What is the term for the wearing away of trails?

The term "footpath erosion" accurately describes the process of the wearing away of trails, particularly those that are frequently used by pedestrians or hikers. It refers to the gradual removal of soil and vegetation along established pathways, which is often exacerbated by factors such as foot traffic, weather conditions, and the physical characteristics of the terrain.

This term is used specifically in the context of geography and environmental science to refer to the environmental impact of human activity on trails, leading to issues such as soil compaction, loss of biodiversity, and increased runoff. Understanding footpath erosion is crucial for developing sustainable management practices for outdoor recreational areas, ensuring they remain accessible while minimizing ecological damage.

Other terms, such as trail development, pathway damage, and surface degradation, might relate to broader concepts of trail maintenance or environmental deterioration, but they do not specifically pinpoint the phenomenon of soil and vegetation removal due to pedestrian use, making "footpath erosion" the most precise choice.
