Abstract
This study was carried out to evaluate degradation status of forest trails by analysis of soil physical and chemical properties in Mt. Jiri area of Gyeongnam province. Soil texture was loam in the forest area and sandy loam in the forest trails. Soil bulk density was significantly higher (P<0.05) in the forest trails (1.15 g/$cm^3$) than in the forest area (1.00 g/$cm^3$). The rates of pore space were lower in the forest trails (56.6%) than in the forest area (62.4%). Soil moisture content was significantly different (P>0.05) between the forest trails (13.3%) and the forest area (11.3%) Soil strength was higher at 5 cm of soil depth than at 10 cm of soil depth. It indicates that soil compaction by visitors could be affected at 5 cm of soil depth. Soil strength over 30 cm of soil depth was not significantly different between the forest trails and the forest areas. The content of organic matter, total nitrogen, available phosphorus, and exchangeable cations were lower in the forest trails compared with the optimum content of forest soils because of soil erosion with increasing visitors. These results indicate that it needs a counterplan to protect forest trails from overcrowded visitors.
