This study analyzed the actual vegetation and vegetation structure around the trails with the aim of restoring vegetation and continuous monitoring of the section between the National Astronomy Observatory and Birobong in Sobaeksan National Park. The actual vegetation was classified into 18 types, of which the largest were Quercus mongolica communities occupying the dimension of $225,337m^2$, Rhododendron schlippcubachii communities distributed around the trails on the ridge were covering 14.59%, and deciduous broadleaf forests were covering 11.06%. of the surveyed areas, respectively. In consideration of the actual vegetation, a total of 23 belt-transects were set up; 9 in Quercus mongolica communities, 3 in broadleaf deciduous forests, 2 in Taxus cuspidata communities, and 9 in damage restoration areas to take a closer look at the species diversity, species number, and individual number by community. The survey results are as follows: 9 belt-transects in Quercus mongolica communities showed their species diversity was $0.4290{sim}1.0496$ with $7{sim}22$ species and $115{sim}481$ individuals. 3 belt-transects in broadleaf deciduous communities showed that species diversity was $0.6712{sim}1.0096$ with $14{sim}17$ species and $158{sim}453$ individuals. 2 belt-transects in Taxus cuspidata communities showed that species diversity was $0.5413{sim}0.9923$ with $14{sim}15$ species and $223{sim}406$ individuals. 8 belt-transects showed that species diversity was $0.1899{sim}0.9217$ with $3{sim}23$ species and $105{sim}485$ individuals.
