What is meant by 'soil bioengineering' in erosion control?

Soil bioengineering refers to the practice of utilizing living plants and natural materials to enhance soil stability and prevent erosion. This approach leverages the natural growth patterns of plants, whose root systems help bind the soil together, thereby reducing the risk of soil loss due to wind or water erosion. By integrating vegetation with natural materials such as logs, woven branches, and other biodegradable elements, soil bioengineering creates a more sustainable and environmentally friendly solution to erosion control.

This not only helps to stabilize the soil but also promotes biodiversity and enhances the ecological function of the area. It contrasts with methods that rely exclusively on synthetic or mechanical solutions, as well as structures made solely from man-made materials, which may not provide the same long-term benefits to the environment.
