Abstract:
Site A tree census for mortality in 2010.
Design:
Selected rows (every second or third) of each plot in Site A were controlled for tree seedling survival.

Name:
PTAG
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.

Name:
TAG
Definition:
The tree position tag is given to a tree individual growing at a specified position in the main experiment. In most cases, this is one tree individual, which is planted there. In case of replanting, more than one individual can be assigned this tree position tag. We still have to discuss how to deal with this situation. They begin with "t" for "tag" and then follow 12 digits...; Datagroup description: Tree or shrub position tag main experiment

plot
Definition:
plot number according to design spreadsheet. Plots are named according to their location on the original spreadsheet used for treatment design. This has letters from West to East and numbers from North to south. Some plots were moved half a gridcell (1 mu) so be suitable for planting (grid cell loctype); Datagroup description: Counting the individuals of a given taxon, also called abundance.
