What is a common reason for using ground cover in landscape design?

Using ground cover in landscape design is often done to prevent soil erosion. Ground cover plants typically have an extensive root system that helps stabilize the soil. This is particularly useful on slopes or in areas where water runoff is a concern, as the roots help anchor the soil and reduce the likelihood of it washing away during heavy rains or storms. Additionally, ground cover can protect the soil surface from the impact of raindrops, further minimizing erosion.

While enhancing lighting, maintaining temperature, and facilitating pollination may have their place in landscape design, they do not directly relate to the primary function of ground cover. Ground covers are primarily utilized for their ability to cover and protect the soil, making them a vital element in erosion control strategies.
