Sampling comments: "This study was done from June - August, 2004"
four 4 x 10 m quadrats were centered on each of 15 "remnant trees" that had existed in the pastures at abandonment; they "were established in the each of the cardinal directions extending outward from the bole of the tree" starting at the edge of the tree itself
table giving basal area is misformatted, with "Basal area" heading the column to the left of the actual basal areas
