Exposed tree roots: When soil erodes around trees, their roots become increasingly visible above ground. This indicates the soil that once covered these roots has been washed away by water runoff.Prevention method: Install erosion control blankets or mats made of natural fibers (like coir or jute) on sloped areas. These protect the soil surface from rain impact, slow water runoff, and allow vegetation to establish, which further stabilizes the soil with root systems.
