Which statement best describes the purpose of erosion control blankets on slopes?

• A. Long-term stabilization for decades.
• B. Use on level ground only.
• C. Provide temporary stabilization, reduce erosion on slopes, and support vegetation establishment in challenging conditions.
• D. They are not used on slopes.

Answer: (C)

Erosion control blankets on slopes are meant to provide short-term stabilization while vegetation becomes established. They protect soil from the impact of raindrops, slow surface runoff, and help seeds and seedlings germinate by retaining soil moisture—especially where slopes are steep or soils are bare and conditions are challenging. Because this protective role is temporary, they’re not designed for decades of stabilization; once plants are established, the blankets can be left in place or biodegrade as needed. They’re specifically used on slopes, not just on level ground. This combination—temporary stabilization, erosion reduction on slopes, and support for vegetation establishment in difficult conditions—is what the statement describes.
