Dataset Abstract

Data on the individual total dry biomass of the individuals in the center of each plot in the pilot experiment harvested in autumn 2010

Dataset Design

The aboveground section of the four central individuals of each plot (corresponding to subproject SP01) was harvested and dry weighed

Spatial Extent

The experiment was located within N29 06.325 / E117 55.244, in the south-west N29 06.293 / E117 55.235, in the north-east N29 06.295 / E117 55.326 and in the southeast N29 06.266 / E117 55.329 in the lower valley of Tiquanshui river (体泉水),Xinjianxiang, Jiangxi Province

Temporal Extent

Last measurement of the data was done the first week of september 2010. Since then the individuals were harvested. Last weighing were done up to mid october 2010

Taxonomic Extent

Four central individuals of each plot in the pilot experiment, from the plots measured by SP01. It includes data on saplings of twelve species (Castanea henryi, Elaeocarpus decipiens, Quercus serrata, Schima superba, Cunninghamia lanceolata, Cyclobalanopsis glauca, Dalbergia hupeana, Pinus massoniana, Castanopsis sclerophylla, Cyclobalanopsis myrsinaefolia, Sapindus mukorossi, Lithocarpus glaber)

Measurement Circumstances

No particular additional comments

Data Analysis

Plot and individual biomass is analyzed as a function of the richness, treatment and other covariates
