The purpose of this study was to analyze the deterioration of trail conditions and to obtain information for desirable maintenance and restoration of a trail in Deogyusan National Park. The physical characteristics of a trail were surveyed at a total of 412 sites over 79.8 km length. The average trail degree and width were found to be 14.31° and 1.60 m, respectively, while the average bare trail width was 1.40 m and the average maxim trail depth was 5.66 cm. Major deterioration types of trail were trail deepening (36.6%), rock exposure (33.9%), and root exposure (12.5%) in order of frequency. Deterioration classes of the trail were 0.626 km (0.8%), 3.110 km (3.9%) and 8.935 km (11.2%) for heavily, moderately, and lightly deteriorated, respectively, with a deterioration rate of 12.671 km (15.9%). Compared to other national parks, the ratio damaged trail to the total trail was 15.9%, which is slightly higher than other, including Jirisan National Park 9.6% (2019), Bukhansan National Park 13.6% (2019), Sokrisan National Park 11.7% (2019), Chiaksan National Park 12.3% (2015), and Woraksan National Park 10.5% (2015). The section of trail in Deokyusan National Park where the damage grade is analyzed as "Heavy" should therefore be restored in consideration of the field conditions. In particular, the damage status of the trail is expected to be greatly improved when the trail surface maintenance level is restored.

Six trails of Naesorak(west Sorak) district of Soraksan National Park were selected to investigate the use impacts on environmental edterioration of trail according to the different amount of use. The entire width, and slope of trail as the trail condition surveyed at the total of 132 points were significantly varied with the amount of use. Major deterioration types of trail were rock-exposure, root-exposure, deepening and divergence in order of frequency. Deteriorated points were significantly different in trail conditions from non-deteriorated points, and these latter generally appeared at the lowed altituede than the former on each trail. Naesorak district still seemed to have poorer use-impacts than Oesarak(east sorak) district. The dominant species in upper layer of trail edge vegetation differed from trail to trail, but in shrub layer Lespedeza maximowiczii, lindera obutsiloba for valley trail and Rhododendron schlipenbavhii for slope trail. The species diversity and coverage of shrub layer in trail edge were the highest on the Ose'am trail and each trail was dissimilar in species composition of shrub layer of edge vegetation.
