Soil erosion is a natural process in which topsoil displaces by dynamic activities of wind and water, leading to possible soil degradation. However, the usage of trails increases with the frequency and intensity of tourists and trail events these years, which accelerates the degradation of popular trails. Different types of erosion therefore occur, such as the formation of gullies.
The gullies through which runoff water and abrasive particles flow will be deepened and widened if no mitigation measure is taken.
Erosion reduces soil support to trees which then may easily fall.
A path was divided into two.
Plants situated in between are isolated and will receive less water and nutrients.
Potholes form when rainwater with stones erodes soils and spins in the concave.
Stairsteps could not sustain if we do not make waterflow gentle.
Visitors sometimes do not want to climb staircases or step in puddles so they may walk off-trail. Stepping on vegetation aside the paths would however halt the growth of plants. Those paths will be widened with no more greenery.
Shortcuts are often found at S-shaped trails. Quick-tempered hikers tend to open up a more direct path through steping on vegetation and adversely affect growth of plants.
Trails paved with cements do not integrate with the natural environment.
