Abstract
<p>UAV photogrammetry was used to obtain the spatial distributions of ground height and vegetation height in a sandy, oligotrophic wetland in Naruto-Togane, where carnivorous plants grow. The correspondences between these ground and vegetation height distributions, groundwater quality, and vegetation distributions of Iris ensata, Patrinia scabiosifolia, and Phragmites australis were analyzed. The entire wetland is burned totally at the end of January every year and irrigated after the burning in order to preserve the carnivorous plant community in this wetland. Immediately after the burning, the 3D ground surface was measured using stereo photographs from a UAV. The 3D plant canopy surfaces of the entire wetland were also measured in June and September, when Iris ensata and Patrinia scabiosifolia were in bloom, respectively. The ground resolution was 15 mm. As a result, the ground surface elevation values were obtained with the average error of 33 mm. The spatial distribution of vegetation height was obtained from the ground and vegetation surface measurements. The wetland characteristics shown in this study provide the basis for the conservation of Naruto-Togane wetland.</p>
