Dataset Abstract
Data on basal are increment of five year periods as counted from the rings of basal discs, of harvested trees by Martin Baruffol and Matteo Brezzi in autumn 2010. A total of 160 individuals were harvested and measured belonging to eight species. For some individuals it was not possible to see the rings, these individuals were left out and are thus not included in this table.
Dataset Design
Trees were cut and the volume of their woody parts measured up to 3 cm diameter, rest of it was fresh weightes. Samples of wood, branches and leaves were taken to calculate dry weight and estimate tree biomass. In this dataset, we focus on the tree growth out of tree ring analysis. We measured the area of growth during periods of five years for each individual when possible and counting backwards since 2010.
Spatial Extent
In a forest nearby to Xingangshan we harvested 160 trees out of eight species.
Published
The data has not yet been published
Temporal Extent
Trees were harvested in autumn 2010 and ring analysis was done autumn 2012
Taxonomic Extent
Eigth common species of the forest (coniferous: Cunninghamia lanceolata, Pinus massoniana. Evergreen: Castanopsis fargessi, C.sclerophylla, Schima superba. Deciduos Alniphylum fortunei, Liquidambar formosana, Sassafras tzumu)
Data Analysis
Basal area increment of series of five years is analyzed as a function of initial size, species identity, neighborhood competition and diversity, and geoform.
