Abstract

Larsen et al. (2019) found stubble heights measured at a systematic interval resulted in higher variability and lower stubble heights than samples collected at random. As the authors do not suggest an environmental mechanism for these outcomes, their conclusions likely reflect differences in the number of plants evaluated at each plot and the low number of independent observers rather than the sample design.
