Abstract Camping is one of the popular recreational activities in mountain national parks. However, human activities inevitably cause impacts on natural resources, which includes vegetation loss, soil compaction and soil erosion (Hammitt and Cole 1998). The degraded environment also does harm to users experiences in return (Daniels and Marion 2006). In order to provide users with high quality camping experiences meanwhile avoid unacceptable impacts on the natural environment, monitoring and maintenance of campsites are necessary. Researchers in the field of recreation ecology have provided a sort of methods to monitor short-term and long-term changes in the condition of campsites. Methods to detect areal changes in bare ground and vegetation loss on campsites have been widely practiced in previous studies (Marion 1991, Wang and Watanabe 2019). Eagleston and Marion (2017) examined soil loss on campsites by comparing the current soil level around embedded rocks on site with the one recorded in past photographs through visual observation. Wang and Watanabe (2019) adopted Structure-from-Motion (SfM) photogrammetry mapping to obtain detailed profiles of the ground surface on the campsite where gully erosion was observed. However, no studies have been conducted to monitor the volumetric changes in ground surface on campsites that are suffering from soil erosion.This study aims to detect topographic changes of the ground surface and to quantify the volume of soil erosion on the current and former Kuro-dake campsites in the Daisetsuzan National Park (DNP) by SfM photogrammetry surveys.
