Dataset size: 23,084 x 23
Indicates 23,084 individual dynamics data points with 23 columns of information per data point.
Data is similar to Fixer_Nonfixer_Dynamics_SP.csv but the dynamics are not partitioned by N-fixer and non-fixer.



Column Name:			Description:				Range: 			Units:			Notes:
Year				Year					1983-2013					
PSP				Plot number				1-93 						Arbitrary plot identity index (each 1 hectare)
SP				Subplot number				1-25 						Arbitrary subplot identity index (each 400m2)
bin				Categorical diameter bin class		1-3 						1 for stems with diameter at breast height < 30cm, 2 if >30cm but <60cm, 3 if >60cm
Harvest				Binary harvest variable			0-1						1 if potentially subjected to harvest, else 0
N.sp				Stem density				1-28						Number of stems in the subplot, regardless of bin
N.bin				DBH bin specific stem density		0-23						Number of stems in the DBH bin category in the subplot
Nf.sp				Total N-fixers in subplot		0-15						Total number of N-fixers in the subplot, regardless of bin
pf.sp				Proportion of N-fixers in subplot	0-1						Total proportion of N-fixers in the subplot, regardless of bin
pf.BA.sp			Proportion of N-fixer BA in subplot	0-1						Total proportion of N-fixer basal area in the subplot, regardless of bin
SR.sp				DBH bin specific species richness	1-14						Species in the subplot, regardless of bin
rgr				Relative growth rate			0.2-12			%/year			Average relative growth rate across subplot
AGB				Aboveground Biomass			0-51942			kg			Total AGB across subplot
BA				Basal Area				0-11			sq. meters		Total BA across subplot
AGB.delta			Change in AGB				0-8131			kg/year			Change in total AGB between the previous census to the indicated year
R				Recruitment biomass			0-10431			kg			AGB of recruits across subplot
M				Mortality biomass			-12974-0		kg			AGB mortality across subplot (all negative indicating lost biomass)
R.r				Recruitment rate			0-0.67			fraction/year		Average recruitment rate between the previous census to the indicated year (multiply by 100 for %/year)
born				Number of new stems between census	0-6.5						Number of stems that are assumed recruits as they were not previously censused
M.r				Mortality rate				0-1.75			fraction/year		Average mortality rate between the previous census to the indicated year (multiply by 100 for %/year)
dead				Number of missing stems between census	0-4						Number of stems that are assumed dead as they were not re-censused across the time interval
alive				Number of remaining stems between census0-20						Number of stems that are assumed to have persisted across the time interval
T.r				Turnover rate				0-1			fraction/year		Average turnover rate between interval
