This paper reports the data collected in censuses of trees, litter fall and vegetation in a mountain riparian forest, upstream of the Watarase river, Gunma Prefecture in central Japan. A 1‐ha permanent plot (100 m × 100 m) subdivided into horizontal 10 m × 10 m grid cells was established in the forest in 2005. Tree census with woody species ≥15 cm girth at breast height was conducted every year from 2005. Twenty‐five litter traps were set in the permanent plot. The samples of litter fall were collected monthly, except in winter, between 2005 and 2008. And we sorted into leaves, branches, reproductive organs and other plant material, at species level as much as possible. The percentage cover of vascular plants was recorded at each vertical stratification (tree layer, subtree layer, shrub layer and herb layer) in 2008 and 2014 at the plot. These data are valuable for elucidating long‐term forest dynamics at mountain upstream areas experiencing frequent ground disturbances.

日本中部上游山谷的河岸森林结构与动力学

本文报道了日本中部群马县渡濑濑川上游的河岸森林树木，凋落物和植被的普查数据。2005年在森林中建立了一个1公顷的永久性地块（100 m×100 m），细分为水平的10 m×10 m网格单元。从2005年起，每年进行一次木种调查，其中木本植物的胸围长≥15 cm。永久性小区内设置了25个垃圾收集器。2005年至2008年之间，除冬季外，每月收集凋落物的秋天样本。我们尽可能按物种级别将其分类为叶子，树枝，生殖器官和其他植物材料。在该地块，分别于2008年和2014年记录了每个垂直分层（乔木层，次乔木层，灌木层和草本层）维管植物的覆盖率。
