut at ground level with stumps left in the ground

The appropriate method for handling shrubs and trees during site preparation involves cutting them at ground level while leaving the stumps in place. This approach is beneficial for several reasons. Firstly, leaving the stumps intact minimizes soil disturbance, which helps preserve the existing soil structure and microbial activity critical for future plant growth. Additionally, stumps can contribute to soil stabilization and reduce erosion. This method also promotes a natural decomposition process, wherein the organic material will eventually enrich the soil as it breaks down. Furthermore, this technique is less labor-intensive and may require fewer resources compared to completely uprooting the plants, which could entail heavy equipment and significant soil disruption. In contrast, completely uprooting would expose more soil and disrupt the ecosystem significantly. Trimming to the ground might not adequately address the root system and could lead to regrowth issues. Leaving the vegetation untouched would not prepare the site adequately for construction or other land use, which is why the chosen method of cutting shrubs and trees at the ground level is the most effective approach.
