Tables: Sampling prefectures of data and statistics of nutrient storage and stoichiometry of the forest floor in Japanese forests.

Dry weight and nutrient (N, P, K, Ca, and Mg) storages of the forest floor organic layers in Japanese predominant forest types were meta-analyzed. Stoichiometric ratios (C:N, C:P, N:P) were also analyzed. Number of data in the prefectures of Japan were shown in the table (Table S1). The statistics of the data are summarized in the table (Table S2 -S13).
