This experiment was done within the macroplots in field D (see E004 for plot layout and treatments). In 1990, a biomass strip was taken from each of the nine replicates. The 3m x 10cm strip was taken from the center of the 10m x 10m section in the most southeast corner of the first eight replicates (D1-D8), and from the most southwest section of D9. In June of 1991, all trees and saplings were spatially mapped within the 50m x 20m plots, their dbh measured and heights and vigor estimated. In June of 1991, growth response of the trees was measured. In August of 1991, herbaceous cover was recorded and canopy cover directly overhead was estimated.
