Erosion caused by climbing mountain practice on the trail to Camapuã and Tucum peaks – Campina Grande do Sul (PR).

Abstract

The objective of this work was to evaluate the erosion caused by climbing mountain practice on the trail to Camapuã and Tucum peaks – Campina Grande do Sul (PR). The use intensity was obtained through interviews. The trail, divided in four sections, was delimited using a GPS. In each section it was evaluated the slope, depth, width, and extension of the trail as well as the type of soil covering, the formation of steps and rill erosion and the exposition of the soil, root, and rock. The erosion intensity in the trail was calculated considering the depth of the trial and the formation of steps or rill erosion. The trail presents different use intensity, it was estimated the walked by number was 1023, 868, 711 and 141 in section 01, 02, 03 and 04, respectively. The erosion intensity was modified with the use intensity, slope, vegetal covering and soil class. It was classified of very low to very high, according with the increase of the use intensity and slope. The vegetation decreases the erosion intensity. However this effect decreases with the increase of the use intensity and slope.
