In the early stages of soil formation, this process is easily disrupted. Any disturbance can dislodge the particles and cause them to sift deeper into the cinders, where they may be out of reach for use by plants; plants already established may also be dislodged. For this reason, it is important for visitors to stay on designated trails.
