 note = {application/pdf, We identified a site on the Toyohira River in Sapporo, Hokkaido, where the area of mid-channel trees is expanding. This identification was done based on aerial-photograph-based drawings indicating changes in tree height and area of mid-channel trees between 1972 (the year before improvement work, when channel trees were few ) and 1995 and 2003 (years after the work was complete). Based on a cross-sectional plan of the side, we examined changes in the riverbed topography and height difference between 185-day water level and maximum riverbed height in the low-water channel for each year. Furthermore, in the present topography, we estimated the age of seedlings along a measurement line on the bare part of sandbars distributed with seedlings, and determined inundation frequency during the period of seed dispersal, inundation frequency during the period of tree growth, maximum annual non-dimensional tractive force, and change in tree height between 2002 and 2004 when seedlings began to establish themselves. Then we conducted factor analysis on seedling habitats and environment. We found that inundation frequency during the period of seed dispersal affects the establishment of the seedlings. This suggests that adjustment of the flow volume in the period may control the establishment of seedlings.},
