In the forest, shrubs and trees with trunk diameter > 2.5 cm at breast height (DBH
) were tallied, as well as all plantation trees.
DBHs were measured in two directions perpendicular to each other.
(1999) found in a spacing study on Norway spruce only a slight but still significant effect of stand density on KD in addition to the effect of DBH. For this study, site index and stand density significantly reduced the residual variance when modeling KD and SKL.
Woody individuals with trunk diameter >1cm at breast height (DBH, at ~1.3m above soil) were tallied and DBH was converted to basal area (BA).
Most coffee shrubs were slender, ~1m tall and ~1cm DBH. They appeared to be saplings of the few remaining reproductive individuals and represented between 8.9 and 35.6% of the total stem density in BN1 in BN4, respectively.
We recorded the species of tree and the diameter at breast height (dbh
) of each stem used for foraging.
The first group consisted of larger woody species--one stem at least five centimeters diameter at 1.4 meters height (dbh
Diameter at breast height (DBH
) was determined from field measurements of tree circumference (diameter = circumference/[pi]).
Two stands each provided trees with DBHs
of 6, 7, 8, and 9 inches, respectively.

In the summer of 2005, seven trees [greater than or equal to] 8 inches in diameter at 4.5 feet aboveground (DBH
) were selected in proportion to the diameter distribution of the trees in each plot, were felled and destructively sampled for wood properties.
