ATTRIBUTES

Field	Name	Definition	Unit	Code
1	Block	block one is to the east in a smaller enclosure and block two is to the west in a larger enclosure, loser to FAB.
2	Plot	These numbers are duplicated across blocks, so each block has plot 1-18.
3	Row	Numbered across the block so that plots 1-6 have rows 1-11, plots 7-12 have rows 12-22, and plots 13-18 have rows 23-33.
4	Column	Lettered across the block so that aa comes after z. Plots 1, 7, and 12 have columns a-e, etc.
5	Species	Species identifier		s=SANI, p=POTR, a=POAL
6	Genotype	An arbitrary number designating which genotype within a species the tree corresponds to.
7	SR	The species richness of the plot.	Count
8	GR	The genotypic richness of the plot.	Count
9	Treatment	A code indicating the set of factor-levels for the plot. 1S3G = 1 species, 3 genotypes
10	Composition	A code indicating the particular composition of the plot. 3.3_A6_S3_T2 means a 3-species, 3-genotype plot with genotypes A6, S3, and T2.
11	D_15 (mm)	Basal diameter of the leading (tallest) stem in September 2015 in mm.	millimeter
12	H_15 (cm)	Height to tallest leader of the leading (tallest) stem in September 2015 in cm.	centimeter
13	D_16 (mm)	Basal diameter of the leading (tallest) stem in September 2016 in mm.	milliliter
14	H_16 (cm)	Height to tallest leader of the leading (tallest) stem in September 2016 in cm.	centimeter
15	dead_15	0 indicates alive and 1 indicates dead in September 2015. Dead trees in 2015 died after replanting in June 2015.
16	dead_16	indicates alive and 1 indicates dead in September 2016.
17	leaf_Rem	categorical measure of leaf damage		1=up to 0.5 cm2 removed, 2=up to 25 percent of leaf area removed, 3= more than 25 percent removed
18	galls	Number of stem and leaf galls recorded on entire plant. 10 indicates 10 or more and is used only when there were too many to count.	Count
19	leaf_miner	Number of leaf miner tracks recorded on all leaves. 10 indicates 10 or more and is used only when there were too many to count.	Count
20	leaf_gall	Leaf gall presence		0=not present, 1=present
21	stem_gall	Stem gall presence		0=not present, 1=present
22	scale	Scale presence		0=not present, 1=present
23	ants_aphids	Ants ad aphid farming present		0=not present, 1=present
