    Variance estimates are rarely reported or rigorously determined for net primary production by higher aquatic plants, yet the variance must be known before production estimates can be compared conclusively. First-order error analysis is used here to derive formulae for estimating the variance of annual net production determined by demographic methods. Demographic methods determine net production of even-aged cohorts by analyzing curves of survivorship versus plant mass (Allen curves). Allen curves may be interpolated linearly or logarithmically. Calculation formulae for both alternatives are derived and compared in a common framework. Logarithmic interpolation is more consistent with observed thinning dynamics of even-aged plant stands.
