The AT is an established foot path constantly being maintained and even relocated to keep its travel surface durable and reduce erosion. This is why it is important to stay on designated trails. The trampling of vegetation is a leading cause of impact in the backcountry. As vegetation gets trampled, signs of wear invite more use, which causes more trampling, resulting in side trails, expansion of campsites and enlargement of rest areas, summits and trails.
Compaction goes along with trampling vegetation.
As our body and pack weight compress the soil, we remove oxygen and water, necessary elements for root systems. The Trail in Maine passes through Sub-Alpine and Alpine zones. Soil is thin and vegetation works hard to survive. Trampling here is devastating to plants. Trail builders take into account erosion control, ease of travel and picturesque scenery.
