Estimates of treatment effects on plant sizes of all species throughout the growing season.

Effect values other than the intercept (here: Normal treatment) are deviations from the latter. Species-specific size measurements were scaled to a common range between 0 and 1. Given are standard deviation (sd), t- and p-value and degrees of freedom (df) of the model. Normal = unmanipulated snow cover; Removed = snow removal on 1. May; Shallow = naturally early snowmelt; Medium = intermediately increased snow; Deep = maximally increased snow.
