This file contains the following fields:A) P: Plot identifier number. B) PlotBasalArea: Tree basal area of the plot (m^2/ha). C) MinTemp: Predicted minimum air temperature on the coldest night at height of 1 m (C). D) Phys: Physiognomy of the plot 0 = shrub savanna, 1 = tree savanna, 2 = forest. E) TagNumber: Identifier number for trees that were permanently tagged. F) Species: Binomial latin name. G) Species.Code: Four-letter abbreviation of species. H) Type: S = savanna specialist, F = forest specialist or generalist. I) InitialHeight: Height prior to frost (cm) J) FinalHeight: Height one year after frost (cm) K) LeafDamage: Fraction of leaf area damaged, as visually estimated several days after the coldest frost event (cm). L) DiebackHeight: The height from which the stem resprouted, as determined one year after the severe frost (cm). M) Dieback.length: The loss amount of stem height lost due to dieback (cm). N) CrownExposure: A unitless index of canopy exposure: 1 = receiving no direct light; 2 = receiving some direct lateral light; 3 = receiving some direct overhead light, but with <90% of the crown exposed to overhead light; 4 = receiving direct overhead light on >90% of the vertical projection of the crown; 5 = receiving direct light on all sides (an emergent tree or open-grown savanna tree). O) dieback.binary: A binary indicator of damage. 0 = no damage; 1 = damaged. A plant was considered damaged if it exhibited at least 50% leaf damage. For individuals without leaf damage data, an individual was considered damaged if it exhibited any amount of stem dieback. P) RegrowthLength: The recovery of height, from the point of dieback, for plants experiencing any amount of stem dieback (cm) Q) NetChange: The net increase or decrease in height as determined one year after the severe frost (cm). This net change is equal to InitialHeight-FinalHeight and is also equal to RegrowthLength-Dieback.length.
