The q90spp zipped files contain compressed text files of the 1982-1990 census data for all stems in the BCI 50 ha plot, separated into individual files for each species. The other zipped files contain the files generated from the 1990 census, with measurements of: old trees, new recruits, multiple stems, and buttressed trees. All trees >=10 mm dbh were tagged, measured, mapped and identified to species.q90spp压缩包文件包含1982-1990年BCI 50公顷样地内所有植株的普查数据压缩文本文件，且按物种拆分为独立文件。其余压缩包文件内含1990年普查生成的数据集，涵盖老树、新补充个体、多茎植株以及具板状根的树木的测量信息。所有胸径（DBH，diameter at breast height）≥10毫米的树木均被标记、测量、绘图并鉴定至物种水平。
