Table 7 Means of DBH, HT, and AGB of trees from the 1987 German National Inventory used in this study

From: Model errors in tree biomass estimates computed with an approximation to a missing covariance matrix

  Trees DBH (cm) HT (m) AGB (kg/tree)
BEECH 1,595 35 (15) 25 (7) 1,111 (1,110)
SPRUCE 2,221 30 (12) 24 (7) 492 (460)
PINE 1,221 33 (12) 23 (6) 1,100 (410)
  1. Standard deviations are in parentheses. Note, the mean applies to the population from which 50 trees were selected at random for model-fitting and B = 800 sets of 50 trees were selected for the recovery process (a tree used for model fitting was disallowed in the recovery process). See Table 1 for details on sample tree selection.
