Abstract:
This data documents the tree growth parameters for seven years from 2011 to 2016 for site B of the main experiment. Measurements for this data took place at the end of the growing season of deciduous trees, mainly in September and October of each year. Measurements were conducted in the central part (extended core area) of all 1mu-plots in site A. Extended core area is the central 6 * 6 trees in the monoculture and 2-species mixtures (total 36 tree positions per 1mu-plot), the central 12 * 12 trees in the 4-,8-,16-,24-species mixtures (total 144 tree positions per 1 mu-plot). By applying the conventional measuring methods direct in the field, tree position, tree species, total height, stem diameter 5 cm above ground height (gd), the diameter at breast height (dbh), the crown diameters (N-S and E-W) were measured in all years. For the years 2010 to 2013, the distance up to the first branch, the distance up to the longest branch, the diameter, the length, the azimuth and the angle of the longest branch were measured additionally and the number of branches were counted.
Design:
All tree positions in the so called extended core area for each 1mu-plot were surveyed. The extended core area is the central 6 * 6 tree positions in the monocultres and 2-species mixtures (36 tree positions per 1mu-plot) and the central 12 * 12 tree positions in the 4-, 8-, 16- or 24- species mixtures (144 tree positions per 1mu-plot). Note: In 2016 a reduced sample, except for VIP and VIPrep plots, of only the central 6 * 6 tree positions in each plot was measured.
Spatial extent:
This data was collected from site B within the BEF-China experiment, which is located in a hilly subtropical region near Xingangshan Township, Jiangxi Province (29.08-29.11 N, 117.90- 117.93 E), China.
Temporal extent:
During the end of growing season of deciduous tree species. Mainly September and October of each year (2011 to 2016).
Taxonomic extent:

Definition:
plot code, BEF research plot name, 6 digits with "p" in front; Datagroup description: Research plots of the Biodiversity - Ecosystem functioning experiment (BEF-China). Main Experiment plots have a size of 1 mu, which is about 25x25m^2 in horizontal projection. Pilot Study Plots have a size of 1x1 m^2. Research plots on the main experiment have a "p" in front of their IDs and then a 6 digit code: Plots in the main sites A and B are named according to their position in the original spreadsheet, in which they were designed. They consist of 6 digits: _1st digit_: Site (1:A, 2:B), _digit 2and3_: southwards row: as in spreadsheets the rows are named from the top to the bottom; _digit 4 and 5_: westward column: as in the original spreadsheet, but the letters are converted to numbers (A=01, B=02); _6th digit_: indicator, if the plot has been shifted a quarter mu. Example: "p205260": "p" means that this is a plot that is specified. "2" means, that we are at site B. Now the coordinates of the south - west corner: "0526". Since "e" is the fifth letter of the alphabet, this is Plot E26. The last digit "0" means that this plot was not moved by a quarter of a Mu, as some sites in Site B. The 6th digit can also indicate the subplot within the plot. "5", "6", "7", "8" indicate the northwest, northeast, southeast, and southwest quarter plot respectively.
