ATTRIBUTES

Field	Name	Definition	Unit	Code
1	Year	Year of burn
2	Plot	Plot number in E120
3	SpNum	Number of species planted in plot including seed contaminent and replacement for species belived to have bad seed (for core E120 diversity experiment plots; blank for other plots in the same field)	dimensionless
4	NumSp	Number of species planted in plot as specified by treatment (for core E120 diversity experiment plots; blank for other plots in the same field)	dimensionless
5	percentBurnFirstIgnition	percent of plot area that carried fire following just one ignition	dimensionless
6	percentBurn	percent of plot area that carried fire, including any areas burned in additional ignitions if the first ignition did not carry through the whole plot	dimensionless
7	biomassHerbaceousPrev	dry mass of herbaceous biomass measured in the plot late the previous summer	gramsPerMetersSquared
8	biomassGrassProportionPrev	proportion of the dry biomass in the plot that was grass, late the previous summer	dimensionless
9	biomassLitterPrev	dry mass of litter measured in the plot late the previous summer (litter being from an earlier season than the season it was measured)	gramsPerMetersSquared
10	biomassHerbaceousPlusLitterPrev	combined dry mass of herbaceous biomass and litter, measured in the plot late the previous summer	gramsPerMetersSquared
11	herbaceousCoverAbsPrev	Proportion of plot area covered by herbaceous plants late the previous summer (as a proportion ranging from zero to one).		0=bare ground (or woody plants but those were rare) with no herbaceous plants, 1=complete cover of herbaceous plants
12	grassCoverProportionOfHerbaceousPrev	Proportion of the herbaceous cover in the plot that was grass, late the previous summer	dimensionless
13	FlameFront	Width of flame front on which following fire behavior measurements performed	meter
14	FlameHeight	Flame Height	meter
15	rateOfSpread	rate of forward spread of flame front	metersPerSecond
16	flameDepth	depth of flame front	meter
17	BurnType	head or back fire		head=head fire, back=back fire
18	FlameAngle	flame angle 0=flat through 90=upright	degree
19	flameLength	Flame length	meter
20	PercolatedInferred	Whether fire carried at least 7 m, scored from post-burn photo		1=spread from one side of plot to other (7 m from ignition to within 2 m of far edge), 2=failed to spread from one side of plot to other
21	Percolated	Whether fire carried at least 7 m, scored from video of burn		1=spread from one side of plot to other (7 m from ignition to within 2 m of far edge), 2=failed to spread from one side of plot to other
