Growth, mortality, wood density, biomass data from BIONTE inventories in Manaus, Brazil

BIONTE (BIOmass and NuTrient Experiment) is a selective logging experiment established at the Experimental Station of Tropical Forestry (EEST, aka “ZF2”) field research station in the mid 1980s in the central Amazon (Higuchi et al. 1997, Amaral et al. 2019). Led by the National Institute for Amazon Research (INPA) in Brazil, the project aimed at assessing the effects of logging intensity on forest dynamics and enabling the creation of a model of forest management for the Central Amazon. The experiment included three levels of increasing selective logging intensity and controls, with 1 hectare sample plots (12 total) located at the center of 4 hectare treatment plots. The site’s Köppen classification is tropical rainforest (Af), characterized by high temperatures and humidity, with mean annual temperatures around 27 ℃ and mean annual precipitation around 2200 mm of rain. The vegetation has a high floristic diversity, the soils of the region are poor in nutrients, and the topography is characterized by plateaus (where BIONTE is located), and also valley bottoms and slopes. The inventory (growth and mortality) and biomass data included here covers the 1990 to 2019 period, with wood density being averaged from existing datasets. This dataset includes a data file in .csv file format and a .txt file, BIONTE_mortality-rates_headers.txt, that provides descriptions for the data file headers. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archivalBIONTE（生物量与养分实验，BIOmass and NuTrient Experiment）是一项择伐实验，于20世纪80年代中期在亚马逊中部的热带林业实验站（Experimental Station of Tropical Forestry，简称EEST，又称“ZF2”）野外研究站设立（Higuchi等，1997；Amaral等，2019）。本项目由巴西国家亚马逊研究所（National Institute for Amazon Research，简称INPA）主导，旨在评估伐木强度对森林动态的影响，并为亚马逊中部地区构建森林管理模型。实验设置了三个梯度递增的择伐强度组别与对照组，共包含12个1公顷样地，所有样地均设于4公顷处理样地的中心区域。该站点的柯本气候分类法（Köppen classification）分类为热带雨林气候（Af），具有高温高湿的气候特征，年平均气温约27℃，年平均降水量约2200毫米。区域内植被物种多样性丰富，土壤养分贫瘠，地形以高原（BIONTE实验所在地）、谷底与坡地为主。本次收录的森林清查（生长与死亡动态）及生物量数据覆盖1990年至2019年时段，木材密度数据由现有数据集整合平均得到。本数据集包含.csv格式数据文件与一份名为BIONTE_mortality-rates_headers.txt的文本文件，该文件对数据文件的表头信息进行详细说明。本数据集最初发布于NGEE热带档案馆（NGEE Tropics Archive），现由ESS-DIVE镜像存储以实现长期归档。
