Tree census and diameter increment in fertilised plots in the Central Amazon, 2017–2020

The dataset contains the Diameter at Breast Height (DBH) of trees > 10 cm along with botanical identification (family and species). Data were obtained via forest inventories, in annual campaigns (from 2017 to 2019) conducted in May, with exception of the first campaign, which was from June to November, due to the species identification activity. The research was conducted in a field site approximately 80 km north of Manaus, in the state of Amazonas, Brasil. The dendrometer dataset contains the distance in circumference (mm) from a window on the dendrometer band installed in the tree and measured with a digital caliper, where that distance changes when the trunk grows. Dendrometric bands data were collected from April 2018 to January 2020. Full details about this dataset can be found at https://doi.org/10.5285/c2587e20-ba4a-4444-8ce9-ccdec15b0aa3

本数据集收录了树木胸径（DBH）大于10厘米的树木样本，并附有植物学鉴定信息（科属和物种）。数据采集自森林资源清查，包括从2017年至2019年每年进行的年度调查（2017年首次调查时间为6月至11月，因物种鉴定活动而延长）。研究地点位于巴西亚马孙州马瑙斯市以北约80公里的野外场地。该树干径向距离数据集记录了从树干上安装的树干径向距离带窗口至测量点的周长距离（毫米），该距离随树干生长而变化。树干径向距离带数据收集时间跨度为2018年4月至2020年1月。关于本数据集的详细信息可查阅https://doi.org/10.5285/c2587e20-ba4a-4444-8ce9-ccdec15b0aa3。
